Description

A kind of large torque brushless motor
Technical field
The utility model is related to a kind of large torque brushless motors.
Background technology
Brshless DC motor is made of motor body and driver, is a kind of typical electromechanical integrated product.Due to Brushless direct current motor is run with autocontrol, so will not turn as the synchronous motor of heavy load starting under frequency control Another plus startup winding, will not generate oscillation and step-out in load sudden change on son.
Existing brushless motor heat dissipation effect is poor, and brushless motor cannot overcome the influence of temperature height variation, cause height The loss and waste resource of electric energy.
Utility model content
In view of this, the utility model aim is to provide, a kind of good heat dissipation effect, the small large torque of the temperature difference is brushless in casing Motor.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is:
A kind of large torque brushless motor, includes casing, and bearing hole, the bearing hole are provided at the center of the casing It is inside provided with bearing, running through at the center of the bearing has shaft, and stator coil is provided on the outer wall of the bearing hole, described The peripheral side of stator coil is provided with rotor, and longitudinal section of the rotor is arranged in " mountain " font, the lower end of the shaft with It is fixedly connected at the center of the rotor, permanent magnet is provided on the madial wall of the rotor, is arranged on the lower wall of the casing There are exhaust vent, the top of the casing to be provided with fan hub, air inlet hole is provided on the fan hub, is arranged in the fan hub There is radiator fan.
It is provided with strainer preferably, being provided on the inner wall of the casing of the exhaust vent;The top of the fan hub It is provided with strainer.
Preferably, the shaft is interference fitted with the bearing.
Preferably, the radiator fan clamping is fixed in the shaft.
Preferably, the top of the casing is fixed with shell cover, the fan hub is removably connected in the shell cover.
The utility model has the technical effect that following aspect:Due to being provided with fan hub, wind on the top of casing It is provided with air inlet hole in fan case, radiator fan is provided in fan hub, the blowing of radiator fan face stator coil being capable of effective band Walk the heat of stator coil generation;Since the lower part of casing is provided with exhaust vent, one circulation of exhaust vent and air inlet formation Air duct keeps the air quantity for flowing through stator coil big, improves heat dissipation effect, reduces the temperature difference of casing internal;Due to air inlet hole and going out Air holes is both provided with strainer, and dust is avoided to enter casing internal, influences the operation of motor;Since fan hub is removably connected to institute It states in shell cover, repair cleaning fan is convenient;Since fan clamping is fixed in the shaft, shaft rotation drives fan rotation, Without separately connecing power supply, structure is simplified.
Description of the drawings
Fig. 1 is the sectional drawing of the large torque brushless motor of the utility model.
Specific implementation mode
Below in conjunction with attached drawing 1, specific embodiment of the present utility model is described in further detail, so that the utility model skill Art scheme is more readily understood and grasps.
In the present embodiment, it is to be understood that term " centre ", "upper", "lower", " top ", " right side ", " left end ", " top ", " back side ", " middle part ", etc. instructions orientation or positional relationship be based on the orientation or positional relationship shown in the drawings, only It is of the invention for ease of description, does not indicate or imply the indicated device or element must have a particular orientation, with spy Fixed azimuth configuration and operation, therefore be not considered as limiting the invention.
In addition, the connection between component or fixed form if not otherwise specified in this embodiment, connection or solid Determine mode can be fixed by bolt commonly used in the prior art or pin fix or axis pin connection etc. modes, therefore, this It is no longer described in detail in embodiment.
With reference to figure 1, a kind of large torque brushless motor includes casing 1, bearing hole is provided at the center of the casing 1 11, bearing 4 is provided in the bearing hole 11, through having shaft 3, the shaft 3 and the bearing at the center of the bearing 4 4 interference fits.
Stator coil 5 is provided on the outer wall of the bearing hole 11, the peripheral side of the stator coil 5 is provided with rotor 7, Longitudinal section of the rotor 7 is arranged in " mountain " font, is fixedly connected at the lower end of the shaft 3 and the center of the rotor 7, Permanent magnet 6 is provided on the madial wall of the rotor 7, heavy coil is used as rotation as stator, the permanent magnet 6 of light weight, Keep the power that rotor consumes few, the torque of output is also with regard to opposite bigger.
It is provided with exhaust vent 13 on the lower wall of the casing 1, is provided on the inner wall of the casing 1 of the exhaust vent 13 and is arranged There are strainer, the top of the casing 1 to be provided with fan hub 8, the fan hub 8 is connected with the casing 1, the casing 1 Top is fixed with shell cover 2, and the fan hub 8 is removably connected in the shell cover 2, and air inlet hole is provided on the fan hub 8 81, radiator fan 9 is provided in the fan hub 8, and 9 clamping of the radiator fan is fixed in the shaft 3, the fan hub 8 top is also equipped with strainer, prevents dust from entering the inside of casing 1, and the component inside effective protection casing 1 makes its use Longer life expectancy.
The utility model has the technical effect that following aspect:Due to being provided with fan hub, wind on the top of casing It is provided with air inlet hole in fan case, radiator fan is provided in fan hub, the blowing of radiator fan face stator coil being capable of effective band Walk the heat of stator coil generation;Since the lower part of casing is provided with exhaust vent, one circulation of exhaust vent and air inlet formation Air duct keeps the air quantity for flowing through stator coil big, improves heat dissipation effect, reduces the temperature difference of casing internal;Due to air inlet hole and going out Air holes is both provided with strainer, and dust is avoided to enter casing internal, influences the operation of motor;Since fan hub is removably connected to institute It states in shell cover, repair cleaning fan is convenient;Since fan clamping is fixed in the shaft, shaft rotation drives fan rotation, Without separately connecing power supply, structure is simplified.
