The invention discloses a control method, system and equipment of a permanent magnet synchronous motor. The control method comprises the steps of receiving zero torque control information, sent by a control assembly of a new energy vehicle, of the permanent magnet synchronous motor; and in response to the zero torque control information, obtaining a first solution stored in a local memory, and sending the first solution to a power battery matched with the permanent magnet synchronous motor, so that the power battery outputs working current to the permanent magnet synchronous motor according to the first solution. And after the zero torque control is monitored to be finished, real-time torque data is monitored during the zero torque control period, and the first solution is updated according to the real-time torque data. According to the scheme, by directly obtaining the first solution stored in the local memory, the hysteresis output working current caused by the operation process is reduced, the reverse dragging torque generated by the permanent magnet synchronous motor when the new energy vehicle slides can be reduced in time, the resistance is further reduced, and the endurance mileage of the new energy vehicle is increased.
