Embodiment 2

[0042] A permanent magnet synchronous motor with a limited rotation angle is composed of a base 1, a permanent magnet 2, front and rear end covers, front and rear bearings, inner and outer rotating shafts, an armature core 6 and an armature winding 7.

[0043] The armature core 6 is made of stacked high-permeability silicon steel sheets with armature slots. The armature winding 7 is made of high-conductivity materials and embedded in the armature slots of the armature core 6. The winding armature core 6 is shrunk on the outer shaft made of aluminum alloy through interference fit, and the outer shaft and the inner shaft made of No. 45 steel are connected by hinged hole bolts. The overall composition The motor rotor part and the outer shaft part are made of aluminum alloy, which can reduce the weight and moment of inertia of the motor rotor.

[0044] Machine base 1 is made of No. 10 steel material. On the inner circle of machine base 1, there are dovetail grooves with twice the ...

Abstract

A permanent magnet synchronous motor with a limited rotation angle belongs to the technical field of synchronous motors, and comprises a base 1, a permanent magnet 2 and an end cover 3, a bearing 4, arotating shaft 5, an armature core 6 and an armature winding 7; the base 1 is connected with the end cover 3; the permanent magnet 2 is mounted on the inner side of the base 1, and the base 1, the permanent magnet 2 and the end cover 3 integrally form a stator; the rotating shaft 5 is connected with the end cover 3 through the bearing 4; the armature core 6 sleeves the rotating shaft 5; a grooveis formed in the armature core 6, the armature winding 7 is installed in the groove, and the rotating shaft 5, the armature core 6 and the armature winding 7 integrally form a rotor. The armature core6 is located in the permanent magnet 2, and a gap is arranged between the armature core 6 and the permanent magnet 2. The motor is small in size, high in torque density, low in rotating speed and high in efficiency.

Description

technical field [0001] The invention relates to a limited rotation angle permanent magnet synchronous motor, in particular to a low speed, high efficiency and high torque density limited rotation angle motor. Background technique [0002] The design and development of bionic fish is the crystallization of the integration of many high-tech disciplines, and it is an integrated design system of mechanics, optics, electricity, computer technology, automatic control, material technology, sealing technology and fluid mechanics. Developed countries such as Europe, America and Japan started earlier in the field of theoretical research and design of bionic fish. As a rising star, China has also achieved fruitful results in the research of bionic fish. However, compared with real fish, bionic fish still has a certain gap in swimming speed, maneuverability and swimming efficiency, and more in-depth research on the theory and system design of bionic fish is needed. [0003] The main dr...
