A rotor assembly for a hybrid module includes a rotor carrier, a rotor segment, an end ring, a first spacer, a second spacer, and a compressed spring. The rotor carrier includes a first outer cylindrical surface and a radial surface, and the rotor segment is installed on the first outer cylindrical surface. The end ring is fixed to the rotor carrier and arranged for fixing to an engine flexplate. The first spacer is disposed axially between the rotor segment and the radial surface, and the second spacer is disposed axially between the rotor segment and the end ring. The compressed spring is disposed axially between the end ring and the second spacer to press the first spacer, the second spacer, and the rotor segment against the radial surface for frictional torque transmission between the rotor segment and the rotor carrier.

A magnetic driving apparatus includes a base, two active magnetic units, a passive magnetic unit, and a pole-switching unit. Each of active magnetic units includes a rotational magnet. The passive magnetic unit includes two slidable magnets. One of the rotational magnets exerts magnetic push on one the slidable magnets while the remaining one of the magnets exerts magnetic attraction on the remaining one of the slidable magnets. The pole-switching unit includes a motor, a leading gear, two following gears, and a rack. The motor is connected to the base. The leading gear is operatively connected to the motor. Each of the following gears is connected to one of the rotational magnets. The rack is engaged with the gears so that the motor rotates the rotational magnets.
