In the field of direct current machine, the main magnet exciting coil that adopts is arranged on rotor, by commutator supply magnet exciting coil electric current, is subject to electromagnetic force to realize coil current－carrying conductor and rotates in magnetic field.Owing to adopting commutator to power, the current of commutation in commutation process makes direct current machine there is the problems such as energy consumption is large, electric arc is large.
Summary of the invention
The deficiency that the object of the invention is to exist for prior art provides a kind of direct current ring motor, this current of electric is little, multiturn number, output electromagnetic torque are large, excitation wire ring is fixed on casing, and magnetic pole is arranged on rotor, connects power supply continuously with conducting ring with carbon brush.Do not adopt commutator to power, power of motor is made full use of and plays, and play energy-saving and cost-reducing effect.
For achieving the above object, present invention employs following technical scheme.
A kind of direct current ring motor comprises casing, excitation wire ring, bolt, front end housing, bearing, armature spindle, left magnetic pole, middle magnetic pole, right magnetic pole, carbon brush, conducting ring, rear end cap.Described excitation wire ring is fixed by bolts to the middle part of casing, left magnetic pole, middle magnetic pole and right magnetic pole is provided with at the periphery of excitation wire ring, described front end housing and rear end cap are fixed on the two ends of casing, described carbon brush is fixed on the rear of casing, described front end housing and the central authorities of rear end cap are provided with bearing, described bearings armature spindle, and armature spindle is fixed with conducting ring, and conducting ring connects with carbon brush.
Described excitation wire ring is provided with magnet steel, coil groove and bolt hole.
Described left magnetic pole, middle magnetic pole and right magnetic pole are provided with magnet exciting coil, magnet steel and structural steel.
Described left magnetic pole, middle magnetic pole, right magnetic pole, magnet exciting coil, magnet steel also can replace with permanent magnet, and adopting permanent magnet to do magnetic pole can remove carbon brush.
Direct current ring motor of the present invention also can be fixed on casing left magnetic pole, middle magnetic pole and right magnetic pole, excitation wire ring is fixed on rotor, is powered continuously by carbon brush and conducting ring.
Operation principle of the present invention: magnet exciting coil around group from the left side around to the right side, the sense of current on such left side just from the top down, the sense of current on the right side then from bottom to top, the electric current in the direction from the top down on the left side cut the N pole field of magnetic pole in left side, according to motor left hand rule, the direction of electromagnetic force is from paper direction out; And on the right side of magnet exciting coil winding, the electric current in direction cut the N pole field of right magnetic pole from bottom to top, according to left hand motor rule, the direction of electromagnetic force is from paper direction out; Such magnet exciting coil is equidirectional around the group left side and the electromagnetic force on the right side, the torque that motor produces under electromagnetic force and operating; Because magnet exciting coil is fixing around group, electromagnetic force makes magnetic pole rotate.
The present invention compared with prior art, has following effect:
(1) small area analysis, multiturn number, be conducive to magnet exciting coil and increase work efficiency; (2) conducting ring is powered continuously, excitation wire ring is fixed on casing, saves commutator, and design avoids the loss and inconvenience that the commutator current of commutation causes like this; (3) left magnetic pole, middle magnetic pole, right magnetic pole can select permanent magnet to do magnetic pole, do like this and can save carbon brush and conducting ring, more economize on electricity and increase work efficiency.
