A motor resistive rotor position detection device and method

Abstract

The invention discloses a motor resistance type rotor position detection device and method. By fixing a strip resistance at one end of the stator, both ends of the strip resistance are in contact with the inner wall of the stator. One end of the conductive sheet is aligned with one end of the strip resistance along the axial direction of the stator, and one end of the rotor is fixed with three contact wires arranged in an equilateral triangle. The ends of the three contact wires are insulated and contacted. Only one end of each contact wire can be in contact with the conductive sheet. Using the change of the contact position between the contact wire on the rotor and the strip resistor on the stator during the relative rotation, the partial contact of the strip resistor is realized, so as to obtain different connections. The invention can greatly simplify the complexity of traditional motor position detection, has a simple structure, and can greatly reduce product manufacturing costs; it solves the problems of complex wiring and low precision for motor detection in a narrow space.

Description

technical field [0001] The invention belongs to the technical field of motor detection, in particular to a motor resistance rotor position detection device and method. Background technique [0002] In recent years, my country's motor technology has developed rapidly. With the in-depth study of artificial intelligence, precision manufacturing and other fields, the requirements for manufacturing accuracy, durability and detection methods of driving devices or components have also increased significantly. Despite this, China has achieved certain results in motor R&D, manufacturing, testing and maintenance, but in the application field, especially in terms of high-end enterprises and market share, there is still a long way to go from the international advanced level. Motor is an important part of high-end intelligent equipment such as robots. Its unique ability to output multi-degree-of-freedom torque greatly reduces the complexity of traditional mechanical transmission mechanis...
