2. Description of the Related Art A prime mover such as a gas turbine engine must be externally driven until a predetermined number of revolutions is reached at startup, and is often started by a starter motor. This starter motor requires a large starting torque and a small size, and a DC series motor is usually used.
In this DC series motor, the armature current flows through the field as it is, and when stopped, the internal impedance is extremely small and a large current flows, but the current is limited by the back electromotive force generated as the rotation increases. become. For this reason, when starting from a stopped state, a method in which the inrush current is suppressed low by starting the starter motor by lowering the supply voltage from the battery and a rated voltage is applied to the starter motor when the number of rotations increases to some extent Is used.
