Abstract: A liquid-cooled motor device includes a motor casing, a motor, a coolant casing and an impeller. The motor casing receives the motor, and defines a cooling space surrounding the retaining space, a coolant intake hole, and a coolant draining hole. The coolant casing defines a drawing space, a coolant inlet and a coolant outlet. The impeller is disposed in the drawing space and connected to an output shaft of the motor, and is rotated by the output shaft to draw a coolant into the drawing space via the coolant inlet, and to force the coolant into the cooling space via the coolant outlet and the coolant intake hole, such that the coolant removes heat generated by the motor, and is expelled from the cooling space via the coolant draining hole.

Abstract: A rotor yoke is rotatable about an axis, is adapted for a plurality of permanent magnets to be mounted therein, and includes a central section, a peripheral section, and a connecting section. The peripheral section is formed with a plurality of outer slots for respectively receiving the permanent magnets. The connecting section is formed with a plurality of inner slots, and a plurality of magnetic reluctance units adjacent to outer slots and each including at least two magnetic reluctance slots that are radially aligned relative to the axis. Each of the magnetic reluctance slots permits portions of magnetic field lines generated by the permanent magnets to pass around the magnetic reluctance slots so as to increase density of the magnetic field lines.

Abstract: The present invention provides preparation of a yarn with coffee residue. The present invention also provides a novel yarn with coffee residue and applications of the same.

Abstract: A wheel hub motor includes a stator seat, a stator, an air-guiding plate, a rotor and a plurality of permanent magnets. The stator seat defines a plurality of air intake holes. The stator is mounted to the stator seat, and includes a plurality of coils. The air-guiding plate is mounted to the stator seat, and has a plurality of blades. The rotor defines a plurality of air outlet holes, and is mounted with the permanent magnets. The rotor is rotated when the coils are energized. Air flowing via the air intake holes is guided by the blades to flow into a space between the rotor and the stator, and is expelled from the space via the air outlet holes for removing heat generated by the coils.
