Abstract:
An electric vehicle drive device includes: a first motor; a second motor, and a transmission mechanism coupled to the first motor and the second motor and capable of switching a reduction ratio. The transmission mechanism includes a sun gear shaft coupled to the first motor. The first motor includes: a first stator core, a first rotor core disposed radially outward of the first stator core, and a first rotor holding member that couples the first rotor core and the sun gear shaft.

Claim (Index 14):
The electric vehicle drive device according to  claim 1 , comprising:\n a case that supports the first motor, the second motor, and the transmission mechanism; and a first rotation angle detector fixed to the case, wherein the first motor includes a first member to be detected for detecting a rotation angle of the first rotor core, the first member to be detected is configured to rotate together with the first rotor holding member and is opposed to the first rotation angle detector, and the first rotation angle detector detects magnetic flux of the first member to be detected to calculate the rotation angle of the first rotor core.
