Abstract: The present disclosure provides a supporting and heat dissipating structure. A driver is arranged on an inner surface of a heat sink. The heat sink has protrusions for heat dissipation. An axle hole and a fixing ring are formed at the center of the heat sink. An elastic ring is arranged around the fixing ring for connecting with a supporting frame. A tubular barrel is used for connecting the heat sink to a motor. A structure for easily and firmly supporting the motor and the driver can be obtained. The structure can also absorb vibration while the motor rotating.

Abstract: The present invention provides an improved insulation structure for winding of motor stator, which is an improved design of structure for providing effective insulation for stator winding and improving winding volume. A stator piece that is arranged inside a motor body forms arrayed holes for wire winding. The holes receive insulation plates that are configured to correspond to the shape of the holes to be fit therein. Opposite ends of the stator piece receive end rings to fix and assemble thereto. End tabs formed at edges of the insulation plates are arranged to fit into and cover edge surface of a winding slot of each of the holes to realize complete coverage of the insulation for stator winding thereby ensuing operation safety when the motor is activated and put into operation.

Abstract: The present invention relates to an improved assembly of driving device for brushless motor of air-conditioner, which is a design providing a unitary and simple assembly of driving device of brushless motor, including a brushless motor body and a support rack. The support rack is made in the form of a U-shape having opposite ends forming end plates that extend high upwards. Besides providing a recess for positioning, assembling, and fixing the motor body, the U-shaped support rack forms a space that exactly accommodates the driving device therein, whereby the structure of the motor is reduced in volume and the purposes of use of simplified structure and practical convenience are realized.

Abstract: The rotor assembly contains a number of polar anisotropic ring magnets sequentially stacked, a number of supporting rings within the stacked ring magnets, and an axle threading through the supporting rings. The ring magnets are of a same diameter and length. Each supporting ring contains three co-centric rings: an inner steel ring, a middle rubber ring, and an outer steel ring. The supporting rings are positioned with substantially equal spacing and with a gap away from each aperture of the stacked ring magnets, so that additional weight elements could be positioned and adhered within the gap. The periodic positioning of a number of supporting rings could significantly reduce the weight of the motor assembly with much improved steadiness. Additionally, the middle rubber rings of the supporting rings provide a buffer mechanism for absorbing vibration and noise reduction.
