Abstract
A hybrid transmission including two electric motors and a plurality of planetary gear sets operatively connectable to the motors and to an engine is provided. Novel motor features are provided including structure adapted to improve reliability and to facilitate assembly. More precisely, a method is provided for locating and installing the components of a motor, including a rotor and a stator, within a covered housing to form a motor module. A plurality of rotor bearings and a position/speed sensor are also preferably added to the motor module. After the motor module is assembled, the motor may be tested and thereafter the motor module can be installed into a hybrid transmission as a single component utilizing conventional transmission assembly methods.
