Control system for synchronous motor, has controller and/or control unit adjusting high longitudinal axis current, where rotor is engaged with preset rotation angle, which is compared with initial rotor angle

摘要

The system has a rotor with rotor poles and a stator with stator poles. A phase coil is connected with the stator pole and a controller for delivering a current instruction signal, which consists of an instruction signal for a longitudinal axis current aligned with the longitudinal axis of the rotors and an instruction signal for a transverse axis current aligned with the transverse axis of the rotor. The controller and/or a control unit adjusts high longitudinal axis current, where the rotor is engaged with a preset rotation angle, which is compared with the initial rotor angle.
