Rudder shifting device driven by double-stator permanent magnet motor

The utility model relates to a steering device driven by a double-stator permanent magnet motor, which is characterized in that the coaxial double-stator permanent magnet motor provides power for the steering device, and double stators adopt a series structure and share one motor rotating shaft; a single-stator working mode or a double-stator working mode of the permanent magnet motor is realized through the double-stator permanent magnet motor controller and the two drivers; a spline shaft at the output end of the double-stator permanent magnet motor is inserted into an input spline shaft sleeve of the planetary gear speed reducer, and the steering torque on the spline shaft is amplified through the speed reducer and is transmitted to the pinion through the speed reducer; and a fan-shaped gear ring meshed with the pinion is fixed on the tiller through a transmission pin to drive the tiller to rotate, so that a rudder blade on the tiller is driven to rotate. By means of the double-stator integrated design, re
