The utility model discloses oil -gas separation's DC Brushless motor have operate steadily, motor power density is high, long service life's advantage.
Description
Technical field
The utility model relates to drive motors, particularly relates to a kind of DC brushless motor of Oil-gas Separation.
Background technology
Monophase machine generally refers to the little power single phase asynchronous motor of powering with single phase alternating current power supply (AC220V).This motor has two phase windings usually on stator, and rotor is common mouse-cage type.The distribution of two phase windings on stator and the difference of electric power thus supplied, can produce different starting characteristics and operation characteristic.Existing single phase capacitor motor overload capacity is low, can not realize constant speed control.Single phase capacitor motor for ventilation equipment such as lampblack absorbers generally has the function of Oil-gas Separation, but after motor uses a period of time, worse and worse, greasy filth is bonded on wind wheel and makes wind wheel become heavy oil gas separation, motor can cause rotating speed to decline because of load down, serious even burns out motor.
Utility model content
The technical problems to be solved in the utility model is just: the technical problem existed for prior art, and the utility model provides a kind of and operates steadily, power of motor density is high, the DC brushless motor of the Oil-gas Separation of long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is:
A kind of DC brushless motor of Oil-gas Separation, comprise motor casing, motor shaft, and be positioned at rotor assembly and the stator module of motor casing, described rotor assembly comprises rotor core and permanent magnetism injecting ferrite magnet ring, described permanent magnetism injecting ferrite magnet ring is bonded on rotor core, more than described motor shaft, rotor core connects, described stator module comprises stator core, coil rack and coil windings, coil rack (6) is enclosed within stator core (7), coil windings (5) is formed at the upper coiling of coil rack (6), described rotor assembly is positioned at the internal round chamber of stator core, gap is provided with between described permanent magnetism injecting ferrite magnet ring and stator core.
Further improvement as technique scheme:
DC brushless motor also comprises drive and control of electric machine plate, and described drive and control of electric machine plate is located at outside motor casing.
With current detector on described drive and control of electric machine plate.
Described motor casing is 120 shells.
Compared with prior art, the utility model has the advantage of:
The DC brushless motor of the utility model Oil-gas Separation substitutes single phase capacitor motor, and motor drives and adopts constant speed control, can not reduce because of load down, motor speed and affect separating effect.With current sense function on motor drive plate, can report to the police according to load down or protection shutdown, oily trowel used for plastering rear motor for clearance can descend normal work again, and guarantee can not burn out motor because of load down.
