A drive unit for an elevator system, the drive unit including a multilayer, power circuit board; a first DC link formed in a layer of the power circuit board; a second DC link formed in a layer of the power circuit board; a first switch having a first terminal, the first switch mounted to a surface of the power circuit board; a first via electrically coupling the first terminal to the first DC link; a second switch having a second terminal, the second switch mounted to the surface of the power circuit board; and a second via electrically coupling the second terminal to the second DC link; the first via conducting heat from the first switch to the first DC link; the second via conducting heat from the second switch to the second DC link.

Low profile drive unit for elevator system

A system for managing elevator power includes a power line connected to a power grid, a motor connected to the power line and configured to receive power from the power line to drive an elevator, an alternative power source connected to the motor, and a power control system configured to control the power line to supply power to the motor to drive the elevator, to detect a predetermined threshold value of power supplied from the power line, and to supply both power from the power line and power from the alternative power source to the motor based on a determination that the predetermined threshold value of power is supplied from the power line.

Elevator power management to augment maximum power line power

An elevator car () comprises a cover () extending over at least a portion of the top surface of the car (). The cover () is mounted on a resilient support (). The car () further comprises means () for detecting displacement of the cover corresponding to the weight of a person being applied to the cover. If such displacement is detected, normal operation of the car () is prevented.
