description A brushless direct-current (BLDC) motor is provided. The motor includes a stator including a stator core and windings; a rotor shaft disposed within the stator and extending along a longitudinal axis; and a rotor including a rotor core fixedly mounted on the rotor shaft and at least one permanent magnet mounted on an outer surface of the rotor core. A sleeve is provided including a substantially cylindrical body mounted on the at least one permanent magnet and a flange that engages a first axial end of the at least one permanent magnet to constrain the at least one permanent magnet radially and along a first axial direction. Further, a fan is mounted on the rotor shaft and engaging a second axial end of the at least one permanent magnet to constrain the at least one permanent magnet along a second axial direction.
