Brushless DC Motor Speed Controller - A simple, cheap, BLDC motor controller using readily-available components is described.

A simple, cheap, BLDC motor controller using readily-available components is described.
Most previously-published speed controllers for BLDC motors either (1) reduce the supply voltage across the motor by a linear or asynchronous PWM control method, or (2) require access to the individual coils of the motor to vary the coil drive, and involve either dedicated ICs or microcontrollers together with optical or back-emf rotor-position sensing arrangements. Here is a simple alternative, using what...
