Abstract
The utility model discloses an automatic test system for motor and controller used for an electric automobile. The automatic test system comprises a tested device which is composed of a tested motor and a motor controller. The tested motor is in opposite connection with a dynamometer. The power input end of the motor controller is electrically connected with a power output end of a DC power module through a first contactor. The power input end of the dynamometer is electrically connected with the power input end of an external power supply through a second contactor. The signal input ends of the first contactor, the DC power module, the second contactor and the dynamometer are respectively connected with the signal output end of a master controller electrically. The automatic test system for the motor and controller used for the electric automobile has the following advantages: realizing automatic measuring for reliability of the motor for the electric automobile and controller thereof, improving test efficiency and reducing labor cost of the test. Simultaneously, through performing real-time automatic monitoring on the temperature and flow in test, shutdown can be performed in time, thereby greatly improving test safety.
