Abstract :
This paper deals with design and construction of a surface-mounted Permanent Magnet Synchronous Motor to be used in elevator hoisting machine. Direct-drive solution in combination with a motor with Grain Oriented electrical steel have been proposed in order to optimize the space utilization. Manufacturing solutions adopted for the segmental core arrangement and the motor design procedure based on a combined finite elements and analytical models are discussed. A 4 kW prototype has been realized and tested. The experimental results confirm the design specifications.
