Embodiment Construction

[0025] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.

[0026] A semi-open compact self-contained torque motor. The motor is a self-contained structure, which includes a casing assembly 1, a magnetic steel 2, a shaft sleeve 3, an armature winding 4, a brush holder 5, and a brush 6. Bearing 7, inner lock nut 8, outer lock nut 9 and lead wire 10. The casing assembly is a semi-open structure with one side closed and one side open. The casing assembly has an inner cavity, bearings, bushings, armature windings, inner lock nuts, outer lock nuts, magnetic steel, brush holders and brushes. located in this lumen.

[0027] The casing assembly 1 includes a casing outer ring 1-1, a casing shaft 1-2 and a casing flange 1-3, and there are multiple casing flanges. In this embodime...

Abstract

The invention relates to a semi-open compact integral torque motor, comprising a housing assembly, a magnetic steel, a shaft sleeve, an armature winding, a brush holder, a brush, a bearing, an inner lock mother, an outer lock mother and a lead wire, wherein the housing assembly comprises a housing outer ring, a housing shaft and a housing flange. As that bear of the invention is directly installedin the inn cavity of the shaft sleeve, the function of the general fully closed integral structure is completed by the semi-open mode, and the mechanical performance of the motor is greatly improvedin the limited space and the weight range. The invention has the advantage of less parts, high reliability, compact structure and wide application range.

Description

technical field [0001] The invention relates to the technical field of permanent magnet direct-current torque motors, in particular to a semi-open compact self-contained torque motor used in a lightweight high-precision drive system. Background technique [0002] DC torque motor is one of the more important torque motors. Its main features are small size, high power density, simple control and fast response. In some high-precision torque drive systems, the motor is required to have good mechanical properties, short response time, and small dead zone under low-speed conditions. At the same time, there are high requirements on the limited size and weight of the motor. [0003] Ordinary self-contained permanent magnet DC torque motor is a fully enclosed structure, with a large increase in size and a large loss in mechanical properties. It cannot reach a high level in terms of size, peak torque, torque fluctuation, and static friction torque. There are certain difficulties in ...
