Abstract

the invention relates to a performance testing system and a performance testing method for a portable motor, belongs to the field of performance testing of motors, and aims at solving the problem that a miniature special motor under 2Nm can not be tested by the existing measuring device. The performance testing system comprises a device bracket, a power unit, a frication unit, a measuring unit, an elastic loading unit and an electronic control unit, wherein the device bracket provides support and positioning for the power unit, the frication unit, the elastic loading unit, the pressure measuring unit, and the electronic control unit. The performance testing method comprises the following steps of: carrying out system initialization, starting the tested motor, driving an electronic drive pusher to push by a pusher motor driving circuit so as to carry out loading testing, obtaining corresponding rotation speeds and currents by testing, and drawing a current-torque curve of the tested motor according to all the obtained loading testing, thus obtaining the performance of the tested motor. The system and the method are used for testing the mechanical properties of the miniature special motor under 2Nm.

Description

technical field [0001] The invention relates to a portable motor performance testing system and a testing method, belonging to the field of motor performance testing. Background technique [0002] Most of the existing equipment for motor performance testing uses magnetic powder dynamometers. Although this equipment can complete the test of high-torque motors, it often requires high costs and low precision, and it cannot test small micro-motors below 2Nm. The motor is tested. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the current measuring device cannot test small micro-special motors below 2Nm, and to provide a portable motor performance testing system and testing method. [0004] A portable motor performance testing system, which includes a device bracket, a power unit, a friction unit, a measurement unit, an elastic loading unit and an electric control unit; [0005] The device bracket provides support and posit...
