Abstract

The invention relates to a device for measuring the positioning force of a magnetoelectric linear motor, belonging to the field of motor test and aiming to solve the problems of low measuring precision, a plurality of personal measurement factors and uncontrollable measurement process of a spring balance which is adopted to measure the positioning force of the magnetoelectric linear motor. The device for measuring the positioning force of the magnetoelectric linear motor adopts two synchronizing wheels, a synchronizing belt, a magnetoelectric linear motor mover and a step motor to form a mechanical-structure closed loop; a miniature step rotation angle of the step motor is converted to the miniature displacement of the magnetoelectric linear motor mover in the horizontal direction; a computer, two tension sensors, the step motor and step motor control form an electric control system closed loop, the computer is utilized to process signals of the two tension sensors to obtain the positioning force of the magnetoelectric linear motor, realize the high-precision equidistant position control and record the displacement and the positioning force of each step to form a whole-course positioning force curve. The invention is mainly used for measuring the positioning force of the magnetoelectric linear motor.

Description

technical field [0001] The invention relates to a positioning force measuring device of a permanent magnet linear motor, which belongs to the field of motor testing. Background technique [0002] Linear motor is an extension of traditional motor, which has been valued and recognized by all walks of life. The measurement of the positioning force of the permanent magnet linear motor has always been an indispensable step in the study of the permanent magnet linear motor. The accurate measurement of the positioning force of the permanent magnet linear motor is of great significance to the design and optimization of the permanent magnet linear motor. The existing permanent magnet linear motor positioning force measurement such as figure 1 and figure 2 As shown, the device consists of a test platform 1, a mover 2 of a permanent magnet linear motor, a stator 3 of a permanent magnet linear motor and a spring balance 12. By manually pulling the spring balance 12 to drive the move...
