  • Actuator with an electric motor and a method of controlling the electric motor to maintain a current position
    Patent number: 11888429
    Abstract: For controlling an electric motor to maintain a current motor position, a motor controller determines the current motor position of the electric motor and selects (S41) from a set of stable positions, defined by cogging torque of the electric motor, a selected stable position closest to the current motor position. The controller controls the motor torque of the electric motor to maintain the motor position (S4) within a defined range around the selected stable position.

  • Outer rotor type motor having assembly mechanism in which axial, perpendicularity between a stator unit and a rotor unit is maintained
    Patent number: 11594924
    Abstract: A stator core is integrally moulded with an insulator employing an insulating resin material, together with a fixed shaft which is inserted into a centre hole in a core back portion, and the stator core and a motor circuit board are assembled as a single piece by mating a plurality of circuit board insertion pieces protruding on an axial end of the insulator on the opposite side to an output end with circuit board insertion holes.
