The test system of the thermal protection device of the micro-motor used in the vehicle

Abstract

The invention provides a test system for a thermal protection device of a vehicle micromotor. The test system comprises a switch device, a torque adjusting mechanism, a temperature sensing device, a current sensing device, a data acquisition device and a control device. The switch device is arranged to be in series connection with the micromotor and the thermal protection device to form a test loop. The torque adjusting mechanism acts on the micromotor. The temperature sensing device is used for measuring the temperature of the micromotor and the temperature of the thermal protection device respectively. The current sensing device is used for measuring the current of the test loop. The data acquisition device is used for collecting multipath signals synchronously. The control device is used for controlling the state of the test loop through the arrangement of the switch device, and controlling the torque of the micromotor through the arrangement of the torque adjusting mechanism. The temperature sensing device and the current sensing device are both coupled with the data acquisition device, and the data acquisition device is arranged to synchronously collect the voltage at an output end of the temperature sensing device, the voltage at an output end of the current sensing device, and the voltage at an output end of the thermal protection device.

Description

technical field [0001] The invention relates to the field of micro-motors for vehicles, in particular to a testing system for thermal protection devices for micro-motors for vehicles.
