Understanding Electronic Motor Drives
drive controls the speed, torque, direction, and resulting horsepower of a motor. Dc drives typically control a shunt-wound dc motor, which has separate armature and field circuits. Ac drives control ac-induction motors and, like their dc counterparts, control speed, torque, and horsepower

Simplifying Motor-Control Feedback Loops (epn)
BLDC DMC system based on a microcontroller or DSP tailored for high-speed signal processing.The challenge for the designers of the DMC feedback loop is to find the right optimised point in the trade-off between precision and cost. Optical encoders meet the precision targets, however at a price

Sinusoidal Control of PMSM Motors with dsPIC30F DSC
by the DSP engine. The firmware is written in 'C' language, with some subroutines in assembly to take advantage of the special DSP operations of the dsPIC30F. The dsPIC30F Motor Control family is specifically designed to control the most popular types of motors, including AC Induction Motors (ACIM

and motor-specific part of the problem, trajectory calculation and servoloop control, is now just a software option on a high-speed DSP or microprocessor-based engine. And while the motion amplifier is still motorspecific, it, too, swaps easily with the motor. Motion-control systems share similar core elements
