This article establishes an enhanced sliding-mode observer (SMO) with current
measurement error compensators for the speed and position estimation in the permanent …

In order to improve the performance of the traction permanent magnet motor drives without
weight transducer for direct-drive elevator applications during starting operation, this article …

The permanent magnet traction machine has become the tendency of modern gearless
elevators, because of small volume, high efficiency, and good dynamics. However, the direct …

Direct-drive permanent magnet traction systems have become the trend of modern
elevators. Elevator traction machines tend to use low-resolution incremental encoders as …

Elevator has been the most critical equipment for vertical transportation and one of the
largest energy consumption sources in buildings. The main cause of energy waste in …

Permanent magnet synchronous motors are widely used in elevator applications. This is due
to their high efficiency and reliability, whereby motors are directly connected to the elevator …

Direct‐drive traction systems applying the permanent magnet synchronous motor have
become the trend of modern gearless elevators. To estimate and reject the non‐linear and …

In this paper, gearless elevator systems driven by Interior Permanent Magnet Synchronous
Motor (PMSM) is proposed and compared with Surface Mounted PMSM. The IPM motor with …

With the advent of permanent magnet synchronous motors (PMSM), not only efficiency of
elevator systems increased but also mechanical tensions decrease significantly. In this …
