Aiming at the demand for on-line test of factory motors based the new mode of intelligent motor manufacturing, the on-line test technology of motors has been studied, and fully automatic, intelligent and information-based on-line motor test equipment has been developed. The equipment can complete the automatic unmanned detection of DC resistance, insulation, voltage resistance, locked-rotor, no-load, noise, and temperature of three-phase asynchronous motors in the power range of 0.75～15 kW and voltage range of 220～690 V, with a test cycle of 60 seconds per unit. The development and application of the equipment have improved the consistency, accuracy and traceability of the motor on-line test data, and the quality of the motor under high-intensity and fast operation is guaranteed. It provides equipment support and technical support for the promotion and application of the new mode of motor intelligent manufacturing.
