Abstract
The utility model relates to a motor ventilation cooling structure realizing effective cooling. The structure comprises a fan housing, the fan housing is internally provided with a motor shaft, a stator and a rotor, one end of the motor shaft is equipped with a fan, and the other end of the motor shaft stretches out of the fan housing; and the structure is characterized in that the fan is located at a front end of the fan housing, an empty chamber is formed among the stator, the rotor and a rear end of the fan housing, and the fan housing is provided with a plurality of vents in positions of the empty cavity. The motor ventilation cooling structure realizing effective cooling is novel and simple in structure, low in cost, convenient to manufacture, and firm in mounting, can effectively reduce the temperature rise of the motor, and prolong the service life of the motor.
Description
Technical field
The utility model relates to a kind of electric machine structure, and especially a kind of effectively motor ventilation cooling structure of cooling of realizing belongs to the electric machine structure technical field.
Background technology
Motor is in service in work, electric current produces heat in stator winding and rotor winding, the bearing friction of rotor also produces heat, on the other hand, because the variation in magnetic field produces loss in unshakable in one's determination, temperature unshakable in one's determination is raise, these heats of general motor conduct to casing, and all the air quantity that is produced by the fan rotation blows away heat.And from fan motor front end far away, heat radiation is difficult relatively.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of effectively motor ventilation cooling structure of cooling of realizing is provided, and motor is effectively cooled off, and reduces the motor casing temperature rise.
According to the technical scheme that the utility model provides, a kind of effectively motor ventilation cooling structure of cooling of realizing comprises the fan housing housing, and motor shaft, stator and rotor are set in the fan housing housing, and an end of motor shaft is installed fan, and the other end of motor shaft stretches out the fan housing housing; Feature is: described fan is positioned at the front end of fan housing housing, forms cavity between the rear end of stator, rotor and fan housing housing, on the fan housing housing at this cavity place several ventilating openings is set.
Novel structure of the present utility model, simple, cost is low, and is easily manufactured, installs firmly, can effectively reduce the temperature rise of motor, improves the useful life of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in Figure 1: the described realization effectively motor ventilation cooling structure of cooling comprises fan housing housing 1, motor shaft 2, fan 3, ventilating opening 4 etc.
As shown in Figure 1, the utility model comprises fan housing housing 1, and motor shaft 2, stator and rotor are set in the fan housing housing 1, and an end of motor shaft 2 is installed fan 3, and the other end of motor shaft 2 stretches out fan housing housing 1; Described fan 3 is positioned at the front end of fan housing housing 1, forms cavity between the rear end of stator, rotor and fan housing housing 1, and several ventilating openings 4 are set on the fan housing housing 1 at this cavity place.
Motor ventilation cooling structure described in the utility model is with fan housing housing 1 lengthening, between the front end of fan housing housing 1 and stator, rotor, form cavity, thereby fan 3 by the ventilating opening on the fan housing housing 14 motor surface heat is taken out of cooling air the lead front end of fan housing housing 1.
Novel structure of the present utility model, simple, cost is low, and is easily manufactured, installs firmly, can effectively reduce the temperature rise of motor, improves the useful life of motor.
