Abstract

See full text

An ultrasound probe includes an acoustical mirror that deflects an ultrasound beam generated by an ultrasound crystal toward an object under examination. The probe includes a thin flat motor whose rotor is controlled by a control system. The control system creates commutating signals that are applied to stator coils of the motor. An error signal that is related to the difference between the actual and desired positions of the object rotated by the motor is applied to the commutating signals to alter their amplitude or polarity to change the torque developed by the motor.
