Title:
PERMANENT-MAGNET SPEED REGULATING MOTOR AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/042051
Kind Code:
A1
Abstract:
Disclosed is a permanent-magnet speed regulating motor, comprising a motor base. An outer rotor assembly and an inner rotor assembly are provided on the two ends of the motor base along a length direction thereof by means of bearings, respectively; the outer rotor assembly comprises a first rotating shaft, and the first rotating shaft is provided with collector rings; a cylindrical iron core holder is provided at one end of the first rotating shaft which is located in the motor base; an outer rotor iron core and a plurality of sets of induction coils matched with the outer rotor iron core are provided in the iron core holder; output ends of the induction coils are connected to the collector rings; the number of sets of the induction coils is 3N (N is an integer), and the number of sets of the induction coils is greater than or equal to six sets; the number of the collector rings is 3N; each set of induction coils forms one three-phase potential, and there totals N three-phase potentials having completely identical phases.
