Direct drive systems, including lift, hoist, winch and crane, yield lower cost, reduced spaces and negligible maintenance. The requirement of the lifting application is a motor with high torque and low speed, so that the direct drive motor seems to be a suitable solution. By means of a direct drive system, there is the possibility to eliminate the elevator room. The paper includes an analytical approach to the design, a comparison with the finite element analysis and a test on a final realization of this kind of motor.
