| 20110018527 | Apparatus for detecting the travel of a lifting motor - An apparatus for detecting the travel of a lifting motor, comprising: a transmission unit positioned within a housing and having a reduction gearset and a transmission gear meshed with the reduction gearset; a threaded rod passing through a housing and threadedly coupled with the transmission gear. The transmission unit includes at least one magnet at one of the gears made of non-permeable material. The magnets are rotated clockwise or counterclockwise with the non-permeable gear when the transmission unit is driven by the motor in rotation. The number of rotation will be detected by a magnetic sensor disposed at the housing through the magnetic line of force generated by the magnet. Thereafter, the detection signals will be transmitted to a travel-calculation unit for measuring the linear displacement distance (travel) of the threaded rod in axial direction. In this way, the built-in detecting structure includes an integral arrangement and is easily secured to the treadmill. Moreover, the external interference may be reduced to enhance the precision and to prolong the service life. | 01-27-2011 |
| 20110031964 | Magnetic sensor for an elevating motor - 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. | 02-10-2011 |
