Abstract: A motor assembly includes a housing, a revolving shaft revolvably mounted in the housing, a magnet mounting portion surrounding and rotatable with the revolving shaft, a magnet disposed on the magnet mounting portion, a magnetically inducible core having a plurality of stator poles spaced apart from rotor magnetic poles of the magnet, and a plurality of stator windings wound on the stator poles, respectively. The stator windings are spaced apart from end walls of the housing by axial intervals. A thermally conductive bridging member is disposed to span the axial intervals to conduct heat emanating from the stator windings to the end walls so as to dissipate heat out of the housing.

Abstract: A vehicle includes a vehicle frame, a steering rod, a pair of arm units, and a drive unit. The steering rod is coupled rotatably to the vehicle frame. Each of the arm units is coupled pivotably to the vehicle frame. The drive unit is coupled to the arm units, and is operable so as to drive pivoting movement of the arm units relative to the vehicle frame.

Abstract: A boat includes a boat body and an accompanying device. The boat body includes a hull defining a first accommodation space and having left and right sides, an electric motor disposed on the hull, and a propulsion unit driven by the motor. The accompanying device includes at least one carrier assembly. The carrier assembly includes a carrier attached to either the left or right side of the hull and disposed outwardly of the hull so as to define a second accommodation space, and a battery set disposed within the second accommodation space and connected electrically to the motor for supplying electricity to the motor.

Abstract: A rehabilitation exercise device includes a head support unit having a head cushion adapted to support the head of a user, and a frame holding the head cushion and having two opposite connection ends. Two side cushions are disposed respectively on two opposite sides of the head cushion, and are connected pivotally and respectively to the connection ends so that the side cushions are rotatable toward or away from the head cushion. A biasing unit is connected to the side cushions to bias the side cushions to rotate toward the head cushion.

Abstract: A motor device includes a motor body and a set of heat-conducting pipes. The motor body includes a motor casing that defines a chamber, a stator that is disposed in the chamber, and a rotor that is rotatably disposed in the chamber. Each of the heat-conducting pipes has a heat-absorbing end that extends into the motor body, and a heat-dissipating end that is opposite to the heat-absorbing end and that extends outwardly of the motor body.

Abstract: A propeller driven surfing device includes a buoyant body having an outer contour divergent from a nose end to a front trunk segment, a rearmost surface which has a water outlet port that extends forwardly to form a water passage, and a water intake port that extends from a bottom surface to be communicated with the water passage. A drive motor is disposed in the buoyant body, and has an output shaft which extends into the passage to drive a propeller disposed in the passage. A power supply is disposed in the buoyant body and is operably coupled to the drive motor.

Abstract: A propeller driven surfing device includes an elongated body defining an accommodation chamber for receiving a drive motor and a power supply therein. A propeller is driven by the drive motor, and is disposed outwardly and rearwardly of the elongated body. A shell member includes a front surrounding segment which surrounds and which is spaced apart from the elongated body to define a passageway therebetween, and a rear surrounding segment which extends rearwardly to terminate at a distal end that is disposed rearwardly of the propeller. The front surrounding segment and the distal end respectively define a water intake port and a water outlet port which are disposed upstream and downstream of the passageway, respectively, such that water flows from the intake port and out of the outlet port through the passageway.
