specific Embodiment approach 1

[0014] Specific implementation mode one: the following combination figure 1 and figure 2 This embodiment is described. In this embodiment, a winding method for unequal turns of a compact mechanical arm joint motor is described. The compact permanent magnet brushless motor includes a hollow multi-pole permanent magnet rotor and a stator embedded with a Hall element. , the stator includes a stator core, and a plurality of stator slots are arranged on the stator core, and three Hall elements 1 are embedded in the stator slots in a three-phase symmetrical manner;

[0015] The method of winding the three-phase symmetrical winding in the stator slot is: the number of turns of the winding wound in the stator slot where the Hall element 1 is located is less than the number of turns of other stator slots, and the number of turns reduced is determined by the size of the Hall element 1. And the windings of the stator slots where the three Hall elements 1 are located are arranged symmet...

Abstract

The invention discloses a winding method of an unequal-turn coil of a compact type mechanical arm joint motor, and belongs to the field of motors. The problem that the torque of the motor is fluctuant since a Hall element is directly embedded in the existing motor. The compact type permanent brushless motor comprises a hollow multi-pole permanent rotor and a stator having embedded Hall elements; the stator comprises a stator iron core, a plurality of stators slots are formed on the stator iron core, three Hall elements are embedded in the stator slots in a three-phase symmetric mode; the method of winding the three-phase symmetric coils in the stator slots is as follows: the coil turn wound in the stator slot in which the Hall element is located is less than the turns of other stator slots, and the reduced number of the turn is decided by the size of the Hall element, and the coils of the stator slots in which three Hall elements are located are symmetrically arranged.

Description

technical field [0001] The invention relates to a special winding structure of a high power density permanent magnet brushless motor for a space manipulator, belonging to the technical field of motors. Background technique [0002] The space robotic arm is an important device necessary for space engineering, assisting astronauts to complete high-precision transportation and maintenance work. The design requirements of the mechanical arm are high strength, high reliability, flexible work and light volume and weight as possible. Electromagnetic devices are essential in the manipulator drive system. Compared with hydraulic drive and other common drive methods for ground manipulators, electromagnetic drive has great advantages in the space field. Therefore, as far as the current development of the space field is concerned, other countries with advanced space science and technology have adopted electromagnetic drive methods to solve the drive problem of space manipulators.
