Running up and pulling into step of PM line-start motors with surface-mounted…

Permanent magnet (PM) synchronous motors with starting cage, already developed in the 1960s for variable-speed textile drives, become increasingly important as energy-efficient PM line-start motors. Differing from the standard design with integrated magnets, a rotor design with surface-mounted magnets is presented. In the planning and design phase of drives with PM line-start motors, the simul…
