I am in urgent need of a motor speed controller circuit diagram for a 36V scooter. The motor specifications are 36 V at 800 Watts. I would greatly appreciate it if some could post a suitable diagram for this.
use google, switch to image search and type in PWM
you will find tons of circuits that can easily be adopted for your motor. i would go with big hexfet since 800W motor will draw over 20A and peak current will go much higher.
