Abstract
The invention discloses a drive motor of a centrifugal fan and a motor, wherein, an end face (10) at one end of a double-layer base (7) is provided with a heat dissipation air duct hole (13); a heat dissipation air duct (14) is arranged between a base external cylinder (12) and a base internal cylinder (11); the heat dissipation air duct (14) is communicated with the heat dissipation air duct hole (13); and a shaft (1) penetrates the centre hole of the end face (10) of the base (7). The drive motor of the invention has simple and compact structure, easy manufacturing, energy conservation, improved rotating speed of the fan, increased wind pressure of the fan, improved flow rate of the fan, reduced volume of the fan, lowered manufacturing cost, increased efficiency, adaptability to the demand of technique development and the like, wherein, the rotating speed is improved from 3000r/min to 30000r/min.
Description
Technical field
The present invention relates to electric motors, especially a kind of drive motor of centrifugal fan.
Background technology
The drive motors of existing centrifugal blower is the configuration normal asynchronous, and the drive motors type of cooling all belongs to coaxial fan from heat radiation, and maximum speed can only be in 3000r/min.Its structure will have the winding stator core to be pressed into support interference fit position, and its lead wire will be drawn support; Rotor (running in bearings) winding stator core central authorities have been positioned over; Respectively with seam location and installation front end housing (flanged seam) and rear end cap, and fastening with support respectively with bolt; Again fan is installed to the rear end fan and cooperates on the position, carry key with fan and connect; Again fan housing is installed in and uses bolted on the rear end cap; Drive motors is assembled on the spiral case of centrifugal blower, and when operation device, drive motors becomes airflow pressure by the fan-shaped that is installed in the rotating shaft, and is installed in fan housing guides wind on the end cap to cooling that drive motors is dispelled the heat.Exist that rotating speed is low, blast is low, air quantity is little, volume is big, can't satisfy the needs of high rotating speed, high blast.
Improve motor speed if desire to change Electromagnetic Design on the basis of existing drive motor of centrifugal fan, not only the wind moussing loss of fan is too big, also can not bear the damage to fan of its air quantity, blast because of rotating speed is too high; If select for use the frequency conversion axial-flow fan special that motor is carried out independent heat radiation, though its motor speed can improve, vibration, the existing drive motors of volume ratio are bigger.
Summary of the invention
Purpose of the present invention provides simple in structure, the drive motors support is designed to double-deck support, fan in the rotating shaft drive spiral case of drive motors is rotated, the air duct guiding air draught that utilizes double-deck support Internal and external cycle to form, not only can form air quantity, the blast of centrifugal blower, can also carry out cooling heat dissipation to drive motors, cancel the radiator fan and the fan housing of drive motors in the existing apparatus, play the drive motor of centrifugal fan of conclusive effect for the raising of rotating speed.
Technical scheme that purpose of the present invention adopts is, including the interference of winding stator is pressed in the support, the rotor that the both sides axle is equipped with bearing respectively has been positioned over winding stator core central authorities, the support two ends are separately installed with front end housing and rear end cap with the seam location, bolt A passes front end housing installing hole and the engagement of support one end internal thread, bolt B is passed another stomidium internal thread engagement of rear end cap installing hole and support, its described end face that is double-deck support one end has the heat dissipation wind channel hole, be heat dissipation wind channel between support urceolus and the support inner core, heat dissipation wind channel communicates with the heat dissipation wind channel hole, and axle passes the centre bore of the end face of support.
The present invention, described heat dissipation wind channel has 1-8.
The present invention adopts double-deck stand structure, form required air intake and heat dissipation wind channel, the fan that the rotating shaft of drive motors drives in the spiral case is rotated, and the heat dissipation wind channel that is formed by the inside and outside tube of double-deck support guides air draught automatically, form air quantity, the blast of centrifugal blower, from the air-out of spiral case air outlet.
The present invention, have simple and compact for structure, make easily, energy savings, improve rotation speed of fan, rotating speed by 3000r/min bring up to 30000r/min, increase fan pressure, improve compressor flow, dwindle the blower fan volume, reduce manufacturing cost, raise the efficiency, characteristics such as adaptive technique development need.
