Abstract
An illustrative example embodiment of an elevator propulsion device includes at least one drive member configured to engage and climb along a vertical structure, a motor module including at least one motor configured to cause movement of the drive member and corresponding movement of an elevator cab, and a power supply including at least one energy source that is configured to provide power to the motor. The power supply is situated adjacent the motor module such that a mass of the at least one energy source provides a noise barrier to reduce transmission of noise from the motor into the elevator cab.
