The invention provides an electric rotary system, a control method of the electric rotary system and engineering machinery, and belongs to the technical field of engineering machinery. The electric rotary system comprises an electronic control unit, a controller electrically connected with the electronic control unit and used for receiving a rotation signal or a stop signal sent by the electronic control unit, a driving unit electrically connected with the controller and suitable for driving a turning device, and a brake electrically connected with the controller and used for braking a driving motor. According to the electric rotary system provided by the invention, the electronic control unit is arranged to send the rotation signal or the stop signal to the controller, the controller is used for controlling the driving unit to start and stop, and the brake is used for braking when the driving unit stops, so that the control intelligence degree of the turning device is high, starting and stopping of the turning device are facilitated, and driving and braking are both rapid.

    本发明提供一种电动回转系统、电动回转系统的控制方法及工程机械,属于工程机械技术领域,包括:电子控制单元;控制器,与电子控制单元电性连接,接收电子控制单元发送的回转信号或停止信号;驱动单元,与控制器电性连接,并适于驱动回转装置;制动器,与控制器电性连接,能够对驱动电机进行制动。本发明提供的一种电动回转系统,通过设置电子控制单元向控制器发送回转信号或停止信号,并利用控制器控制驱动单元的启停,并且利用制动器在驱动单元停止时进行制动,因此,对回转装置的控制智能化程度高,便于对回转装置的启动与停止,且驱动与制动均较为迅速。
