High-power suspension type permanent magnet direct drive motor

Abstract

The invention discloses a high-power suspension type permanent magnet direct drive motor, relates to the field of motors, and aims to solve the problem of difficulty in assembly and disassembly. The high-power suspension type permanent magnet direct drive motor is characterized by comprising a stator base and a driving rotor support, wherein a plurality of stator iron cores are mounted on the inner circumferential surface of the stator base at equal angles, each stator core is provided with a motor winding, and a plurality of permanent magnet poles are installed on the outer circumferential face of the driving rotor support at equal angles; the driving rotor support comprises a center sleeve, a connecting ring sleeve and a connecting part, the stator base is of a two-end-penetrating structure, and supporting end covers are arranged at the two ends of the stator base respectively; the supporting end covers are provided with inward turning parts, the inward turning parts are located in the connecting ring sleeve, and a rotary supporting mechanism is arranged between the inward turning parts and the connecting ring sleeve. According to the high-power suspension type permanent magnet direct drive motor, the assembly and disassembly convenience is effectively improved.

Description

technical field [0001] The invention relates to the field of motors, more specifically, it relates to a high-power suspension permanent magnet direct drive motor. Background technique [0002] The permanent magnet synchronous motor is mainly composed of stator, rotor and end cover. The stator is made of laminations to reduce the iron loss generated during the operation of the motor. It is equipped with a three-phase AC winding, which is called an armature. The rotor can be made in solid form or pressed from laminations with permanent magnet material on them. [0003] The Chinese Patent Publication No. CN107086686B discloses a built-in permanent magnet motor rotor. Its technical characteristics are: it includes a traditional built-in permanent magnet motor rotor core, an alternating pole built-in permanent magnet motor rotor core, a rotating shaft and a permanent magnet. A traditional internal permanent magnet motor rotor core is arranged on both sides of the alternating pol...

Problems solved by technology

[0004] The technical solution disclosed in the above-mentioned solution uses the rotating shaft as the torque output end. In practical application, it is found that when mining machinery and large-scale hoisting machinery require high-power and large-volume motors to be installed in a suspended manner, it is not only necessary to add large-scale motors Shaft device, and it is necessary to connect the output shaft and input shaft between the gap between the motor and the equipment, and there is a problem that it is not easy to install and disassemble
