Problems solved by technology

[0003] In the prior art, the way of overload operation is realized by adding a load to the output shaft of the motor, and the load has been set at the beginning of the motor test. When it is necessary to increase the load of the motor, it is necessary to Manually disassemble the load fixed on the output shaft of the motor, and then replace the heavy load. This assembly method is inefficient, resulting in low efficiency of the durability test of the motor.

Abstract

The invention discloses a three-phase brushless DC motor durability test bench, which comprises a base, a loading plate arranged on the base and an installation block arranged on one side of the loading plate, and the base is provided with a second A chute and a second chute, the bottom of the carrier plate is provided with a first slider that matches the first chute, and the bottom of the mounting block is provided with a second slide that matches the second chute. Two sliders, the base is provided with an electric push rod matched with the installation block, the installation block is provided with a first movable groove, and a counterweight plate is arranged in the first movable groove, and the distribution A plurality of installation grooves are arranged on the side wall of the weight plate, and counterweight blocks are arranged in the installation grooves; connecting holes are arranged on the balance plate, and connecting components are arranged in the connection holes; between the installation grooves and the counterweight With the mutual cooperation of the blocks, the weight of the counterweight plate can be increased at any time according to the needs, without the need to pull out the motor output shaft from the connection hole to connect a new counterweight plate, which improves the efficiency of the motor durability test and reduces the difficulty of the motor durability test.

Description

technical field [0001] The invention belongs to the technical field of motor detection, and in particular relates to a three-phase brushless DC motor durability test bench. Background technique [0002] The service life and reliability of the motor are directly related to the life and safety of the equipment using the motor. Therefore, the durability test of the motor is an essential link in the motor research and development process. [0003] In the prior art, the way of overload operation is realized by adding a load to the output shaft of the motor, and the load has been set at the beginning of the motor test. When it is necessary to increase the load of the motor, it is necessary to Manually disassemble the load fixed on the output shaft of the motor, and then replace the heavy load. This assembly method is inefficient, resulting in low efficiency of the durability test of the motor. Contents of the invention [0004] In order to overcome the deficiencies of the prio...
