ABSTRACT:
An electronic torque switch provides substantially enhanced control in an electric motordriven torque supplying system. Utilizing an accurate and real time measurement of motor operating power, a correlation may be made with the output torque to control operation of the motor. The switch may use an operating signal based either on the absolute level of operating power or on the rate of change of operating power to control, for example, valve seating thrust levels in a motor operated valve.
