Stator coil of DC motor and DC motor

Abstract

The invention provides a stator coil of a direct current motor and a direct current motor, and relates to the technical field of a direct current motor. The stator coil of the direct current motor includes: a copper bus bar with a plurality of turns, an insulation paper tape and a silicone rubber insulation tape. The multi-turn copper bus bar is configured as a coil profile of the stator coil of the direct current motor. The insulation paper tape is placed between two adjacent turns of the copper bus bar. The outer side of the multi-turn copper bus bar is wrapped with the silicone rubber insulation tape. The direct current motor comprises the above stator coil of the direct current motor. The stator coil of the direct current motor can effectively improve the temperature rise without changing the size and voltage of the direct current, the service life is ensured, and the output power and the torque is improved for better use.

Description

technical field [0001] The invention relates to the technical field of DC motors, in particular to a stator coil of a DC motor and a DC motor. Background technique [0002] The main heat source of a DC motor is the winding in the stator, that is, the coil. The cross-sectional area of ​​these coils is called the wire gauge. [0003] With the development of society, railway locomotives and oil field drilling rigs have more and more demands on the power and torque of the matching motors. In order to allow the motors to output greater power and torque, designers often have to enlarge the wire gauge of the stator coil and increase the Motor stator current method. [0004] However, due to the fact that the space between the locomotive and the drilling rig is generally fixed, the shape of the supporting motor cannot be enlarged, and the space for enlarging the stator coil wire gauge inside the motor is also very limited. When the stator of the motor inputs current to increase the...

Problems solved by technology

[0004] However, due to the fact that the space between the locomotive and the drilling rig is generally fixed, the shape of the supporting motor cannot be enlarged, and the space for enlarging the stator coil wire gauge inside the motor is also very limited. When the stator of the motor inputs current to increase the power and torque of the motor, it will cause rapid aging of the motor insulation. After the insulation fails, the motor will have a short-circuit fault and cannot operate, which will affect the use of equipment such as locomotives or drilling rigs.
