The present invention provides a mechanical-electrical connector for interconnecting two separate circuits, as in two separate stator coil sections. The conductive end pieces of the stator coil sections to be interconnected are machined such that they can be inserted into the connector. The connector provides alternating conductive and dielectric layers to connect successive stator sections in an easy-to-assemble, non-permanent mechanism. A series of external jumper conductors provide interconnection between the internal conductive layers.

A control system for a linear motor adapted to accurately supply a moving window of power to the stator coils. A plurality of individually switched stator coils run the length of a linear motor to move a rotor down the long axis of the stator. Accurate inductive-based position sensors continuously provide position data for the moving rotor. A processing unit calculates a proper time delay from a source voltage peak in order to apply power to the next stator coil in the moving direction of the rotor such that no DC offshoot/undershoot occurs. The linear motor control system optionally includes a failure prevention switching scheme in which pairs of individual stator coils on opposite sides of a double-sided stator are switched together.
