Electric loader double-motor rotating speed control system and method
According to the double-motor rotating speed control system and method for the electric loader, a descending pilot pressure sensor transmits a descending pressure signal to a controller, and a lifting pilot pressure sensor, a tipping bucket pilot pressure sensor and a bucket retracting pilot pressure sensor transmit a lifting pressure signal, a tipping bucket pressure signal and a bucket retracting pressure signal to the controller; the brake liquid filling pressure sensor transmits brake liquid filling pressure signals to the controller, the steering gear LS port pressure sensor transmits steering LS pressure signals to the controller, the main pump pressure sensor transmits main pump pressure signals to the controller, and the controller controls the brake liquid filling pressure sensor according to the received pressure signals. And the operation state of the hydraulic motor is controlled through the hydraulic motor controller. The double-motor rotating speed control system and method for the electric loader can identify the operation intention of a driver to adjust the rotating speed of the hydraulic motor, effectively control the balance between the rotating speed of the motor and the load, reduce the energy consumption and improve the cruising ability of the electric loader.
