V = B * velocity * length

Velocity = 0.053 m/s

Yep. And after reaching that speed this DC motor will consume 0A and have 0N force. :) Ideal one, without any friction. Power will be consumed only to accelerate 0.454 kg to that speed.

Sly universe. :)

Without back EMF DC motors would have been prone to explosions trying to reach infinite speed. :) Including flat linear one, like in article. Motor is not just motor it is always a generator. (and vice versa) At this maximum speed ideal DC motor have zero torque/force and consume zero current, because back EMF voltage is equal to supply voltage. Real one will consume some power to fight friction.
