Abstract
The utility model discloses a capacitor motor specialized for an axial flow fan, which comprises a housing. The housing is composed of a front end cover, a spindle and a rear end cover. A rotor is arranged inside the housing. The rotor is connected with a fan blade head through a shaft. The working point of the motor is arranged on a peak output part and close to the maximum torque. The working point of the motor is designed on the peak output part, namely, close to the maximum torque. The rotor is made as small as possible. A secondary winding and a capacitor are designed in a way to make a circular magnetic field generated when a rated power is reached. The criterion is to achieve symmetrical running. In this way, the capacitor motor ensures a high force energy index and low noise. The output characteristic curve of the motor is kept relatively smooth. When the motor matches the fan in a relatively high static pressure condition, no obvious inflection points occur in the fan output characteristic curve. The noise of the motor is lowered. The capacitor is directly arranged on the housing of the motor. Convenient maintenance is thus achieved. The motor enables high energy efficiency and is energy-saving. The motor with the axial flow fan enables operation stability in a relatively large static pressure condition.
Description
Technical field
The utility model relates to a kind of capacitor motor, and more specifically, it relates to the special-purpose capacitor motor of a kind of axial flow blower.
Background technology
The multiple pattern of prior art small-sized axial flow fan drive motors, but efficiency is all lower.The motor output characteristic curve is not mild, obvious flex point can occur with coupling blower fan output characteristic curve under higher static pressure of blower fan, and noise of motor is large.And inconvenience is safeguarded in dismounting.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and maintains easily, and energy index is high, the special-purpose capacitor motor of the axial flow blower that noise is little.
The purpose of this utility model is achieved through the following technical solutions.The special-purpose capacitor motor of this axial flow blower comprises casing, and described casing is comprised of front end housing, spindle, rear end cap, is provided with rotor in casing, and rotor connects fan blade head by axle, and the working point of motor is arranged on the peak power output place, close to breakdown torque.
As preferably: the auxiliary winding in described spindle is set in and occurs circular magnetic field when specified.
As preferably: described casing outside is provided with electric capacity.
As preferably: described front end housing, spindle, rear end cap connect from the two ends fixing and locking by holding screw.
As preferably: described bottom of shell also is provided with convenient hard-wired footing screw is installed.
The beneficial effects of the utility model are: by the working point of motor is designed at the peak power output place, namely close to breakdown torque, rotor is as far as possible little, circular magnetic field just appears in the design of auxiliary winding and electric capacity when specified, realize that symmetrical operation is as the criterion, to guarantee that energy index is high, noise is little.It is relatively mild that the motor output characteristic curve keeps, and obvious flex point do not occur with coupling blower fan output characteristic curve under higher static pressure of blower fan, reduces noise of motor.Electric capacity is directly installed on motor housing, maintains easily.The motor efficiency is high, energy-conservation.The associated axial flow blower of motor is in the situation that static pressure is larger, and operating mode is stable.
