Abstract: Disclosed are a motor system and a vehicle having the same. The motor system includes: a motor (2), including: a motor housing (22), a stator core (23), a stator winding (24) and a rotor core (26), the stator core (23) being mounted in the motor housing (22), the stator winding (24) being wound around the stator core (23), the rotor core (26) being rotatably arranged relative to the stator core (23), the rotor flow path being formed at least in the rotor core (26), the rotor flow path being adapted to transport the coolant to the stator winding (24); and a valve (6) configured to control the flow of the rotor flow path.
