Series motor

Abstract

The invention relates to the technical field of motors, particularly to a series motor, which comprises a mounting shell, a heat dissipation structure, heat dissipation holes, sealing strips, first springs, supporting plates, limiting rings, a supporting structure and a motor body. According to the invention,in order to seal heat dissipation holes in a storage process,a motor can slide supportingplates, the two sides of the supporting plate are limited through limiting rings so as to guarantee the tight contact between the supporting plate and the inner side wall of a mounting shell, sealingstrips arranged on the surface of the supporting plates can be clamped with the heat dissipation holes under pushing of first springs along with the sliding of the supporting plates, and after one-to-one corresponding clamping between all the sealing strips and the heat dissipation holes is completed, sealing of the heat dissipation holes is completed, so that soil is prevented from entering the motor, and the motor is protected; and when the heat dissipation holes are opened, due to the fact that the first spring is arranged between the sealing strip and the supporting plate, the sealing strip can retract into the supporting plate in the sliding process of the supporting plate.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a series-excited motor. Background technique [0002] Single-phase series-wound motors, commonly known as series-wound motors, get their name because the armature windings and field windings work in series. Single-phase series motors are AC and DC dual-purpose motors, which can work with either AC power or DC power. Single-phase series-excited motor is a motor that has been widely used. Its advantages are due to its high speed, large starting torque, small size, light weight, not easy to stall, and a wide range of applicable voltages. The method to adjust the speed is simple and easy to implement. The motor is mainly composed of three parts: stator, rotor and bracket. The stator is composed of salient pole iron core and excitation winding. The rotor is composed of hidden pole iron core, armature winding, commutator and rotating shaft. A series loop is formed between the field w...

Problems solved by technology

[0003] For the series-excited motor used in electric vehicles, during use, the electric vehicle will generate heat during long-term continuous work, especially in hot weather for a long time will cause damage to the motor. When driving on the road, a large amount of mud will accumulate on the outside of the motor. After a period of time, the mud needs to be cleaned. If it is not cleaned for a long time, the accumulated mud may interfere with the normal operation of the motor. The traditional series-wound motor cannot be removed from the electric vehicle. Convenient, and for traditional electric vehicles, it is easy to cause mud or water to enter the interior of the electric vehicle during the cleaning process after taking it out, causing failures inside the electric vehicle and causing difficulties in later maintenance. Therefore, for the above problems A series-wound motor
