Abstract:
An securing structure of the field coil of a DC brushless motor that provides an internal mounting structure in which a stabilized bonding strength is attained while rationalizing the bonding work process. The inner rotor magnet type DC brushless motor comprises a stator section housing and a rotor section magnet having a central rotary output shaft disposed oppositely through a gap as a rotary driving system in the housing on the opposite sides of a stator side field coil having a connecting part at one end, wherein a thermal adhesive sheet is interposed between the inner circumferential surface of the housing and the outer circumferential surface of the field coil, and the field coil is bonded planarly to the inner circumferential surface of the housing.
