RioRand 380W 6.5-50V 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

used an excellent guide from "thrifty tool shed" on YouTube for this retrofit. I mounted mine a bit differently and used a reemer to create a few small vent holes for the heatsink. I also had to file a little off the corner of the heatsink to make it fit where I put it. There are some plastic "ribs" that need to be cut out as well as one screw mounting hole trimmed to clear a capacitor. I only retained use of the side knob and main trigger, no need for the turbo button. I also added a 20A inline fuse. the response takes a bit more trigger travel to kick the motor on, but max speed is still there. worked absolutely amazing for drying my car and blowing leaves. No issues with heat so far and after using it for 20min non stop full blast, battery light still at max bars. this is a very cost effective way of fixing a broken Ego 56V blower, as long as you can solder and make a few plastic and filing tweaks you're good to go.

used to power an ego blower. It blew out the Ego fan motor but prob because I had it wired to run at full blast with trigger pulled (basically turbo mode) all the time. And I was using it as such. whereas the ego setup only lets you run turbo for a little bit before it throttles back, so prob why it burned the motor out. Otherwise it worked well for Ego blowers and you can use it for that. I did swap capacitors for higher voltage higher capacitance ones.

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.

Works well. It does get hot so I'm using a small fan. Running a rad fan on one and coolant pump on the other.
