  • Patent number: 4890027
    Abstract: A high performance, lightweight and low cost dynamically controlled motor 10 is disclosed wherein the position control of the motor is accomplished by the use of an electronic braking apparatus 20. The dynamically controlled motor 10 of the present invention includes a standard electric motor 15 controlled by the electronic braking apparatus 20. The electric braking apparatus 20 includes a piezoelectric transducer 50 which can be activated to provide a braking force to the rotor 35. The rotor 35 is rotated to the desired stopping location, then the electronic braking apparatus 20 is activated by activating the piezoelectric transducer 50. The rotor 35 can thereby be held at the desired position.
