Test bed for valve electric device motor

Abstract

The invention relates to the technical field of valve electric device motor comprehensive detection such as rated torque, locked-rotor torque, current, rotation speed and noise. A test bed for a valve electric device motor comprises a motor joint, a connection flange, a torque sensor and a base, the base is provided with a first support and a second support, the motor joint is in transmission connection with a transmission shaft, the other end of the transmission shaft is in transmission connection with one end of the torque sensor, the other end of the torque sensor is in transmission connection with a magnetic powder brake, the torque sensor is installed on the first support, the connection flange is fixedly installed on the second support, and the axis of the connection flange coincides with the axis of the transmission shaft. Actual performance parameters of the motor can be detected by means of known motor experiment data, procedures of design and production of a valve electric device can be improved and optimized, quality of products is improved, and cost is lowered.

Description

technical field [0001] The invention relates to the technical field of comprehensive detection of rated torque, locked-rotor torque, current, rotational speed, noise, etc. of a valve electric device motor, and in particular relates to a valve electric device motor test bench. Background technique [0002] In the previous production and design process of valve actuators, the parameters of the motor were mostly theoretical speculation, some parameters were provided by the motor manufacturer, and there was a lack of instrument testing. Therefore, it was impossible to accurately grasp the actual performance parameters of the motor. When designing valve electric devices, due to inaccurate motor parameters, especially the starting torque, no-load torque, and stall torque of the motor, the selected motor power may be inappropriate. If the actual power of the motor is too large, it will cause waste; if the actual power of the motor is too small, the output torque of the valve electr...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to overcome the fact that in the prior art when producing valve electric devices, since most of the parameters of the motor are theoretical speculations, the accuracy of each data parameter is not high, and the actual performance parameters of the motor cannot be accurately grasped, It is not conducive to the design and production of the valve electric device. Now we provide a valve electric device motor test bench, which can accurately detect the actual performance parameters of the motor
