Abstract
A PM line-start motor, preferably motors having a power of at least 5 kW, and a switch-on method therefor are provided. The motor includes a rotor and a stator having a stator winding designed as a pole-reversible rotary field winding. With the aid of the pole-reversible rotary field winding, the regenerative braking torque generated during the asynchronous high-run operation can be avoided, preferably by use of a sequence controller to control the changeover of the pole-reversible rotary field winding in the run-up phase.
