Abstract

The invention discloses a single-winding multi-speed motor pole-changing mechanism, which comprises a pole-changing shielding fixing seat assembly, a pole-changing assembly and a three-phase excitation slider assembly. The pole-changing assembly consists of a pole-changing shielding guide rail, three Phase inner lead-out terminal, three-phase inner transfer block, three-phase outer transfer block and three-phase outer lead-out terminal. It consists of a plate and a three-phase lead-out fixed cover. The single-winding multi-speed motor pole-changing mechanism reduces the axial space size of the motor, so that the motor can realize three-speed pole-changing in a limited space, because the pole-changing integrated slider slides along the pole-changing shielding guide rail to change poles The motor conversion can be realized by doing it inside the fixed circle. By cooperating with the convex end on the three-phase inner adapter block and the three-phase outer adapter block and the concave surface at the bottom of the three-phase copper plate frame, a pole-changing speed positioning can be realized. Improve pole-changing motor efficiency.

Description

technical field [0001] The invention relates to the technical field of pole-changing motors, in particular to a pole-changing mechanism of a single-winding multi-speed motor. Background technique [0002] The speed regulation of known pole-changing motors is generally achieved by changing the winding connection, and changing the series-parallel relationship of the motor windings through external switches. However, due to the complex structure, it is inconvenient to change the motor, and the efficiency of known pole-changing motors is lower than that of conventional general-purpose motors, so it cannot meet the requirements of users. Contents of the invention [0003] The purpose of the present invention is to provide a single-winding multi-speed motor pole-changing mechanism, which can reduce the axial space size of the motor, so that the motor can realize three-speed pole-changing in a limited space. The sliding of the guide rail is carried out in the pole-changing fixed...
