Review: Worked great for me, but WATCH OUT - many questions/answers are for another product - Note - many of the questions/answers displayed for this item are actually for the Hall Sensor version so please be careful and don't assume all those answers apply to this module. This listing is for the "Hall-less" version, meaning it's for controlling a 3-phase DC motor that only has 3 wires and does NOT use hall sensor monitoring. Some errors I noted in the Q/A section: - some Q/A indicate the module has "soft-start" - it does not, but see my easy hack to add it below* - some say to "remove the jumper" to use the external analog speed control - there is no jumper on this module, just be sure to set the on-board speed pot to zero (full ccw) - some say this module will not work with a Hall-less motor - that is WRONG, it is specifically designed to work with hall-less motors. - there are several different wiring diagrams shown in the listing, but the one that has pictures of the motor and power supply is what I used and seems to be correct. I used this controller to operate the fan motor from an EGO leaf blower that was trashed because the internal controller died. My fan motor has 3 leads - red, blue, and yellow, which connect to the controller terminals red to red, blue to blue, and yellow to green. I'll use this fan blower with some 18v cordless tool batteries as a sweeper in my shop and patio, and 18v yields plenty of air flow for that purpose. * I made a simple modification to perform a soft-start function, using a 470uf capacitor and a 1k resistor (see photo and video). Some experimenting proved that the external potentiometer speed control reaches maximum motor speed at about 4.6v, which can be achieved by placing a 1k resistor from the 5v terminal to the analog speed input. By adding the capacitor, the voltage on the speed input slowly rises when power is applied, so that the motor speed ramps up from zero to full speed in about a second, greatly reducing the strain on the power supply, controller, and the motor. If you want a slower start-up you can increase the size of the capacitor, but leave the resistor at 1k. If you increase the resistance above 1000Ω the motor will never reach full speed.
Review: Sweeeeet! - I have been saving some 3 phase motors....BLDC and PMSM type, for a long time. This board is awesome. I can easily drive 24V PMSMs (see video). It stays winter cool to the touch! I want to stress that I'm no where NEAR the 380W limit of this thing. I hope another reviewer can attest to the max capabilities. But if you're looking at driving small to medium size BLDC or PMSM, this is a great option. I was going to upload a nice video of a gorgeous BLDC from a tape drive, but it's enormous. I'll just upload pictures...It drove a nice fat motor too (see photos). For anyone wondering, you can run hard drive motors, too. Looking forward to using these for some projects to reclaim bad or old hard drives! I actually tested this on a WD raptor spindle and some other seagate disk spindles. Works great. You just need to figure out which motor contact is the center tap. Remove this from what you connect. The remaining three should connect to UVW. It will spin just fine without a common terminal. Definitely usable. I didn't try the PWM control feature yet. I've been using the onboard potentiometer to control speed. If you want to use PWM or DC voltage for this, remove the jumper. It's not clear, but I think that's what it does. Connection a pot as shown in the photos gives you DC voltage control (like the onboard pot), and pumping a square wave into it instead will give you PWM control. The way the PWM input works, it probably just low-pass-filters the input signal. If it's PWM, it gets converted to DC voltage. If it's DC voltage, it goes through the filter the same way. If you want to run a BLDC or PMSM motor by variable speed (without speed feedback) this board is going to do it for you.

## Features

- 1.Three-Phase DC Brushless Sensorless Motor Controller: Works normally even without Hall sensors on the motor. It’s a high-power (300W) three-phase high-speed DC brushless sensorless controller with wide DC voltage range (5-50V). Speed control supports three signal inputs: PWM signal, PLC 0-5V analog signal, and 1-4.2V Hall throttle input.
- 2.The brushless sensorless motor controller has fast acceleration response. When powering on and starting at full throttle, the instantaneous starting current is very high—leave a safety margin, and do not perform direction reversal startup at full throttle under high voltage and high power. Additionally, braking causes significant impact: do not brake when the motor runs at full speed under high voltage; forced operation may damage power transistors and chips. It is recommended to reduce the speed throttle to 50% or below before performing these operations.
- 3.Reversing the positive and negative terminals of the power supply on the main board will cause permanent damage to some on-board chips (even for a few seconds under high current). Do not connect motors with significantly mismatched voltage, current, or power relative to the driver module.
- 4.During normal operation, the motor output has sampled overcurrent protection. Due to the module’s high power and current, do not manually short-circuit the module when it is not working properly—short-circuiting may burn wires or blow transistors. For the first wiring test, use low current and low voltage; only after confirming it works properly, switch to high current and high voltage. Never let high voltage come into contact with components on the board.
- 5.The brushless sensorless controller delivers more stable performance. All interfaces use terminal blocks, it comes with a standard heat sink, and has a built-in speed potentiometer—it’s ready to use right after powering on (once wired correctly).

## Questions & Answers

**Q: Can this be bumped up to dealing with 80v? could I simply change the capacitor, or is 60 limited by the chip?**
A: I ran it at 60 but the built in transformer can’t bring reference voltage to right v with higher input voltage

**Q: Dose this work on a electric  scooter?**
A: I used two with hover board motor hubs at 60v in a go kart. It was pretty fast!

**Q: Is there a data sheet for the whole board, i need to know how it works and it building blocks. A deep review of the chips like JY01 and its mosfets.**
A: not in this package, not at all

**Q: Does the pot have to be turned to zero before the brake is activated?  Or will toggling the brake disable the drive?  Can brake act as on/off switch?**
A: 1. No need to zero

2. Yes, braking (brake) has the highest priority

3. It can be used as on-off function, but not equal to on-off

### ⭐⭐⭐⭐ It works for my application.
*by T***G on November 29, 2025*

Used it to test power tool brushless dc motor and it performed as expected. Package could be better with some pads or foam; it is just a plastic bag!
