Compared with the prior art, the water-cooled permanent magnet synchronous brushless DC motor realizes heat dissipation of the motor in a water-cooled manner and has the characteristics of good radiating effect, high efficiency, rational and practical design, simple structure, low production cost and the like, and is easy to manufacture.
Description
Technical field
The utility model relates to a kind of motor, specifically a kind of water-cooled permanent-magnet synchronous brshless DC motor.
Background technology
During the motor operation, self can produce heat, if untimely the distributing of these heats will directly influence the service life of motor.
Present motor radiating adopts air cooling way more, brush the heat generating components cooling with the fan in the motor, but fan noise is bigger, and radiating effect neither be very good.The volume of energy loss and motor is directly proportional in the motor, and the cube of its magnitude and motor lines measurement level is proportional, and the magnitude of motor radiating face is the quadratic power of motor lines measurement level.Therefore, (be subjected to materials limitations, increase capacity motor and must strengthen its size) when motor size increases, the heat that needs on the motor per unit surface to distribute will increase, and the temperature rise of motor will improve.Be that air-cooled heat radiation just can't meet the demands.
The utility model content
Technical assignment of the present utility model provide a kind of simple in structure, production cost is low, be easy to process, the water-cooled permanent-magnet synchronous brshless DC motor of good heat dissipation effect.
Technical assignment of the present utility model is realized in the following manner, comprises motor housing, and motor housing is outside equipped with the cooling water channel of the connection that is spirally coiled in the sealing on the motor housing, and cooling water channel one end has water inlet, and an end has delivery port; The cooling water channel arranged outside has radiating ribs.
Described radiating ribs is annular shape radiating ribs.
What a plurality of annular shape radiating ribs one circle circles were close to is enclosed within outside the cooling water channel.
Described motor housing outer felt is around full cooling water channel, and the cooling water channel outer ring is around full radiating ribs.
The number of described annular shape radiating ribs is 1～1000.The number of annular shape radiating ribs is as the criterion with the number of cooling water channel outer ring around full radiating ribs according to the size decision of concrete motor.
Water pump connects the water inlet and the delivery port of cooling water channel.Make the boiler water circulation in the cooling water channel flow by water pump.
Described water inlet and delivery port are separately positioned on the both ends of cooling water channel.
Described water inlet and delivery port are arranged on the same side of motor housing.
Water-cooled permanent-magnet synchronous brshless DC motor of the present utility model has the following advantages:
1, adopt water-cooling pattern to motor radiating, effective, the efficient height;
2, cooling water channel coiled coil area of dissipation is big;
3, a circle encloses a plurality of annular shape radiating ribs that is close to and is beneficial to heat radiation more;
4, make the boiler water circulation in the cooling water channel flow by water pump, accelerated band is walked the heat that motor produces;
5, water inlet and delivery port are arranged on the same side in the motor outside, make things convenient for the placement of motor;
6, reasonable in design, be easy to processing, easy to use, thereby, have good value for applications.
