Problems solved by technology

Some existing technologies for dynamic testing of permanent magnet synchronous linear motors use steel wire ropes and counterweights. The disadvantages are: one-way force, large space occupation, and unsafe factors
Others use ball screw transmission, disadvantages: slow speed, limited by stroke, linear motor is not easy to load when running at high speed
At present, there is no such test system in China

Abstract

The invention discloses a dynamic testing system for a permanent-magnetic synchronous linear motor and belongs to the technical field of motor testing. The dynamic testing system is main composed of an operating platform, a control cabinet and a motor testing platform, and the motor testing platform further comprises a U-shaped marble base, a primary linear motor, linear guide rails, sliders, a tested primary linear motor, a testing-accompanied primary linear motor, working tables, an elastic connector, a push-pull force sensor, limiting switches, anticollision devices, a grating ruler, a reading head and a drag chain. Due to a marble tabletop, influence, of vibration of the testing platform, on testing result can be reduced effectively; the sliders in a linear guide rail component are in rolling friction, friction coefficient of rolling friction is 1 / 50 that of sliding friction only, and friction force is small. Performance parameters line push force, current, speed, temperature rise and the like of the permanent-magnetic synchronous linear motor are tested by adopting two linear motors by means of opposite dragging, the dynamic testing system is simple and convenient to operate, can be used for testing motor performance when air gaps are different and can complete performance testing of linear motors different in specification.

Description

technical field [0001] The invention belongs to the technical field of motor testing, in particular to a dynamic testing system for a permanent magnet synchronous linear motor. technical background [0002] Comparative literature patent number: 200710144657.5 is a dynamic test bench for testing asynchronous induction linear motors. Due to the different types of motors, this dynamic test bench cannot be used for dynamic tests of permanent magnet synchronous linear motors. It needs to be developed according to the characteristics of permanent magnet synchronous linear motors and is suitable for permanent magnets. Synchronous linear motor dynamic test system. Some existing technologies for dynamic testing of permanent magnet synchronous linear motors use steel wire ropes to add counterweights. The disadvantages are: single-directional force, large space occupation, and unsafe factors. Others adopt the ball screw transmission mode. The disadvantages are: slow speed, limited by ...
