In this post we learn how to make a simple 3 phase brushless DC motor driver circuit. The circuit employs the popular IRS2330 3-phase driver IC
The presented idea looks simple since most of the technicalities is taken care of efficiently by the IC itself, it's all about connecting the relevant pinouts with the few external supplementary components for the required implementations.
How BLDC with Hall Sensors Work
We know that all BLDC motors fundamentally incorporateHall sensors附着于它们的定子组件，其中这些装置在检测和提供控制电路方面发挥关键规则，其中具有关于转子磁铁瞬时位置的必要数据定子线圈激活.
该信息有助于控制电路随后顺序地转换定子电磁铁激活，使得转子恒定地体验旋转扭矩并产生预期的旋转运动。
Therefore it seems that the hall effect sensors are the ones that become solely responsible for detecting and inducing the intendedrotational motion in BLDC motors.
与霍尔传感器连接的控制电路实际上是“盲目的”，并完全响应霍尔传感器信号，以便将所需的进料产生回电磁铁线圈。
上述事实实际上使得设计了3相BLDC电机控制器的设计非常简单，简单地还进一步辅助通用3相的可用性H bridge driver ICsuch as the IRS2330.
Studying the IC IRS2330 Specifications
The following discussion provides a comprehensive view on the designing of a 3 phase brushless BLDC motor driver circuit:
引脚的IC详细信息
The above shows the pinout diagram of theIC IRS2330which simply needs to be connected to a set of a few external components for implementing the proposed BLDC controller circuit.
How to Configure the Full Bridge IC
在上图中，我们目睹了用一些外部部件连接IC引脚的方法，其中右手侧IGBT阶段使用6表示标准的H桥接配置IGBTs与IC的适当引脚集成。
The above integration concludes the output power stage for the BLDC controller circuit, the "load" indicates the BLDC 3 phase electromagnet coils, now its all about configuring the inputs HIN1/2/3 and LIN1/2/3 of the IC with the relevant hall sensor outputs.
NOT gates for Sequencing the HIN, LIN Inputs
Before applying the hall sensor triggers to the driver IC inputs, it's required to be buffered through a couple of NOT gates as given in the diagram above.
Finally, the outputs of theNOT gatesis integrated appropriately with the inputs of the IC IRS2330.
The negatives of all the hall sensors may be assumed to be grounded.
The second circuit which forms the main driver configuration for the proposed3相无刷BLDC电机驱动器circuit, could be also seen having a current sensing stage across its lower left section. The resistive divider may be appropriately dimensioned for enabling an over current protection and control over the connected BLDC motor.
For getting comprehensive details regarding the current sensing configuration and other intricacies of the whole design, one may refer to the following datasheet of the IC:

Sir, how can we use your simple inverter circuit to use for charging purpose too with simple modification like using relay only. So it charge the battery and provide some backup on power cut. We can make it manual to backup process on when power cut (to avoid some complex modification in circuit) I got mosfet invertor circuit (it using hcf4047be ic) of 100 w from junk and want to use same transformer to charge the battery and for convertor purpose. Using 9-0-9 transformer we can get 18v to charge the battery as well with using of some diode to step down the current to 14v
For eg can you provide that modification on this

Looking forward to hearing from you.
亲切的问候
内存, you can take the help of the following example circuit for your application, just observe how the relay contacts are wired up with the trafo and the battery for the required changeovers, you may replicate the connections for the same:

sorry I am not so well versed with BLDC motors, the three wires probably would need to be connected across the three outputs from the bridge as shown in the above diagram
ANY MOD REGARDING 'REWIRING PS2 MOUSE TO USB '???
这是否消除了Esc的要求是无刷DC
motors?
it's only a BLDC driver, it does not include a speed control feature….the speed control can be achieved by adding a PWM to the low side mosfet gates via a 555 PWM circuit.
Hey Mr. Majumdar,
Do you have any guides regarding a brushless sensorless motor control circuit? Am looking for any guides to help me out. Also I am willing to pay for some circuit designs if you are able and willing to help.
问候，
Amit

sir,how to connect hall sensor to irs233
If possible I'll update the info soon in the above article.
Hi Swagatham,
Liked the circuit, got the whole circuit set up.
But not sure what to give as input to Hall1, Hall2, Hall3.
Guess there should be a logic circuit, please help me with that.
谢谢
Uday
谢谢Uday, the hall sensors are supposed to be attached with the BLDC motor …however if you intended to create the signals artificially, you can do it by following the concept which is explained in the following article
https://www.homemade-circulay.com/2016/12/3-phase-solar-submersible-pump-inverter.html.
谢谢你。我正在努力使用1kW BLDC电机从头开始建立自己的电动机自行车。我正在寻找简单的速度控制器设计，你有什么建议让我开始吗？
Thank you
You can try the concept explained in the following article, it's probably the easiest one
https://www.homemade-circulay.com/2016/12/3-phase-solar-submersible-pump-inverter.html.
sorry I am not good at coding MCUs, so it can be difficult from my side.
你好。我可以使用另一个IC而不是IRS2330？
yes you can replace it with any other IC having identical features….
Irs 2330 packages not easy to connect to.
The hall sensors on my BLDC work like a switch. They furnish a common (closed) signal or an open. If I connect vdd (+12vdc) to 12v led then to sensor lead it lights up as motor turns
yes that's fine, you will need to configure them with the 4049 gates as suggetsed in the above article.
I'm waiting on 4049 in dip configuration. I should have been more careful to pick a config that meshes with my project boards .100 through board holes. Could use Arduino digital inputs but like your idea better. No programming!
thanks, by the way did you check the other BLDC drivers published in this blog? those surely seem to be more compact and advanced than the above concept
I bought some but didn't YET feel I could use them. I need dip chips and those are typically in other formats
you can use any type, as long as it is solderable
I'm using 2130 ic with same pinout as 2330. Finished testing and ready to hook up to motor. Not sure how to control forward and reverse. Any thoughts?
可以通过反转3相输入信号序列来实现FWD反向
谢谢。我会试试并报告
请告诉我一个控制电动车的交流电动机的电路电压电压为230V 400amps
you can try the following concept for it
https://www.homemade-circulay.com/2017/07/universal-esc-circuit-for-bldc-motors.html.
I bought a BLDC controller with forward reverse and speed control. Pot for speed control appears to be dual gang but only 3 terminals. 3K between red and black regardless of wiper position. Resistance between white and either red or black varies but is same. Gets up to 20K near midpoint then backs down. Seen this kind of pot before
不，我还没有看到具有这样的响应的盆，电阻应根据旋转方向比例增加或减小，直到终点到达，它不应该改变中途的过程。
yes, but this may happen, if the two end terminals of the pot are shorted, and the the response is measured across this common shorted terminal and the center terminal….
If the two pots are paralleled internally but wired opposite you would get Max at midpoint and less toward either end. But motor speed continues to increase as pot is rotated. Thanks
看起来很奇怪，你可以尝试从电路板拆下它，然后检查其电阻值
Hi, what mosfet or igbt would you recommend for a 1000w motor

sorry nobody’s within my range at the moment…..
Hi,
First, thank you for all that you’ve done so far. I’m trying to use a salvaged Segway motor from an i657 as as a servo motor for a CNC machine, and I’m curios to know if you have any idea how I would wire it to your circuit. I’m getting confused because this motor manufactured by Pacific Scientific has no available data sheets. It has a PCB lead attachment with 6 coil inputs in matching sets of three wires, and what appears to be 2 matching hall sensor outputs with 7 leads each. The PCB has two 53ND12-Y relays on it, and two diodes. I’m becoming slightly frustrated with the lack of information about this motor’s control needs. I’m sorely tempted to desolder the PCB, and just get an aftermarket encoder for positional feedback. Any suggestions? Once again, thank you so much for this resource!
Hi, I wouldn’t recommend going ahead with this project if you are not sure about the motor wiring specifications. Because the 3 phase driver explained above itself is a complex circuit which will need appropriate expertise in the filed to succeed, so you must take special care to ensure everything is perfectly known before implementing this project
I’ll get whatever expertise I need. I’ve built several stepper motor CNC machines before, as well as 3D printers, foundries, cars, airplanes, rockets, and have overseen national projects for several governments. I built an integrated vehicle computer system in my offroad vehicle in 2001 that had a tiltometers, was voice activated, and would talk to me for feedback. I think I got this. I was hoping to not have to build my own controller, but since there’s no specifications available for this motor, I’ll have to reverse engineer it. Thank you for the schematics you’ve made available, I’ll just have to pull out my old electrical engineering textbooks my father-in-law gave me. I was just being lazy. There is no intellectual pursuit I’m incapable of succeeding at. If anyone wants to give help, I’ll take it, but I’m not afraid of learning what I need to succeed.
OK fine, then you can give it a try.
谢谢for allowing me to proceed. I was concerned you might not give me permission. I’ll post back in a few months when my prototype testing is completed to see if my solution meets with your approval.
No problem! Wish you all the best!
你好Swagatam.
First of all congratulations for the great job done !
I have a new BOMA MOTOR Co bought in Chine that arrived with the controller completely damaged. I borrowed a controller from a friend and test the BLDC motor that works great.
Specifications are 48 VDC, 1000 Watt, 2800 RPM.
电动机具有用于磁场的三根厚的电线和霍尔效应传感器的5根细线。
I have followed and studied all the circuits you have published in the 11 pages of Motor Controller Section.
I see your have two approaches: one using IRS2332 plus IGBTs, the second using MC33035 plus IGBTs.
Which one you advice me for my case ?
May I get details for components whose characteristics are not listed ?
谢谢for your help, kind regards from Buenos Aires !
霍西奥
Hello Horacio, the hall effect sensor is supposed to work with 3 wires for the control circuit and 3 wires to the ground.
With 5 wires I have no idea which circuit would suit your motor.
MC33035使用传感器的3个电线配合使用，因此它可能与您的5个线电机不兼容。
艾尔ternatively if you want to ignore the hall effect feedback then the 3 thick wires could be directly used with any 3 phase controller like the IRS2332
你好Swagatam.
谢谢你的快速帮助！
I suppose that the Hall wires are perhaps connected in a Star, or grounded in a special manner.
So I wrote to the factory asking the internal wiring diagram for the motor. Perhaps tomorrow morning I get it.
Independently of that, and once the three wires from the Hall sensors are clearly identified, what device would you recommend:
The IRS 2332
Or
The MC33035
Pros and cons ?
Thank for explaining that differences to us,
Kind regards
霍西奥
欢迎您欢迎Horacio，
If the hall effects are employed then the MC33035 has to be used since it is specifically designed to process the hall effect signals.
Without hall effect, the IRS2332 circuit can be used, since it can work using external independent synchronizing signals from a 3 phase generator.
Both are good, but the hall effect design is the recommended one since it will provide higher efficiency for the motor rotation.
Hi Swagatam
I am looking to make a prototype dishwasher with variable temp using bldc motor do you have any plans or pcbs for this project ?
Hi Bindesh,
如果您可以详细解释整个程序和您的要求，那么我可能会尝试帮助！
wordpress@homemade-circuits.com.– can I send the details on this email ?
I would prefer discussing it through comments, so that it can be read by other visitors also. You can specify the main functional requirements, if it is possible I will try to solve it.
