DRIVERS FOR IRONLESS ROTOR D.C. MOTORS
Ironless rotor DC motors present characteristics highly desirable for speed and position servos. Due to the absence of iron there is no cogging, and the rotor has no preferred positions, phenomena which tend to deteriorate precision of a servo. Furthermore, their low rotor inertia improves the dynamics of the entire drive system.
This paper considers amplifiers for DC motors up to 1 kW output power. Speed or position servo loops are not dealt with.
