Abstract
PURPOSE: To perform safe and sure starting, by automatically causing the starting while detecting that a sufficiently strong magnetic field is established and no load is connected when a starting switch is closed.
CONSTITUTION: When a starting switch 36 is closed, a relay contact 35a is turned on by a field winding relay energization circuit 40 to cause a field current to flow. When the field current detected by a detector 6 exceeds a prescribed level, a field condition discrimination circuit 37 supplies a signal to an armature relay energization circuit 41 to close a relay contact 34a to cause an armature current to flow. A loading discrimination circuit 38 opens the relay contact 34a when it is found out that loading is detected in terms of the armature current detected by another detector 4. The loading discrimination circuit 38 maintains the energization of an armature relay by a retention circuit 39 when a no-loading state is detected.
