Abstract: A power operator for opening and closing a panel including a power module that has a motor and a gear train to transfer torque from the motor to allow for movement of the panel. The power operator includes a clutch assembly that is interconnected with the gear train. The clutch assembly includes sensors for detecting an angular speed of the clutch disks. A control module is interconnected with the clutch assembly and includes a microcontroller for adjusting an engagement force of the clutch disks using pulse width modulation such that the clutch disks are maintained in a limited slip condition.

Abstract: A power door clutch assembly including a motor that has a shaft operably connected to the motor. The clutch assembly also includes a clutch having a rotor associated with the shaft to provide rotational movement to the rotor. A stator is also provided that is positioned in juxtaposition to the rotor. A housing surrounds the clutch and includes an adjustable hall-effect sensor fixture that includes hall-effect sensors for allowing measurement of an angular speed of the clutch assembly.
