Abstract
Official abstract text for this publication.
Disclosed is a powered transport cargo system, and a method of retrofitting a powered transport cargo system that includes braking rollers. The method includes replacing a power drive unit (PDU) of the powered transport cargo system with a PDU including a permanent magnet motor (PMM), and removing a braking roller from the powered transport cargo system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of retrofitting a powered transport cargo system comprising braking rollers, the method comprising: replacing a power drive unit (PDU) of the powered transport cargo system with a PDU including a permanent magnet motor (PMM); and removing a braking roller from the powered transport cargo system wherein the PMM has a power drive function, a static restraint braking function, and a second dynamic control braking function and comprises a magnet component including a magnet pole arc of between approximately 120 and 160 electrical degrees. 2. The method of claim 1 , further comprising replacing said braking roller with at least one of a transport roller or a cargo restraint device. 3. The method of claim 1 , wherein said PMM has a cogging torque of at least 16 ounce inch. 4. The method of claim 1 , wherein said PMM has an output torque of at least 76 ounce inches. 5. The method of claim 1 , wherein said PMM comprises a magnet component including a magnet pole arc of approximately 140 electrical degrees. 6. The method of claim 1 , wherein said PMM comprises a resistance load effectuating said dynamic control braking function. 7. The method of claim 1 , wherein said dynamic control braking function comprises regenerative braking. 8. The method of claim 1 , wherein said dynamic control braking function is triggered when the powered transport cargo system is in a powered off state. 9. The method of claim 1 , wherein said dynamic control braking function comprises at least one of a linear increasing force or a non-linear increasing force.
