Patent abstract
The brushless motor includes a coil array, a magnet array, a magnetic sensor, a drive control circuit for driving the coil array, and a temperature sensor for detecting a detection target temperature associated with either the coil temperature or the driving element temperature. The drive control circuit reduces the effective value of driving voltage supplied to the coil array when coil temperature detected by the temperature sensor has exceeded a prescribed threshold value.
