The motor stator testing system adopts industrial control computers and DSP digital processing units, integrating testing of multiple items such as three-phase DC resistance, insulation resistance, power frequency withstand voltage, turn to turn withstand voltage, LCR inductance, thermistor, and rotation direction; Equipped with online communication function.
It has the advantages of fast testing speed, high accuracy, convenient use, and good reliability. It is a comprehensive testing equipment for motor stators, and all test data can be saved, queried, and printed.
The testing system is controlled by an industrial computer, which collects, records, and stores various testing data and results. Users can query, analyze, and analyze the testing data as needed. The motor stator automatic testing system can automatically complete the required inspection and testing of the motor stator online.
Motor stator testing system: composed of a DC motor, a load cell, and a tachometer generator. The stator of a DC motor is supported by an independent bearing seat, which can swing freely within a certain angle range. The casing is equipped with a force measuring arm, which works in conjunction with a load cell to detect the torque applied to the stator.
According to the principle of DC motor, the electromagnetic torque of the motor is applied to the stator and rotor. The torque experienced by the stator is equal in magnitude to the torque experienced by the rotor, but in the opposite direction, so the torque on the shaft can be measured by the stator. The mechanical torque caused by bearings, brushes, and friction during operation can cause uneven torque on the stator and rotor, which needs to be considered for measurement errors.
