ABSTRACT:
A motor-driven power booster suitable for use in a motor-driven power steering system. The power booster comprises a casing, input and output shafts rotatably supported on the casing, a first motor for driving the output shaft, a second motor for driving the input shaft, an angle detector operatively cooperating with the first and second shafts for generating an output signal dependent on angular positions of the input and output shafts, and an electric circuit for supplying electric power to the first motor to apply an output torque to the output shaft in response to the output signal from the angle detector and for supplying electric power to the second motor to apply a reactive torque to the input shaft in response to the electric power supplied to the first motor. Since the input and output shafts are mechanically uncoupled, desired output-torque vs. reactive-torque characteristics can easily be attained by the power booster.
