Slotless brushless grooved drum permanent magnet synchronous motor comprising special controller and rotary transformer

Abstract

The invention provides a slotless brushless grooved drum permanent magnet synchronous motor comprising a special controller and a rotary transformer, and relates to the field of motors. The slotless brushless groove drum permanent magnet synchronous motor with the special controller and the rotary transformer is provided, the motor comprises a motor shell, a motor rear cover and a motor front cover, wherein the motor front cover and the motor rear cover are fixedly connected with a front end and a rear end of the motor shell respectively, a rear boss is fixedly arranged at the position, closeto the center of a side wall of a front end, of the motor rear cover, a front boss is fixedly arranged at the position, close to the center of a side wall of the rear end, of the motor front cover, afront bearing is arranged at an inner end of a front boss, a rear bearing is arranged at an inner end of a rear boss, and a main shaft is rotationally arranged at an inner end of the front bearing. The slotless brushless groove drum permanent magnet synchronous motor is advantaged in that by using the slotless and brushless grooved drum permanent magnet synchronous motor with the special controller and the rotary transformer, overall structure complexity of the motor can be reduced, production is convenient, and working efficiency, working precision and the overload capacity of the motor are improved.

Description

technical field [0001] The invention relates to the technical field of motor design and manufacture, in particular to a slotless, brushless, slotted permanent magnet synchronous motor including a dedicated controller and a resolver. Background technique [0002] A motor is an electromechanical device that uses a magnetic field as a medium to convert electrical energy and mechanical energy. The relationship between the number of stator slots and the number of rotor poles in a motor is called pole-slot coordination. Different pole-slot coordination can change the winding factor and efficiency of the motor. , cogging torque and other attributes, which have a great influence on the performance of the motor. The number of slots of each stator and the number of poles of the rotor of a traditional disc motor are the same, which makes each stator and rotor equivalent to the motor with the same attributes, which cannot produce complementary performance between different stators, whic...
