Abstract
Abstract A small electric motor has a housing which is secured to a cover. The cover has a longitudinally-extending guide member formed on one side thereof which partially surrounds the stator. A longitudinal groove which is formed in the guide member engages with a projection formed on the outside of the stator. An external connection terminal is secured to the cover and is electrically connected to the stator coil by a stator coil terminal which passes through an access hole formed in the guide member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
188 words
A small electric motor comprising: a rotor; a stator which surrounds said rotor and which has an engaging member formed thereon, said stator having a stator coil and a stator coil terminal which is connected to the ends of said stator coil and extends to the outside of said stator; a housing which surrounds said stator and journals one end of said rotor; a cover which is secured to said housing and journals the other end of said rotor, said cover having a longitudinally-extending guide member formed thereon which partially surrounds said stator, said guide member having an engaging member formed thereon which engages with the engaging member of said stator, said guide member having an access hole formed therein, said stator coil terminal being aligned with said access hole when said engaging member of said stator is engaged with said engaging member of said guide member; and an external connection terminal which is secured to said cover in the vicinity of said access hole, which extends through said cover between the inside and outside of said motor, and which is electrically connected to said stator coil terminal.
Claim 2
Dependent Claim
188 words
A small electric motor comprising: a rotor; a stator which surrounds said rotor and which has an engaging member formed thereon, said stator having a stator coil and a stator coil terminal which is connected to the ends of said stator coil and extends to the outside of said stator; a housing which surrounds said stator and journals one end of said rotor; a cover which is secured to said housing and journals the other end of said rotor, said cover having a longitudinally-extending guide member formed thereon which partially surrounds said stator, said guide member having an engaging member formed thereon which engages with the engaging member of said stator, said guide member having an access hole formed therein, said stator coil terminal being aligned with said access hole when said engaging member of said stator is engaged with said engaging member of said guide member; and an external connection terminal which is secured to said cover in the vicinity of said access hole, which extends through said cover between the inside and outside of said motor, and which is electrically connected to said stator coil terminal.
Claim 3
Dependent Claim
58 words
A small electric motor as claimed in claim 1, wherein said engaging member of said stator is an outwards projection which is formed on the outside of said stator, and said engaging member of said guide member is a longitudinally-extending groove which is formed on the inner surface of said guide member and which engages with said projection.
Claim 4
Dependent Claim
21 words
A small electric motor as claimed in claim 1, wherein said guide member is a cylinder which substantially surrounds said stator.
Claim 5
Dependent Claim
39 words
A small electric motor as claimed in claim 1, wherein said guide member comprises a plurality of projections which extend longitudinally from said cover and which are spaced apart from one another in the circumferential direction of said stator.
