24V Brushless DC Motor Kit with Controller – High Speed High Torque BLDC, Low Noise Electric Motor for E-Bike, Scooter, RC Car, Drone & Robotics Applications

I'll be the first to say when I saw a motor advertised as brushless but with only two wires, I didn't believe it would actually be a brushless motor. So I opened it up and surprisingly it is a brushless motor with an internal controller. The motor is fairly quiet and it works quite well. The speed can be controlled by varying the input voltage. The one I received didn't kick on until 8V but it has a pretty nice speed range between that 8V and 24V. The highest amperage it pulled was about 2.54A. The casing has a nice finish and it is quite sturdy (opening it up wasn't easy). The shaft is 1/8" (3.15mm) which works well with commonly available pulleys and adapters. It has fairly decent torque for its size. The controller board has an unused PWM input so I'm very tempted to play around a bit more with this motor to see if I can use a PWM speed control with it. It does work as advertised as it is so I'm only reviewing it on an as is basis. All in all, it's a decent DC brushless motor, it works quite well and has a nice speed range. I'm pretty pleased with it.

I've been working with brushless motors in the RC market for over a decade now. This motor completely stumped me, and I still don't know what to think about it. This is documented as an 8-24v 10000rpm at 24v(416kv) brushless inrunner. The esc is built into the rear of the housing, which is where I was confused with this setup. There is only a positive and negative input for this motor. There isn't a signal or pwm wire to control the esc speed. The motor I received either doesn't work or needs this signal wire to run. There's no documentation that I can find to assist with this. Everything I've found online shows this motor with more wires. I just don't know about this...

It would be nice if there was more information included about the motor's ratings on the motor itself for reference, since only the seller's name is marked on the motor body. At 24V the motor draws 0.27A or 6.5W when unloaded, though this rapidly increased as I attempted to stop the motor shaft. This seems to match the table shown in the product images. The motor wasn't too loud and the noise it made wasn't an annoying pitch. I'm very skeptical of this being a practical choice for any kind of E-bike, but should be great for an RC car. As near as I could measure with calipers the motor shaft is the expected 1/8". While the description states "Complete Kit with Controller", since only the motor was in the package I believe this refers to the control circuitry integrated into the motor itself. This allows it to be run simply off of a DC voltage like a brushless DC motor without needing an external BLDC controller. It also seemed to work with a PWM'd DC input, but I'm not sure if this is recommended.

This motor burnt out immediately. I first powered it briefly with 8.4V just to test it and it ran fine. I then used 18V, which is well within the stated 8.5–26V operating range. It ran for only a few seconds and then completely stopped working. It would not run again. This motor is advertised for RC cars, scooters, and e-bikes. However, this is a low current (approx. 5–30 watts) 2-wire direct DC brushless motor with a built-in controller. It’s designed for single-direction, light-load applications and not vehicle propulsion. Given how quickly it failed and how misleading the listing is about its intended use, I do not recommend this motor.
