A magnetic sensor for an elevating motor, and more particularly to a magnetic sensor whose magnetic induction elements are sealed within a magnetically non-permeable minor sleeve. Meanwhile, a signal transmission line is extended therefrom. In addition, the minor sleeve and the magnetic induction elements are disposed within a gear box of the elevating motor. Since the magnetic sensor in accordance with the invention is designed in a built-in type, it is not easily affected and damaged by the external environment. As a result, the service life may be prolonged. Moreover, it is modularized for a compact structure and a practical installation. In addition, it approaches more to the rotational and magnetic pole, thereby enhancing the measuring accuracy. |
