through the reduction gear, the isolator, and the crank
3. Basic parameters
Stator has four magnetic steels with four poles in total, and four carbon brushes;
Specification: 12V650W;
Rotation direction of output shaft: viewed from the tooth end, clockwise; Output features
4. Failure mode
Motor open circuit failure; Excessive wear of carbon brushes;
Broken stator magnetic steel;
Faded magnetic properties of the magnetic steel;
Frictional short circuit between the enameled wire of the rotor winding and the stator; If
the bearing is failure,the motor runs with a strange noise.
Poor oil seal,short circuit failure of oil inlet in Motor; Poor waterproof, and the water inlet
performance of Motor decreases.
Motor characteristics
Start relay
1. Outline drawing
2. Working principle
Turn on the voltage at both ends of the relay coil so that it can generate electromagnetic
force and pull on the movable contact and the fixed contact. The small current through
the operating switch and relay coil can control the large current through the starting motor
and relay contact. The starter relay also contains the power circuit (power pole B, coil
