Improved dynamic motor controller.

摘要

A high performance, lightweight and low cost dynamically controlled motor (10) is disclosed wherein the position control of the motor (10) 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 electronic 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.
