[0002] At present, the motor controllers on the market are used to control one motor by one driver, or control a small number of motors by one driver. In some fields, a machine needs hundreds to thousands of motors to work together, and the same number of controllers are also required. If one driver controls one motor, when installing on site, generally, power supply wire harnesses, IO control wire harnesses, motor wire harnesses, fault output wire harnesses, etc. need to be connected. There are too many wire harnesses to plug and unplug. Each driver needs to be fixed with screws, and the number of screws for each driver is different. The installation is very cumbersome, time-consuming and laborious. Moreover, a power supply circuit and a functional circuit are required inside each driver, which will lead to a large number of circuits and high costs. Therefore, we propose a circuit structure of a brushless controller for driving multiple motors. Content of the Utility Model
