Definitions

  • the present invention relates to an electromotor wherein magnet-induced back electromotive force can be easily controlled, and the constant torque region or constant power region can be easily increased or decreased.
  • Servo is an automatic device which, upon detecting errors, checks operation of any mechanism by the help of an auxiliary feedback assembly and eliminates the errors.
  • Servomotors are the most widely used motor type in robotics. While these servomotors can be mechanical, they can also be used in electronic, hydraulic- pneumatic or other fields. Servomotors are assemblies wherein parameters such as output, mechanical position, speed or acceleration are controlled. The servomotor includes any AC, DC or step motor.
  • the back electromotive force applied in the coils is applied as follows: When an AC signal is applied to a coil, the alternating current enables to "produce alternating magnetic fields" around the coil.
  • the magnetic field produced around the coil has two effects on the coil.
  • the first effect of the magnetic field produced by the coils is that when the applied alternating current is increasing from zero value to the maximum value, the magnetic field of the coil resists the force that produces itself and thereby tries to decrease the increase of the current.
  • the second effect of the magnetic field produced by the coils is that when the applied alternating current is decreasing from the maximum value to zero value, the magnetic field of the coil induces voltage on itself thereby trying to decrease the passing current.
  • This voltage produced by the magnetic field, which is produced by the coil, on itself is called back-EMF.
  • the coils delay passage of the current due to back-EMF. That is to say, they cause AC currents to fall behind 90°.
  • United States patent document no. US6800977 B l discloses a multi-pole rotor including ferromagnetic pole sets extending from an inner surface of the rotor to an outer surface thereof.
  • German patent document no. DE19757502 whose inventor is the same, discloses a machine including main excitation magnets (1), which are magnetized tangentially or radially; intermediate iron pieces (2); and auxiliary magnets (3).
  • Chinese Utility model document no. CN201563041 an application in the state of the art, discloses a permanent magnetic synchronous motor with double stators and double rotors.
  • An objective of the present invention is to provide an electromotor wherein magnet-induced back-EMF can be easily controlled by means of DC coils without requiring complex control methods.

  • Another objective of the present invention is to provide an electromotor wherein permanent magnets and iron poles are located on the same shaft.
  • Another objective of the present invention is to provide an electromotor having low cost and smaller cogging torque.
  • a further objective of the present invention is to provide an electromotor which enables to control the magnetic flux in the airgap easily and inexpensively.
  • Another objective of the present invention is to provide an electromotor which enables to control the magnetic flux on each rotor independently.
