<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive micro-brushless motor with high reliability. <P>SOLUTION: The brushless motor includes a stator and a rotor attached to the stator so as to be rotatable. The rotor includes a shaft, a rotor core fixed to the shaft and a magnet fixed to the rotor core. Two covers are respectively fixed to ends of the rotor core. One of the covers covers one end of the rotor core and at least a part of an outer peripheral surface of the rotor core in the radial direction. The other cover covers at least the other end of the rotor core. Preferably, all peripheral surface of the rotor core is substantially covered with the two covers and an interface between the two covers is sealed by an adhesive agent. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
