Technical analysis of the requirements for drive motors and traction sheaves of elevator gearless winches was carried out. The most of technical solutions, which are positioned as innovative and facilitated the requirements for minimum engine speed, can be considered as unsatisfactory. The workability of bi-inductor type low-speed electric drive with rotor without hanks was considered. The features of innovation drive construction and main performance indicators were described. The basic design data of bi-inductor drives for several speeds of the elevator cabin were formed. The recommendations about the choice of appropriate speed of elevator winch and diameters of traction sheave were proposed. The synthesis of control system of elevator electric drive was carried out and the electric modes of its operation were explored by use the physical model and method of mathematical modeling. The basic advantages of offered gearless elevator electric drive were outlined.
