Abstract: 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.

Abstract: A cable connection hood for housing a single or multiple socket connector, has a pair of mating wall sections that have abutting flanges and contain spacer blocks in various predetermined reconfigurable patterns. A wall section has a support flange spaced from an inwardly directed lip along the front thereon, with the spacer blocks fitting between the support flange and the lip. The spacer blocks comprise center portion blocks and end blocks and have means thereon for securement within the mated wall sections. The connector hood is usable with either round or flat cables and has means for preventing dislocation of socket connectors, contained therein, from card edge connectors during vibrations or shocks.
