Cooling waterway automatic switching device for motor test

Abstract

The cooling waterway automatic switching device for the motor test comprises a circulating waterway device and a control device, and the circulating waterway device comprises a high-temperature water tank, a low-temperature water tank, a first electromagnetic valve, a second electromagnetic valve, a first water pipe, a second water pipe, a third water pipe, a fourth water pipe, a fifth water pipe, a sixth water pipe and a seventh water pipe. A water outlet of the high-temperature water tank is connected with a P port of the first electromagnetic valve through a fourth water pipe; an A port of the second electromagnetic valve is connected with a water return port of the high-temperature water tank through a third water pipe; the control device comprises a motor controller, an electromagnetic valve driver, a first low-voltage power supply and a second low-voltage power supply; the motor controller outputs different signals to the electromagnetic valve driver according to different motor rotating speeds, the electromagnetic valve driver carries out corresponding driving control on the first electromagnetic valve and the second electromagnetic valve according to the obtained signals, linkage of the working condition of the motor and the cooling water channel is achieved, and the working efficiency of the motor is improved. And rapid and automatic switching of high-temperature and low-temperature cooling water of the motor is realized.

Description

technical field [0001] The invention relates to the field of physics, in particular to a motor test, in particular to a cooling water circuit automatic switching device used for the motor test. Background technique [0002] During the motor test, it is necessary to supply high-temperature water or low-temperature cooling water to the motor according to the test conditions. Due to the complex test conditions of the motor and the extremely strict requirements for the test environment, the cooling water switching device in the prior art cannot achieve high frequency Switching, the switching speed is slow, the test time is long, and the degree of automation is low. The technical solutions in the prior art are as follows: [0003] Option 1: Manual switching, the tester observes the working conditions of the motor and operates the cooling equipment temperature. Disadvantage of scheme 1: manual switching operation is complicated, prone to errors, and has high requirements on the ...
