Abstract

The invention provides a testing device for a twin trawling-loaded low-speed motor. The testing device comprises a base, wherein a torque sensor and a trawled motor as a load are arranged on the base; the trawled motor comprises a rotary encoder or a grating structure for determining the rotating speed of the motor. The trawled motor, the torque sensor and the tested motor are connected together by a coupling. A sensor for determining the change of current and voltage, a corresponding test circuit of the sensor, a slide rheostat which is connected with the trawled motor and is used for dynamically changing the load, a test circuit power supply and the like are also arranged on the base. The testing device can communicate with PC (Personal Computer) software through an RS232 communication interface. According to the testing device disclosed by the invention, accurate and stable measurement of various dynamic parameters of a low-speed motor including rotating speed and torque can be realized; and the testing device is small in size and wide in application range.

Description

technical field [0001] The invention relates to a motor testing device, in particular to a torque sensor-to-drag low-speed motor testing device. Background technique [0002] The motor test is an important part of the comprehensive evaluation of the motor assembly quality and technical performance. Due to the long operation time of traditional test devices and methods, many instruments need to be observed, and manual reading of test data and data analysis and calculation, the quality and accuracy of motor tests are affected to a certain extent. The ordinary motor test platform is only used to test the electrical parameters and main static parameters of the motor under test. It is not easy to adjust the load, and cannot be loaded with dynamic torque. It is large in size and has limited application range. [0003] The commonly used load mode in the widely used motor test technology and motor test platform is the eddy current loader or magnetic powder loader dynamometer. In t...
