| Abstract | ||
| An elevator is a platform, either open or enclosed, used for lifting people or freight to upper floors within a building. Elevators are a standard part of any tall commercial or residential building. Mid speed elevators are commonly used in various mid-rise buildings today. In this paper, a new type of gear traction machine drive system with a permanent-magnet (PM) DC motor for mid-rise and mid-speed elevators is presented. This application of PM motor to the elevator traction machine enables several improvements including higher efficiency, greater ride comfort, and miniaturization and so on. The ideal elevator drive at larger horsepower levels should have efficient power conversion, regeneration, low harmonic distortion, and near unity power factor at the utility power lines. Therefore, voltage-fed 3-phase PWM rectifier is adopted so that DC bus voltage regulation, bi-directional power flow and controllable power factor with reduced input current harmonics are possible. | ||
