Embodiment Construction

[0020] As shown in Figure 1, the inner ring motor and the outer ring motor are selected according to the speed and load of the test piece, and the corresponding inner ring inverter and outer ring inverter are selected according to the rated power and the rated power of the inner ring motor and outer ring motor Select the rated speed. The speed detection is measured by the pulse generated by the Hall sensor and the magnetic block installed on the motor shaft. First, the pulse is shaped and multiplied, and then converted into a voltage signal, which is converted into an industrial computer through AD conversion.

[0021] The transfer switch in Fig. 1 is controlled by software instructions. The torque control closed-loop works during the running-in and engagement tests, and the closed-loop control of the outer ring motor speed works during the overrunning test. The closed-loop control algorithm adopts improved PID control.

[0022] First switch the transfer switch to run-in and j...

Abstract

This invention discloses one high speed motor clutch property test method, which adopts hall sensor to get impulse signals through frequency voltage into voltage signal and finally enters work control machine through AD, wherein, the torque measurement adopts indirect computation method.

Description

technical field [0001] The invention belongs to the field of engine clutches in the field of electromechanical integration, and in particular relates to a performance test method for high-speed engine clutches. Background technique [0002] The traditional high-speed engine clutch performance test method is driven by a DC motor, and the clutch can only reach the test speed after being accelerated by the speed increaser; and the development of AC frequency conversion technology makes the AC speed regulation method better than the traditional method of increasing speed through the speed increaser , and the test cost is much lower. Currently, sensors suitable for torque detection of high-speed rotating shafts are very expensive and difficult to install. Contents of the invention [0003] The purpose of the present invention is to provide a high-speed engine clutch performance test method, the test method obtains the torque value of the clutch through indirect measurement, so...
