Example Embodiment

[0027] Such as Figure 1-7 As shown, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0028] Such as figure 1 As shown, an integrated motor drive system integrating a motor and a controller consists of a rotor assembly 1, a housing assembly 2, a stator assembly 3, a rear cover assembly 4, a rear housing 5, a rear cover 6, a control board 7, The driver board 8 is composed. Such as figure 2 As shown, the rotor assembly 1 consists of a shaft 1-1, a front deweighting ring 1-2, a rotor yoke 1-3, a magnet 1-4, a rotor sheath 1-5, a rear deweighting ring 1-6, and a tracking magnetic Steel 1-7 composition. The end of shaft 1-1 is milled with a concave surface, and the boss of the tracking magnet 1-7 is aligned with the concave surface of the end of shaft 1-1. The middle part of shaft 1-1 is milled with two symmetrically distributed flat key grooves, shaft 1-1 and rotor magnet The yoke 1-3 is connected by two ...

Abstract

An integrated motor driver system integrating a motor and a controller is used for a separation structure, which requires large installation space and is heavy in weight and high in cost, of an existing driver and a permanent magnet synchronous motor, an existing permanent magnet synchronous motor integrated structure has defects of low output power, cooling difficulty and the like. The integrated motor driver system comprises an enclosure assembly, a stator assembly, a rotor assembly, a rear end cover assembly, a rear shell, a rear cover, a control plate and a driving plate. Since the controller and the motor adopt an axial series structure, a connection part between the controller and the motor is greatly reduced, and the integrated motor driver system has the advantages of small size, light weight and the like. A cooling boss is milled on the rear shell of the system, a power tube of the controller is pasted on the cooling boss by a double-sided cooling adhesive, the power tube is tightly pressed by an L-shaped press plate and fixed on the cooling boss, cooling of the power tube of a driver is achieved by the rear shell, and the integrated motor driver system has the advantages of high heat dissipation and the like.

Description

technical field [0001] The invention relates to an integrated motor driver system integrating a motor and a controller, and mainly relates to the field of motors and motor drives. More specifically, it relates to an integrated motor drive system integrating a permanent magnet synchronous motor and a controller. Background technique [0002] With the advancement of industrial technology, motors, as executive components in the field of industrial control, are used more and more. The traditional DC motor is convenient and simple to control, but due to the existence of carbon brushes, the service life of the motor is seriously restricted. AC asynchronous motors are gradually replaced by new permanent magnet synchronous motors due to inconvenient speed regulation and low efficiency. Due to high efficiency and convenient and flexible control, permanent magnet synchronous motors appear more and more in the field of control. Usually, the permanent magnet synchronous motor system ...
