PURPOSE: A parallel connection type motor system is provided to reduce vibration and noises applied to an external device by offsetting a torque ripple of a first motor and a torque ripple of a second motor through the parallel connection of the first motor and the second motor. CONSTITUTION: A first motor(210) is located in a housing(100). The first motor includes a first stator(211) and a first rotor(215). A second motor(230) is connected in parallel to the first motor in the housing and includes a second stator(231) and a second rotor(235). A power transmitting unit(300) transmits a rotation force from the first motor and the second motor to the external device.
