Disc type transverse flux permanent magnet brushless motor and method

Abstract

The invention provides a disc type transverse flux permanent magnet brushless motor and a method. The motor comprises two stator discs and a rotor disc, wherein the two stator discs are symmetricallydistributed on two sides of the rotor disc, the rotor disc is connected with a rotating shaft, two groups of permanent magnets distributed along the circumference are distributed on the rotor disc andare respectively called as an inner permanent magnet group and an outer permanent magnet group along the radial direction, each group comprises a plurality of permanent magnets with N poles and S poles arranged in a staggered manner along the circumferential direction, polarities of the upper and lower permanent magnets in the radial direction are opposite, each stator disc is composed of a plurality of stator iron cores which are uniformly distributed along the circumferential direction, each stator iron core comprises a C-shaped iron core pole body, a fan-shaped iron core pole shoe and an armature winding which is wound on a C-shaped iron core arm. The motor is advantaged in that industrial robot servo PMSM types are expanded, motor torque density is improved, the axial length of the motor is reduced, the motor can be flexibly applied to more occasions, the weight of a motor rotor part is greatly reduced, the rotational inertia of the motor is reduced, and a torque inertia ratio ofthe motor is improved.

Description

technical field [0001] The disclosure relates to the technical field of motors, in particular to a disc-type transverse magnetic flux permanent magnet brushless motor and a method thereof. The servo permanent magnet synchronous AC motor is suitable for industrial robots requiring small volume. Background technique [0002] Industrial robots are high-tech equipment that integrates several disciplines. They have broad application prospects in the field of intelligence and have developed rapidly in recent decades. Industrial robot technology has a high degree of automation and can be used flexibly. At the same time, it has strong anti-interference ability and can be competent for large Most production environments can replace human physical and mental work to a certain extent. The four major components of industrial robots are: body, servo system (including servo drive and servo motor), reducer, and controller. The cost of these four major components accounts for 22%, 24%, and ...
