P1 hybrid module
A P1 hybrid module for a vehicle includes a housing, a motor stator, an input shaft, a resolver rotor, an output flange, a motor rotor, a housing plate, and a resolver stator. The housing is arranged for fixing to an engine and a multi-speed transmission. The motor stator is fixed to the housing. The input shaft is arranged for driving connection to a flange of a damper. The resolver rotor is fixed to the input shaft. The output flange is arranged for fixing to a torque converter. The motor rotor is rotatably fixed to the output flange. The housing plate is fixed to the housing by a first fastener. The resolver stator is fixed to the housing plate radially outside of the resolver rotor.
