Problems solved by technology

However, the controller of the brushless motor in the prior art can only drive a single brushless motor to work, and there is no redundant backup function
In addition, the wiring methods of the controllers are different, which makes the structural installation methods incompatible, and it is not easy to integrate when forming a large-scale motion control system

Abstract

The invention discloses a multichannel brushless motor controller which comprises a box, a first relay, second relays, a main board, first connectors, second connectors, control modules and at least two drive modules. The main board is used for monitoring the operation states of the control modules and the at least two drive modules and controlling the switch of the first relay. The first relay is used for the switch between the two control modules and between the at least two drive modules. The control modules are used for receiving commands of an upper computer, recognizing the commands of the upper computer, sending drive orders to the at least two drive modules and sending pulse signals to the main board. The drive modules are used for receiving the drive orders of the control modules so as to drive brushless motors to work. The multichannel brushless motor controller can simultaneously control the multiple brushless motors to rotate and has the redundant backup function, and the reliability of the controller is improved.

Description

technical field [0001] The invention relates to the field of mechatronics, in particular to a multi-channel brushless motor controller. Background technique [0002] A brushless motor is a typical mechatronic product, which is a self-synchronous motor system or a self-controlled variable frequency synchronous motor composed of a motor body, a position detector, an inverter and a controller. With the rapid development of power electronics technology and high-performance permanent magnet materials, its application has rapidly developed from the initial military industry to aerospace, information, home appliances, medical and other fields. The brushless motor does not need a commutator, and the alternating current given by the controller of the brushless motor drives the armature to rotate, so its service life and reliability far exceed that of the brushed motor, and it has strong competitiveness. [0003] The performance of a brushless motor depends largely on the performance...
