Abstract
Vibrations from elevator traction machines may transmit to the nearby room and cause of the noise. For cases where it is difficult to reduce such noise with common measures, we propose employing an active mass damper (AMD) system which has a new actuator. This actuator has a simple construction which enables low production cost and generates sufficient force at frequencies higher than 100Hz. In a basic study, we installed the new AMD system to a traction machine and investigated the vibration reduction performance. We describe the construction of the new actuator and show the performance of this system.
