The utility model discloses a hauler for elevator, including motor and driving sheave, the driving sheave is installed on motor spindle and along with the motor spindle rotation, still is equipped with the magnetic induction encoder, and this magnetic induction encoder includes: the quilt sense part of setting on the driving sheave, and with feel the magnetic induction sensor that the part cooperateed and was in fixed position. It is located the axial terminal surface of driving sheave or the outer peripheral face of driving sheave to be felt the part. The utility model discloses set up the magnetic induction encoder on the driving sheave, the dismouting is maintained conveniently, and is just far away apart from motor internal heat generation component, and to avoid electrical moves the back that is heated for a long time and causes the influence to the magnetic induction encoder, and meanwhile, the quilt sense part radius that sets up on the driving sheave is great, and measuring result is more accurate.
