Abstract

The invention provides a moment motor structure. The structure comprises an outer shell, a motor shaft, a motor stator and a motor rotor. A front end surface of the outer shell is installed with a bearing pedestal. A rear end surface of the outer shell is installed with a bearing support seat. The structure is characterized in that a bottom of the bearing pedestal is installed with a group of angular contact ball bearings; the motor stator is fixed into the outer shell through a stator end cap; the motor shaft is installed with the motor rotor, a rotor fixing sleeve and a rotor fixing end cap; a deep groove ball bearing is installed in an inner hole of the bearing support seat; the inner hole of the bearing support seat is provided with a circular groove and a rubber ring is installed in the groove; an inner ring of the deep groove ball bearing is provided with a taper sleeve; and an outer section of the bearing support seat is fixedly installed with an encoder. In the invention, from aspects of a moment motor structure design and selection of a standard component, the structure is simple and reliable, the motor structure can be assembled without a special technology and a tooling and the structure is suitable for single one production and a small quantity of motor production.

Description

technical field [0001] The invention relates to the technical field of torque motors, in particular to a torque motor structure. Background technique [0002] At present, electric motors have been widely developed as power sources. At the same time, various standardized and serialized stator and rotor sub-package products have appeared on the market for users to choose, so as to meet the requirements of different industries and special working conditions. Most of the finished motors on the market are assembled on the production line, which requires complete tooling equipment to complete some complicated assembly processes, such as avoiding the stator and rotor being attracted together by magnetic force during the assembly process, and adjusting the clearance and preload of the bearing at the same time And loading requires reliable data and implementation methods. [0003] However, users who choose separate motors to meet special working conditions or save costs need to des...
