Abstract

The invention relates to a coreless permanent magnet linear motor with a cooling structure, a manufacturing mould for a winding coil thereof and a machining process for the winding coil and belongs to the technical field of linear motors. The coreless permanent magnet linear motor with the cooling structure is used for solving the radiation problem of a coreless permanent magnet linear motor. Stators of the coreless permanent magnet linear motor with the cooling structure are mirror-symmetrically arranged at the two sides of a rotor, wherein the rotor comprises an armature winding and a cooling pipeline; the cooling pipeline is composed of an upper pipeline, a lower pipeline and two connectors; the upper pipeline passes through an arc-shaped through hole which is formed on the upper end part of the armature winding; and the lower pipeline passes through an arc-shaped through hole which is formed on the lower end part of the armature winding. The manufacturing mould for the winding coil of the coreless permanent magnet linear motor with the cooling structure is composed of two winding shape-fixing components, a coil dislocation moving component and two base plates. The machining process for the winding coil by using the manufacturing mould for the winding coil is used for realizing the dislocation of upper and lower coil edges of the winding coil and preventing a winding from falling into pieces. The machining process provided by the invention is suitable for the coreless permanent magnet linear motor.

Description

technical field [0001] The invention relates to a coreless permanent magnet linear motor with a cooling structure and a manufacturing mold for its winding coils and a processing technology for the winding coils, belonging to the technical field of linear motors. Background technique [0002] Coreless permanent magnet linear synchronous motors are widely used in high-speed and high-precision small and medium-sized CNC machine tools, electronics manufacturing industry, and micro-nano technology manufacturing. It can achieve high positioning accuracy and system resolution. Generally, the thermal resistance of the ironless linear motor is large, and the heat generated by the copper loss of its winding is dissipated to the external system through heat transfer. In the field of ultra-precision machine tool processing and micro-nano technology manufacturing, thermal expansion will adversely affect the accuracy of the motor itself and the entire system. Adding a cooling structure i...
