RioRand380W 5-50V PWM DC Brushless Electric Motor Speed Controller with Hall-Less

es funcional y cumple con su cometido sin embargo al arranque tiene un pequeño retraso de 1 segundo

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.

Although unit is now a improved version of the one shown by Amazon (see attached) Unit works great.Remember to pull the 2pin header off (next to the Blue speed POT) for external voltage speed control.Use the BRAKE terminal to stop (the STOP terminal appears to do nothing)FWD/REV works great. Speed control is really throttle control. Need to throttle up if motor is under-load to keep same RPM. Hope a tach output is added. Just works so so smoothly! Just bought another.

The most handy brushless test controller! Strong enough to quick test my brushless ebike motors without a hall sensor connection. Perfect little brushless motor controller and throttle tester. Note that it will allow some motor rotation with standard hall output throttle if not using the on board potentiometer. Use a pull down resistor on the external hall throttle or just use an external potentiometer.

There are 3 problems with this product and I ordered twice.1. Both have defect on small capacitor (100uF) at the edge, the first one one lead detached from the board and the second one totally detached. I have to resoldered and replaced. You can see from the pictures here, replaced capacitor (1)2. When I tested the 1st one it is fine but too hot, found out heat sink is badly installed and surface of all the transistors are not flat. No silicone grease on it, i have to add it.3. For the 2nd board, it runs rough and found out there is missing/displaced resistor BH (the feedback B). See the close up picture.It is cheap but don't expect to be used immediately. And how amazon handle this board probably the cause of detached capacitor 100uF at the edge.
