[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor ... provide all that is needed to read the encoder, control the motor rotation and listen on the ‘stepper ...
MRS Electronic has introduced the Motor Controller 5 A CAN 32-bit, an advanced, compact motor controller designed for precise DC motor control in vehicles ...
Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control ... both motor current (think: shunt resistor) and rotor position (think: encoder).
