Abstract
Assembly of a small electric motor is facilitated by pre-assembling each coil with a support bearing and a corresponding pole piece, as well as with the cylindrical magnetic coil housing. Each support bearing includes a pair of radially-extending hooks which engage corresponding edges on the inner bore of each coil to properly align the components. The thusly pre-assembled stator sub-assembly may be inverted to receive the rotor assembly.
