Abstract:
An electric motor includes a housing and a stator mounted to the housing. A rotor is rotatably supported relative to the stator and a drive shaft is connected to the rotor by a torque limiting clutch disposed within the housing. The electric motor with a torque limiting clutch eliminates high torque episodes due to slippery driving conditions. Also, a torque limiting clutch that features a ball-ramp device with two ramp angles performs the function of a two stage torsional vibration damper. An electric motor can have a specific torque signature that can excite certain vibration modes inside the transmission that can create noise, vibration and harshness (NVH) and durability concerns.
