Abstract
The invention discloses a motor with heat-conducting glue arranged internally. The motor comprises a rotor unit, a case unit, a winding and a lot of the heat-conducting glue. The rotor unit comprises a mandrel and a magnet ring arranged on the mandrel in a sleeved mode. The case unit comprises a case allowing the mandrel to be installed in a rotating mode and covering the magnet ring. The winding comprises an iron core arranged on the inner circumferential surface of the case and surrounding the magnet ring, a plurality of protruding teeth extending towards to the magnet ring from the iron core, and a plurality of coils respectively winding around the protruding teeth. The heat-conducting glue is distributed on the surfaces of the coils and fills the air gap extending from the coils to the case, and therefore the heat dissipation way extending from the coils to the case is not separated, the heat energy generated by the coils can be conducted out to the case easily, and then the use effect of improving heat dissipation is achieved.
Description
The application is to be on May 27th, 2010 applying date, and application number is 201010190499.9, and what denomination of invention was " inside has the motor of heat-conducting glue " divides an application.
Technical field
The present invention relates to a kind of motor, particularly a kind of inside has the motor of heat-conducting glue.
Background technology
No. M331251, No. M322677, No. M300395, No. I250718 disclosed motor technologies of TaiWan, China letters patent book number, can accelerate cross-ventilation by the mode of a flabellum of revolution, and then improves the radiating effect of motor.
Yet while dispelling the heat, because the flow path of air-flow tends to by motor inner, so when motor used after a period of time, whole flow path has airborne dust accumulation, when dust is constantly accumulated to internal rotor, will affect motor running, and allowing air mass flow reduce, radiating effect reduces, and therefore needs at set intervals to clear up dust, otherwise the easy life-span of motor reduces, accumulated heat is damaged, and causes the puzzlement of maintaining aspect.
In addition, at present the development trend of motor is to be designed to the motor that volume is little, power is high, and if the heat energy of motor inside cannot successfully disengage, can cause internal heat energy to accumulate seriously, so that easily cause the life-span to reduce and the situation generation damaging.
Summary of the invention
The object of the present invention is to provide and a kind ofly there is radiating effect and be unlikely the motor that the inside that allows dust enter motor inside has heat-conducting glue.
The motor that inside of the present invention has heat-conducting glue is characterised in that: the motor that this inside has heat-conducting glue comprises a rotor unit, a housing unit, a winding, and many heat-conducting glues; This rotor unit comprises that one along the axle of an Axis Extension, and a magnet ring that is sheathed on this axle; This housing unit comprises that this axle of confession installs and be coated the housing of this magnet ring rotationally; This winding comprises that one is arranged at this housing inner peripheral surface and around the iron core of this magnet ring, a plurality of double wedge extending towards this magnet ring from this iron core, and a plurality of coil that is wound in respectively described double wedge; Described heat-conducting glue is distributed in described coil surface and fills up described coil and extends to the air gap between this housing.
Beneficial effect of the present invention is: see through the distribution of described heat-conducting glue, just can be so that the heat dissipation path that described coil extends between this housing have air gap to separate, so the heat energy that described coil produces is more easily derived to this housing, just can reach the use effect of heat radiation, also be unlikely and allow dust enter motor inside, in addition the radiating effect due to this motor inside obtains fully lifting, so the inside of this motor is difficult for savings heat energy, so that be quite conducive to develop into the market demands that volume is little, power is high.
