Permanent-magnet (PM) AC gearless machines have been an established technology in the European and Asian elevator industry for more than a decade. Within the last few years, PM installations and modernization applications have become increasingly prevalent in the North American market. A few reasons for their increased popularity include higher mechanical efficiency over a geared traction system, higher electrical efficiency compared with traction induction motors, DC with a motorgenerated (MG) set or hydraulic systems, reduced physical size that allows for a smaller machine room or machine-room-less (MRL) installations and low overall maintenance. These efficiency and installation aspects provide a new solution to building architects in their desire to provide building owners with lower operating costs, while maximizing square footage.
Gearless Permanent Magnet Synchronous Motor Traction Machine The PMSM Gearless traction machine is assembled by permanent-magnet synchronous motor, traction wheel and brake system through the encoder to achieve closed-loop control and frequency control operation.
