Vehicle flat wire permanent magnet synchronous motor

Abstract

The invention discloses a vehicle flat wire permanent magnet synchronous motor. The motor comprises a base, a casing fixedly mounted at the top end of the base, a cooling fin fixedly mounted on the outer wall of the casing, and a plurality of connecting pieces fixedly mounted on two sides of the casing, and is formed by manufacturing stators in batches and then splicing the stators, so working efficiency is greatly improved, and production cost is reduced. integral processing difficulty is reduced, the T-shaped sliding strips, the T-shaped grooves and the first limiting rings are arranged, soinstallation of the flat copper coil and the multiple partition plates is completed, a complete stator structure is formed, operation is easy and convenient, installation efficiency of the flat coppercoil is greatly improved, structures such as the stable sleeve are arranged, and the service life of the flat copper coil is prolonged; the stator iron core can be well clamped in the transverse direction and the longitudinal direction, so that overall fixation is completed, the device can work normally, installation is easy and convenient, and splicing efficiency and stability of the stator structure in the operation process are greatly improved.

Description

technical field [0001] The invention relates to the field of permanent magnet motors, in particular to a flat wire permanent magnet synchronous motor for vehicles. Background technique [0002] The permanent magnet synchronous motor provides excitation with permanent magnets, which makes the structure of the motor relatively simple, reduces the cost of processing and assembly, and saves the collector ring and brush that are prone to problems, which improves the reliability of the motor operation; and because no excitation is required current, without field losses, increasing the efficiency and power density of the motor. [0003] With the development of new energy electric vehicle technology, the performance requirements for electric vehicle drive motors are getting higher and higher, and the power density requirements for drive motors are constantly increasing. Compared with other types of motors such as three-phase asynchronous motors and switched reluctance motors, three...

Problems solved by technology

[0004] However, the existing stator manufacturing and installation methods are relatively complicated, which affects the efficiency of mass production. When the flat wire is wound on the stator, it takes a lot of time and manpower, and it is also very difficult to install the stator on the casing after installation. Laborious, therefore, a stator structure that is easy to wind and install is required
