Electric motor with bobbin columns to prevent bulging coils

An electric motor comprising:

• an outer ring yoke portion forming an outer ring;
• a stator core in which an inner ring magnetic pole portion is fitted in said outer ring yoke portion, said inner ring magnetic pole portion including slots and a plurality of magnetic pole pieces;
• an insulating portion covering said inner ring pole portion of said stator core;
• a funnel-shaped insulating resin formed integrally with said insulating portion and covering one end face of said inner ring magnetic pole portion, said insulating resin including a first through hole for a rotational shaft having continuity with a center of said inner ring magnetic pole portion;
• bobbin columns having pins protuberantly formed on said plurality of magnetic pole pieces, said bobbin columns being formed integrally with said funnel-shaped insulating resin;
• a stator in which a funnel-shaped insulating cover including a second through-hole for said rotational shaft is disposed on another end face of said inner ring magnetic pole position, wherein coils are wound between a plurality of slots and terminals of said coils are twined around a plurality of pins, said second through hole communicating with said first through hole when said rotor is located in said inner ring magnetic pole portion;
• a terminal holder having an opening at a center thereof, said terminal holder provided with electronic devices connected to said plurality of pins of said bobbin columns;
• guide grooves for guiding leads to pin holes formed at positions quartering said terminal holder;
• and
• deformable protruding portions provided for sandwiching said guide grooves.

An electric motor comprising:

• a rotor, including a rotational shaft at a center of said rotor;
• a plurality of magnetic pole pieces radially arranged to accommodate said rotor;
• a plurality of slots, formed between said plurality of magnetic pole pieces, to accommodate a plurality of coils;
• an outer ring yoke portion, including a plurality of recess portions, for fixing a position of said plurality of magnetic pole pieces;
• an insulating cover for covering an outer side of said rotor and including a cylindrical through-hole through which said rotational shaft is inserted;
• and
• bobbin columns, located on an outer side of said insulating cover, for positioning said plurality of coils extended from said plurality of slots.
