DC Geared Motor stator and rotor and stator consisting of two poles (windings are analyzed.combined), or rotor windings, after electrify, has formed the rotor and magnetic field (magnetic), stator and rotor Angle between the poles in a magnetic field, the rotor and S a (N), the attraction is the motor rotate. Change the brush, can change the stator poles (assuming the Angle in the stator poles, rotor Angle for starting the poles for another side of the rotor, by the magnetic poles to the direction of the stator is motor rotation direction), thus changing the direction of motor rotation direction.
The biggest weakness of DC Geared Motor are the current problems, non-ferrous metal, high cost and the maintenance and operation. Therefore, the motor industry is trying to improve the control performance of ac motor, and instead of dc motor. However, in recent years in using thyristor rectifier instead of dc generators, has made great progress. Including dc motor rotate motor, everything is all according to the fact that we know of the two basic principles. A: is the conductor cuts flux produces induction emf, Another: the conductor in electric magnetic field in the role. Therefore, from the structure, including any motor magnetic circuit of the part and. From the above principles, any motor embodies electric and magnetic interaction, electricity and magnetism are the two contradictions in the unity of opposites. In this chapter we discussed in DC Geared Motor, the structure and working principle of DC Geared Motor is discussed "magnetic" and "electricity" interact each other, and embodies both restricts the relationship between physical phenomena and armature emf, electromagnetic torque, electromagnetic power, the armature reaction, etc.).
