A high-precision motor closed-loop test device

Abstract

The invention relates to the field of motor closed-loop test, in particular to a high-precision motor closed-loop test device used in the motor performance debugging stage. It includes a motor, a fixed support plate, a front locking screw, a flexible coupling, a rear locking screw, a displacement sensor, a slide rail, and a pressing plate. The high-precision motor closed-loop test tooling adopts a single support plate integrated with the displacement sensor support shell, which ensures the coaxial accuracy of the assembly. A window is opened on the side of the support shell to ensure the installation space; the double nuts are tightened to prevent the displacement sensor from rolling during high-speed rotation, ensuring the rigidity of the displacement sensor and the support shell; the chute on the support shell can ensure the installation of different types of motors , to achieve the versatility of closed-loop experimental device design.

Description

A high-precision motor closed-loop test device Technical field The present invention relates to the field of motor closed-loop test, be specifically related to a kind of high-precision motor used for motor performance debugging stage Machine closed-loop test device. Background technique Motor is the important composition stand-alone of electromechanical actuator, all will carry out self's own before delivery whole assembly test Characteristic test. Among them, the closed-loop characteristic test is one of the more important ones, and its performance also directly affects the follow-up unit. machine product debugging. At present, for the closed-loop characteristic test of the motor, more double-plate symmetrical support devices are adopted to realize, as shown in Figure 1 It shows that this double-support plan has difficulty in leveling and requires high precision of the support. After deformation and stress, the process displacement sensor Easy to damage and other...
