Abstract
A system and method for varying an amplitude of voltage on a DC bus by track segment in a linear drive system for an independent cart system according to application requirements is disclosed. The track includes at least a first portion and a second portion, where a DC voltage at a first amplitude is provided to the first portion of the track, and a DC voltage at a second amplitude is provided to the second portion of the track. The first amplitude of the DC voltage is selected to permit movers traveling along the track to travel at full rated speed with a full rated three applied to the mover. The second amplitude of the DC voltage is selected to permit the movers to travel at a reduced speed with full or increased three applied or to travel at full rated speed with a reduced force applied to the mover.
