Abstract

The invention relates to a device for testing the constant thrust load of a continuous linear motor, belonging to the field of motor test and aiming to solve the problems of one-way measurement, complicated measuring process and poor precision of a tester which adopts loaded weights to test the constant thrust of the linear motor. The device for testing the constant thrust load of the continuous linear motor comprises a test platform, the linear motor, a magnetic powder brake, a direct current supply, a first synchronizing wheel, a second synchronizing wheel and a synchronizing belt, wherein the linear motor comprises a linear motor mover and a linear motor rotor and is arranged on the test platform and between the first synchronizing wheel and the second synchronizing wheel; one end of the test platform is provided with the magnetic powder brake, and an output shaft of the magnetic powder brake is fixedly connected with the first synchronizing wheel; both ends of the synchronizing belt are respectively connected with both ends of the mover of the linear motor, the mover of the linear motor drives the first synchronizing wheel and the second synchronizing wheel to rotate by the synchronizing belt, and the direct current supply provides the magnetic powder brake with direct current. The tester is used for measuring the constant thrust of the linear motor.

Description

technical field [0001] The invention relates to a constant thrust load testing device for a continuous linear motor, which belongs to the field of motor testing. Background technique [0002] The existing linear motor constant thrust loading test device such as figure 1 and figure 2 as shown, figure 1 and figure 2 The schematic diagrams of the testing device for two directions of the linear motor are shown respectively. Through the pulley 10 and the transmission rope 11, the own weight of the weight 12 is added to the mover 2 of the linear motor to form a unidirectional pulling force to be loaded on the linear motor. Constantly changing the weight of the weight 12, when the linear motor reaches a constant speed, the braking thrust of the linear motor is equal to the weight of the weight 12, thus obtaining a constant thrust of the linear motor. The disadvantages of this test device are: (1) when testing the loading thrust, it can only measure in one direction and one w...
