Method for governing synchronous running of electronically commutated motors involves each stator with stator windings of motor that are arranged with current feeding arrangement and current in all motor are commutated at same time

摘要

The method involves electronically commutated motors (22,24,26) each with a stator having a stator winding (40,42,44), a permanent magnetic rotor (28,30,32) and motor arrangement for the rotor position and rotor position signal (H1,H2,H3). The stator winding of the motor is arranged with a current feeding system (46) and the currents in all the motor are commutated at the same time. An independent claim is also included for the arrangement of the electronically commutated motors.
