Characteristics
The DC series motor used in a starter motor has the following operational characteristics:
- The heavier the current drawn by the starter motor, The greater the torque generated by the motor.
- The faster the motor speed, The greater the counter-electromotive force generated by the armature coils and the less current that flows.
At the initial engine cranking stage when the motor speed is low, The armature coils generate a smaller counter-electromotive force.
