Abstract
The invention discloses a motor used for a button sewing machine. The motor comprises a motor body, a rear fan housing, a front cover assembly and fans. Two parallel capacitors CR and CS are fixed at a secondary winding of the motor body. The capacitor CS is in series connection with a switch. Two axial ends of a rotor of the motor body are respectively provided with the fans in an interlaced angle. The fans, the rear fan housing, and the front cover assembly form an axial ventilation duct. Through the two fans, a through-flow ventilation duct is formed to carry out heat radiation rapidly, simultaneously the two capacitors are in parallel connection at the secondary winding, the motor is always in a rotating field state when starting and running, and torque of starting is raised. Output power and starting torque of the motor are raised, which means that starting performance of the motor is raised, simultaneously temperature rise is decreased, and a service life of the motor is prolonged.
Description
Technical field
The present invention relates to electric motors, specifically, relate to that a kind of starting torque is big, the demanding motor that is used for button-sewing machine of overload.
Background technology
General button-sewing machine is not fine with the motor starting performance, and promptly detent torque is not very big, and efficient and efficiency factor during specified operation are higher, and therefore the normal and stable operation to button-sewing machine can affect.Button-sewing machine motor in work will inevitably produce very big heat simultaneously, if untimely heat radiation can cause fault, reduces the useful life of motor.
Summary of the invention
In order to address the above problem, the invention provides that a kind of detent torque is big, the demanding motor that is used for button-sewing machine of overload, have good startability, can improve power output, also have lower temperature rise simultaneously, can increase the service life.
A kind of motor that is used for button-sewing machine comprises motor, back fan housing, preceding cap assemblies and fan, and said motor adopts two capacitor C that are in parallel
R, C
SBe fixed in the auxiliary winding of motor said capacitor C
SThe switch that is connected in series, the axial two ends of the rotor of said motor are the staggered fan of setting angle respectively, said fan and said back fan housing, the axial air duct of said protecgulum assembly composition.
Said capacitor C
R, C
SNumerical value is different.
Beneficial effect of the present invention is: forming the air channel of being used to circulate through double fan can dispel the heat rapidly, and simultaneously two electric capacity are connected in auxiliary winding in parallel, all is in the rotating magnetic field state when having guaranteed motor start-up with operation, has improved the torque that starts.
Description of drawings
Fig. 1 is a kind of overall structure sketch map that is used for the motor of button-sewing machine of the present invention;
Fig. 2 is motor interior circuit theory diagrams of the present invention.
Embodiment
As depicted in figs. 1 and 2, comprise motor 1, back fan housing 4, preceding cap assemblies 3 and fan 2 among the figure, said motor 1 adopts two capacitor C that are in parallel
R, C
SBe fixed in the auxiliary winding of motor 1 said capacitor C
SA switch is connected in series; The axial two ends of the rotor of said motor 1 are the staggered fan 2 of setting angle respectively, and said fan 2 is formed axial air duct with back fan housing 4, preceding cap assemblies 3.
Said capacitor C
R, C
SNumerical value is different.
Capacitor C of the present invention
RFixing its numerical value of auxiliary winding that inserts guarantees that when making up with auxiliary winding motor all is in circular rotating magnetic field state, capacitor C when starting and specified operation
SGuaranteed when starting speed reaches the 70-80% synchronous speed, to have higher rotational torque, improved power output, reached energy-conservation effect, its starting torque can improve 1.8 times.Fan 2 is formed the axial air channel of circulating of being used to back fan housing 4, preceding cap assemblies 3 simultaneously, can when operation, effectively dispel the heat, and reduces temperature rise, prolongs its useful life.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
