PERMANENT MAGNET TYPE MOTOR

摘要

PURPOSE: A permanent magnet type motor is provided to improve the efficiency of a motor by easily circulating coolant and oil in the motor. CONSTITUTION: A stator(120) includes a teeth unit(130) which forms a slot wound with a coil. A magnetic unit is separated from the pole(132) of the teeth unit and includes a plurality of magnet receiving units which receive a permanent magnet in the axial direction of a rotor. A rotor(200) includes the magnetic unit and a non-magnetic unit. A coolant circulation hole(250) is installed for easily circulating coolant. A rivet hole(260) is formed on the non-magnetic unit to fix a rotor core laminate.
