Abstract :
This paper investigates the control principle of slotless micro permanent magnet synchronous motors (PMSM) for high-performance and high-speed applications. The control system of a micro PMSM without current control loops is analyzed based on the parameters of the micromotor. A test system for a 6-mm micromotor was built based on advanced DSP controller TMS320F2812. In this system, the relation between sampling frequency and current harmonics in the high speed is discussed, and the estimation of rotor position and speed is briefly introduced.
