Abstract

The invention relates to a universal multi-path permanent magnet synchronous alternating current servo motor controller. The controller mainly comprises a main control board, a motor driving board, anIGBT module, a capacitor, a current sensor, a connector, a radiator, a case and the like. The controller is advantaged in that one servo motor controller can control one or at most four motors according to needs, a hardware platform is high in universality, the selection flexibility of the number of the motors is high, the design concept of integration and light weight is adopted for the whole servo motor controller, and diversified requirements of customers for servo motor control can be met.

Description

technical field [0001] The invention belongs to the field of industrial automation equipment control, in particular to a universal multi-channel permanent magnet synchronous AC servo motor controller. Background technique [0002] With the continuous development of rare earth permanent magnet materials and power electronics and control technology, permanent magnet synchronous AC servo motors have been widely used in the fields of new energy vehicles and industrial control due to their advantages of light weight, high efficiency, and small size. However, some new energy vehicles with distributed drives and some special fields of industrial control will use multiple permanent magnet synchronous AC servo motors as actuators at the same time. A single motor is controlled by a single driver, which is costly and requires installation and layout. The space is large, the line layout is complicated, the degree of integration is poor, and the economic benefit is poor. Contents of th...
