The invention discloses an elevator traction machine. The elevator traction machine comprises an electric motor, a main body part, a rotating part, a measuring device and a rope wheel protection plate, wherein the electric motor comprises a stator fixed onto the main body part and a rotor fixed onto the rotating part; the rope wheel protection plate is fixed onto the main body part and extends to the side face of a rope wheel for driving an elevator rope; the rope wheel is accommodated between the electric motor and the rope wheel protection plate; the measuring device comprises a gear and a sensor; the gear is attached to the rotating part and rotates around the rotating axis together with the rotor; the gear is provided with a plurality of tooth parts in the circumferential direction; the distances between the adjacent tooth parts are roughly equal; the sensor installed on the rope wheel protection plate is adjacent to the tooth parts on the gear; and the sensor is used for sensing the movement of the tooth parts on the gear relative to the sensor and outputting a periodically changing measurement signal. According to the elevator traction machine provided by the invention, a special magnetic induction belt in the prior art is omitted, so that the manufacturing cost is reduced, product assembly and use are simplified, and the risk caused by magnetism reduction of the magnetic induction belt is eliminated.

    本发明公开了一种电梯曳引机,包括电动机、主体部分、旋转部分、测量装置、绳轮护板,电动机包括固定在主体部分上的定子和固定在旋转部分上的转子,绳轮护板固定在主体部分上并延伸到驱动电梯绳索的绳轮的侧面,所述绳轮容纳于电动机与绳轮护板之间;测量装置包括齿轮、感测器,其中齿轮附在旋转部分上并与转子一起绕旋转轴线旋转,齿轮在周向设置有若干齿部,相邻齿部之间的距离大致相等,安装在绳轮护板上的感测器紧邻齿轮上的齿部,并感测齿轮上的齿部相对感测器的运动并输出呈周期性变化的测量信号。本发明省却现有技术中专门的磁感应带,降低制作成本,使产品装配及使用简单化,消除因磁感应带磁性下降带来的风险。
