Title:
MOTOR
Document Type and Number:
Japanese Patent JP2002044920
Kind Code:
A
Abstract:
To solve the problem conventionally that a reluctance motor, which is sometimes difficult for use when high drive torque is required depending on a motor-applied product driven by the motor, through a driving torque generated by the motor is general to be low as the motor is rotatively driven only by reluctance torque.
The motor comprises a rotor body, having a multi-layered slit 3 arranged in the radial direction and a magnet which is embedded only in a slit 6 that is one part of the multi-layered slit, and the motor is rotatively driven by magnet torque and reluctance torque. Then, high driving torque, which cannot be obtained only by reluctance torque, can be obtained by utilizing magnet torque, in addition to reluctance torque.
