The monopole brushless rotary transformer equipment disclosed by the invention solves the problems that the traditional rotary transformer stator design method can not realize automatic mechanical winding and hand insertion is required to be adopted, improves efficiency, reduces costand meets industrial batch production and customer requirements.

Description

technical field [0001] The invention belongs to the technical field of servo motor control, and in particular relates to a single-pole brushless rotary transformer device used as a position feedback element for a servo motor working in harsh environments. Background technique [0002] Unipolar brushless resolver (hereinafter referred to as brushless resolver) is a signal motor with strong environmental adaptability and reliable operation. It is widely used in servo control links in harsh occasions as position feedback components. It is used in servo motors for robots and injection molding machines. Servo motors, textile machinery servo motors, and military servo motors can all be used. [0003] The size of the output voltage of the resolver changes with the angular displacement of the rotor, and the voltage amplitude of the output winding has a sine and cosine function relationship with the rotor angle. The position angle of the rotor is obtained by demodulating the output ...

Problems solved by technology

[0008] In view of the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a single-pole brushless resolver equipment with 20 slots in the rotor core and 11 slots in the stator core, so as to solve the problem of rotor core in traditional brushless resolver equipment. The 20 / 24 slot structure matched with the slots of the stator core, the stator side cannot realize automatic machine winding, and must be manually off-line, which has low efficiency and high cost, and cannot meet the problems of industrial mass production and customer needs.
