Modular laser level determination system for construction, has rotation drive module including brushless motor with stator fixed to part that is tilted for determination and adjustment of inclination based on reference place

摘要

The system has a beam generator in a housing fixed to a positioning unit. A rotation drive module is arranged along a direction coaxial with a central line of the beam. The module includes a brushless motor with a hollow shaft (51) and a stator (53) fixed to a part that is tilted for determination and adjustment of the inclination based on a reference place.
