The invention discloses a motor constant current test system, which comprises a processing module, wherein the processing module obtains resistance value data of a motor initial winding coil through using a motor driving voltage digital feedback signal and displays the resistance value data on a display module; and a duty ratio waveform signal is obtained according to test mode entering data of the motor and the current parameter and is transmitted to the constant current control module for adjustment; the rotation accuracy of a motor rotor can be ensured, the resistance value data of a initial winding coil of the motor is displayed on the display module, and the winding current change can be effectively observed without additionally arranging equipment; moreover, the technical requirements on testers are not high, and the cost can be effectively saved. According to the motor constant current test system and the test method, current parameter data needing to be driven by the to-be-tested motor and motor test mode entering data are input through the motor current driving parameter input end, motor control and voltage output control can be facilitated, and the purpose of controllingthe motor winding current at any time is achieved.
Description
technical field [0001] The invention relates to the technical field of motor testing, in particular to a motor constant current testing system and testing method. Background technique [0002] The constant current overload operation of small power motors is an important index for the safety performance test of small power motors. At present, most testing institutions and laboratories use manual blocking of motor rotor rotation during operation and use current testing instruments to assist in observation when performing overload tests on low-power motors, so as to change the load current of low-power motors. Its disadvantages are: manual control of load changes is random, and adjustment accuracy cannot be guaranteed; and current testing tools need to be used to observe changes in the current flowing through the windings, which increases equipment costs and requires high technical requirements for testers.
