Systems and methods for generating currents in a plurality of CTS that may be independently controlled by a microprocessor. In some cases, a DC power source (such as a battery) is connected to each inverter. In other cases, a rechargeable DC power source (such as a capacitor) is connected to each inverter. Multiple controllable, turn-less structures may be provided in a suitable configuration with a single, main control processor or alternatively, with both a main control processor and several intermediate level command modules, each intermediate level command module coupled to a respective one of the inverters to control currents through each conductor of the respective inverter.

A magnet track for a transport device for moving an armature along the magnet track includes a plurality of linear sections each having an even number of magnets of alternating polarity disposed on a support.
