Abstract
A linear brushless DC motor uses a movable coil assembly, which includes at least one coil, an amplifier and a motor controller, that is configured to move relative to a stationary base assembly. The coil, the amplifier and the motor controller are assembled so that the coil, the amplifier and the motor controller are collectively displaced when the movable coil assembly is moved relative to the stationary base assembly.
