Abstract

The invention discloses a double-stator planar motor, which comprises a motor casing, bearings, planar stator laminations, permanent magnets, a rotor yoke, a right cover plate and a main shaft. The planar stator laminations are fixed on the inner lateral surfaces of the motor casing and the right cover plate respectively. Planar coils are arranged in the planar stator laminations. The permanent magnets are uniformly fixed on the rotor yoke. Every two adjacent permanent magnets have opposite magnetic properties. The rotor yoke is fixedly arranged on the main shaft. The motor casing and the right cover plate are arranged on the main shaft by the bearings respectively. A combination body of the permanent magnets and the rotor yoke is arranged between the motor casing and the right cover plate. The motor casing is fixedly connected with the right cover plate. Leading-out wires in the planar coils are connected with a DC power supply.
