High-low Tcrature Coolant Test System for Motors

High-low temperature coolant test system for motors is specially used for thermal and hydro-mechanical test on permanent magnet synchronous motors, switched reluctance motors, asynchronous motors and their controllers of new energy vehicles. It can adjust the various parameters according to the testing requirements of drive motors to conduct thermal test on motors and the controllers under different temperatures.

According to the cooling type of motors, oil or water is used as coolant. 

Oil coolant type which uses oil of automatic transmission tank(Dexron-lll, Dexron-VI, Mercon V, Mercon VI, ZF) as circulation medium for testing oil-cooled drive motors directly pumps cooled oil of automatic transmission tank into the motors so that it achieves the cooling of motors. The way has a good cooling effect and high temperature control accuracy and it will not submerge motor air gap. 

Water coolant type uses demonized water or ethylene glycol solution as circulation medium for testing water-cooled drive motors according to motor testing demands. It pumps cooling medium into cooling water jackets or water pipes of motors to achieve the temperature control of motors.

Function

• Wide temperature control range: -40 ~ 120 ℃, 0.1 ℃ for minimum temperature flunctuation.

• Accurate flow control: variable frequency drive flow control, arbitrary setting of flow output, 0.2 L/min for minimum flunctuation.

• Direct cooling technology, compressor takes part in temperature control in the whole circulation, heating and cooling together.

• Avoid leakage of coolant under high temperature by using silicon carbide for circulation pump and by using graphite sealing material for pipeline.

• Multi-point temperature monitor in the circulation cycle. 

• Precise pressure gauge is used for the real-time feedback. 

• Equipped with equal-square valve to test the cooling channel inner resistance of motors. 

Applications

• High temperature destruction test, to test the demagnetization property and the lubrication reliability of motors under high temperature. 

• High temperature start-up test, to test motor's low-power performance under high temperature.

• High temperature running test, to test motor's long-time running performance under high temperature.

• Thermal performance test, to test the heat dissipation of motor' s cooling system.

• Variable temperature test, to test motor's performance under different temperatures.

• Thermal fatigue test, to test the reliability and stability of motor after long-time running. 

• Pressure drop test and flow resistance test, to test the inner resistance of motor coolant. 

• Pressure proof test, to test the sealing property of the motor cooling tunnel.
