Abstract

The invention discloses a mover position detection device and equipment of a linear motor, and belongs to the field of mover position detection. The detection device comprises a position detection unit, a speed measurement rack and a signal processing system, wherein the position detection unit comprises at least two pairs of Hall effect sensors and a sensor mounting plate, the Hall effect sensorsare respectively fixed on a stator of a to-be-tested linear motor through sensor mounting plates, the speed measurement rack is installed on the mover of the to-be-tested linear motor, and sequentially passes through the Hall effect sensors when performing linear motion along with the mover, and the signal processing system converts a change electric signal of the Hall effect sensor into an optical signal, and determines the movement direction and the final position of the rotor through the optical signal. According to the invention, the Hall effect sensors and the speed measurement rack areintroduced to test the position of the rotor, so that the detection device has high reliability, high environmental adaptability and long service life, and safe and reliable operation of the high-speed linear motor is guaranteed.

Description

technical field [0001] The invention belongs to the field of moving element position detection, in particular to a moving element position detecting device and equipment of a linear motor. Background technique [0002] A linear motor is a transmission device that directly converts electrical energy into mechanical energy for linear motion. With the rapid development of automatic control technology, higher requirements are put forward for the positioning accuracy of various automatic control systems. The traditional rotary motor plus a set of linear motion drive devices composed of a transformation mechanism is far from meeting the needs of modern control systems. requirements. Due to the outstanding advantages of simple structure, direct transmission, and fast response, linear motors have developed rapidly, and are widely used in industrial fields such as elevators, high-speed magnetic levitation trains, and high-precision machine tools. [0003] The mover is the reciproca...
