BRUSHLESS DC MOTOR FOR AN ELECTRIC CAR CAPABLE OF IMPROVING A RESPONSE PERFORMANCE OF A MOTOR

摘要

PURPOSE: A brushless DC motor for an electric car is provided to improve a response performance of a motor by minimizing an inductance value among magnetic circuit parameter of the motor.;CONSTITUTION: A brushless DC motor(1) for an electric car includes a stator, a rotor, a sensor, and a control part. The stator(10) includes an armature yoke and an armature coil. The armature coil(21) is fixed to an inner side of the armature yoke without a slot. The rotor(20) includes a permanent magnet and a rotary shaft. The permanent magnet(12) has an alternating polarity according to a circumference direction. The rotary shaft(23) is integrally rotated with the permanent magnet. The sensor detects a rotary angle of the rotor. The control part drives the rotor by controlling supply of a current into the armature coil according to a rotary angle detected by the sensor.;COPYRIGHT KIPO 2010
