ABSTRACT:
In a brushless motor formed from a plate type stator in which a driving coil is buried, and a rotor which opposes this stator, a cutout is formed in a portion where no driving coil of a stator exists and a pulley section is provided in the periphery of the shaft-through section of the rotor. The pulley section is inserted into the rotor shaft hole formed in the center of the stator, and a pulley belt wound on the pulley section is guided outside the motor via the cutout of the above-mentioned stator. That is, the brushless motor is of an ultra-thin type in which a pulley is housed within the thickness of a motor.
