Summary:A main winch device driven by a permanent magnet synchronous motor comprises a main winch frame (6) and a main winch (5) installed on the main winch frame (6), and is characterized in that the permanent magnet synchronous driving motor (1) is installed at the input end of the main winch frame (6) through a transition disc (2), and an output shaft of the permanent magnet synchronous driving motor is connected with the input end of a main winch speed reducer (4) through a spline shaft (3); and a brake for controlling the start and stop of the main winch (5) is arranged in the main winch speed reducer (4). Due to the fact that the power source of the winch is driven by the motor, the transmission efficiency reaches up to more than 98%, instant doubled torque can be provided, construction noise is low, the cost of the power source of the winch is reduced, and the winch closely follows the national carbon neutralization target step. According to market verification of batch pure electric rotary drilling rigs, the
