SENSOR MODULE IS CONFIGURED TO CODE THE HANDPIECE MOTOR CAP

摘要

PURPOSE: A handpiece motor with a sensor module formed in a code cap is provided to enable the accurate control of the rotation speed of a rotor by including a sensor magnet and sensing the polarity of the sensor magnet. CONSTITUTION: A housing(10) is formed in the body of a driving unit. A rotor(30) is inserted inside a bobbin(20) of a cylinder. A sensor magnet(33) comprises N-pole and S-pole formed at the rear end of the rotor. A sensor module(40) comprises a polarity sensor for sensing the polarity of the sensor module. A code cap(90) is combined with a connection cable(80).
