Title: Pulse motor
Inventor: SHINDO SHOTARO
IPC: H02K37/06
Filed: 1986-10-17
Abstract: PURPOSE:To improve control property of output torque, by a method wherein a permanent magnet is installed within a stator or a rotor, and the output torque of the motor is made proportional to winding current. CONSTITUTION:If an excitatition coil 4 is excited, magnetic field generated by the excitation coil 4 wound on a stator 2 strengthens magnetic flux of a permanent magnet 23, and magnetic field generated by the excitation coil 4 wound on a stator 3 weakens magnetic flux of a permanent magnet 33. In this constitution, the magnetic pole of the permanent magnet 33 becomes as if it were inverted. Thereby the rotor 1 is attracted by magnetic line l5 and l6 and rotated. In this case, since the permanent magnets 23 and 33 are installed within the stators 2 and 3, the output torque of the motor becomes proportional to winding current and control property of the output torque is improved.
