Title:
MOTOR FOR STARTER
Document Type and Number:
Japanese Patent JP3828656
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To inhibit the generation of spark in a motor for a starter of a vehicle in which the idling stop operation is performed by mounting the interpoles on the intermediate symmetry axis among a plurality of main field magnetic poles, winding an interpole excitation winding onto each interpole, and exciting the interpole excitation winding by the negative current.
SOLUTION: Four main field magnetic poles 30 (30a-30d) are fixed to an inner peripheral side of a york 20, and an armature 40 is mounted on an inner peripheral side of the main field magnetic poles 30. Further the interpoles 50 (50a-50d) on which the interpole excitation windings 54 (54a-54d) are respectively wound, are mounted at the inner peripheral side of the york 20 at equal intervals in such manner that the interpoles 50 are respectively located on an intermediate part between the adjacent main field magnetic poles 30. The excitation current is carried to the excitation windings 54 of the interpoles 50, so that the reactance generated by the self-induced electromotive force of the armature winding can be canceled by the rectifier electromotive force generated from the interpoles 50, the rectification phenomena can be improved, and the generation of the spark under the brush can be reduced.
