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. Background technique [0002] In recent years, electronic information technology has brought a large-scale and far-reaching scientific and technological revolution to human society, and people's pursuit of higher and higher performance of automobiles has also promoted the rapid and diversified development of automotive micro-motor products. Micromotors are playing an increasingly important role in automotive safety, energy saving, environmental protection, and comfort. Now the automobile industry adopts a large number of new equipment, such as air conditioners, audio equipment, new electric wipers, electric window machines, ABS systems, automatic seat adjustments, automatic door locks, electric mirrors, anti-theft devices, power wireless and speed The control device and so on all need the supp...
