Description

Technical Field

[0001] The utility model relates to the technical field of starters, in particular to a starter stator housing mounting structure. Background Art

[0002] The starter is also called a motor. It converts the electrical energy of the battery into mechanical energy, drives the engine flywheel to rotate and starts the engine. The starter is composed of a magnetic field (stator), an armature (rotor) and a commutator. In order to increase the torque, a multi-pole magnetic field is used. There are usually 4 magnetic fields. When current passes through the armature coil, the entire coil will rotate due to a torque. When the DC motor is energized, it will generate a back electromotive force, which is proportional to the engine speed and inversely proportional to the torque, so it can meet the requirements of the starter when starting.

[0003] When the existing starter housing is installed and connected with the magnetic pole, glue is usually used to stick the magnetic pole to the inside of the starter housing to achieve the effect of fixing the magnetic pole. However, it is not easy to disassemble and separate the magnetic pole when maintaining the inside of the starter by fixing with glue, and the operation is cumbersome and complicated. In view of this, the utility model proposes a starter stator housing installation structure. Utility Model Content
