What is the Deceleration starter?

 

M008T71471

A starter with a gear reducer installed between the armature shaft of the starter and the drive gear is called a reduction starter. The power of a series-excited DC motor is directly proportional to its torque and speed. It can be seen that when the motor speed is increased while reducing its torque, the power of the starter can be kept constant. Therefore, when a high-speed, low-torque series DC The electric motor as a starter can greatly reduce the volume and mass of the starter under the same power. However, the torque of the starter is too low to meet the requirements for starting the engine. For this reason, when a high-speed, low-torque DC motor is used in the starter, a gear reducer is installed between the armature shaft of the motor and the drive gear, which can reduce the motor speed while increasing its torque. can reduce the motor speed while increasing its torque.
