Power system, control method thereof and excavator
The invention discloses a power system, a control method thereof and an excavator, and belongs to the technical field of engineering machinery. The power system comprises a motor control module, a motor, a diesel engine, a clutch, a coupler and a hydraulic pump. The motor control module is respectively connected with a first power supply port of the power system, a second power supply port of the power system and the motor; the motor is connected with the hydraulic pump through the coupler, and the diesel engine is connected with the motor through the clutch. Wherein the first power supply port is used for being connected with an external alternating current power supply, and the second power supply port is used for being connected with an external direct current power supply. The power source and the operation mode of the power system can be enriched, and the energy supply flexibility of the power system is improved.
本发明公开了一种动力系统及其控制方法、挖掘机，属于工程机械技术领域。动力系统包括：电机控制模块、电机、柴油机、离合器、联轴器和液压泵；所述电机控制模块分别连接所述动力系统的第一供电端口、所述动力系统的第二供电端口和所述电机；所述电机通过所述联轴器连接所述液压泵，所述柴油机通过所述离合器连接所述电机；其中，所述第一供电端口用于连接外部交流电源，所述第二供电端口用于连接外部直流电源。本发明实施例可以丰富动力系统的动力源和运行模式，提高动力系统的供能灵活性。
