The utility model content
The technical problem that the utility model will solve is: for solving the problem of above-mentioned existence, provide a kind of motor to use fan-shaped magnetic pole, solved existing magnetic pole and caused the too high problem of the easy temperature of starter.
The utility model solves the technical scheme that its technical problem adopted: a kind of motor is used fan-shaped magnetic pole; The magnetic pole bodies that is formed by stacking a slice silicon steel sheet at least; Magnetic pole bodies is a sector structure, and the design of sector structure can avoid effectively that the starter temperature is too high to influence its operation.
The magnetic pole of direct current machine is divided into main pole and commutating pole, and the effect of main pole is to produce air-gap field.Main pole is made up of main pole core and excitation winding two parts, and main pole feeds the DC excitation electric current, produces the main field of machine operation, and main pole core is the part of motor magnetic circuit, and the effect of main pole winding is to feed direct current to produce excitation field.The effect of commutating pole is to improve switching-over, and issuable commutation spark between brush and the commutator generally is contained between two adjacent main poles when reducing the motor operation, is made up of compole core and commutating-pole winding.Commutating-pole winding forms with the insulated conductor coiling, is enclosed within on the compole core, and the number of commutating pole equates with main pole.
Excitation winding is wrapped on the magnetic pole and logically relative direct current and make magnetic pole produce corresponding magnetic field through rotor and the relative rotary motion completion magnetic energy kinetic energy of stator and the power conversion of electric energy.
The magnetic pole bodies lower end of the utility model is provided with the groove that matches with the beam barrel cover, and the left side of magnetic pole bodies is provided with the rectangle projection, and the right side of magnetic pole is provided with convexity, and described convexity is provided with semi-circular recesses.
In order to reduce temperature rise, magnetic pole upper end radian is less than the diameter of stator bore radian.
The beneficial effect of the utility model is, the motor of the utility model is used fan-shaped magnetic pole, adopts the non-uniform gap structure, when reducing temperature rise, can raise the efficiency greatly, can avoid effectively that the starter temperature is too high to influence its operation, and modern design is practical.
