Description

technical field [0001] The invention belongs to the technical field of automobile product testing, and in particular relates to an automobile starter comprehensive testing device and a testing method using the device. Background technique [0002] The automobile starter is a kind of DC motor, and its performance directly affects the automobile starting performance. The performance test of the starter mainly includes the performance measurement of the main relay, the measurement of the characteristic curve, the measurement of the working characteristics and the endurance test. At present, most of the test equipment can only measure one or several of them. Since the starter is a short-term work load, its performance and its internal temperature have a great influence, so most of the test equipment currently does not consider the starter. temperature, resulting in poor measurement repeatability, especially the main relay contact resistance measurement, characteristic curve and ...

Problems solved by technology

At present, most of the test equipment can only measure one or several of them. Since the starter is a short-term work load, its performance and its internal temperature have a great influence, so most of the test equipment currently does not consider the starter. temperature, resulting in poor measurement repeatability, especially the main relay contact resistance measurement, characteristic curve and power measurement, the impact is particularly large, and most of the current equipment uses the method of multiplying the fixed force arm to measure the starter by using the force sensor. Torque, there are shortcomings such as difficult measurement of equipment, large zero drift of sensors, and low measurement accuracy. When performing endurance tests, some use ordinary motors, and some use ordinary frequency conversion motors. The starter consumes a lot of energy and the starting speed is not fast enough.
