Motor connecting device and wind generating set

The utility model provides a motor connecting device and wind generating set. Motor connecting device includes: connecting axle, connecting axle are used for coupling together the rotor of the rotor of first motor and second motor to make synchronous rotation of rotor of the rotor and the second motor of first motor, the supporting member, the outside at the connecting axle is established to the supporting member cover for couple together the stator of first motor and the stator of second motor. According to the utility model discloses a motor connecting device links together through the rotorof same root connecting axle with the motor to link together through the stator of supporting member with the motor, realize the stack of the power (moment of torsion) of series connection and the motor of motor, thus the output of increase motor. In addition, according to the utility model discloses a motor connecting device owing to connect similar coaxially designed through same root connecting axle between the motor,
