Torrance, Calif.-— Alpha Step is a two-phase, hybrid, geared step motor and driver package said to eliminate missed steps. It uses a built-in feedback device that constantly monitors the motor shaft to detect and correct for loss of synchronism. Having a built-in feedback device minimizes the size requirements for the motor and helps protect the device from shock loads and temperature extremes. Alpha Step has high response since it runs open loop under normal conditions and only runs in closed loop when a position of deviation of 1.8 ( or greater is seen. Alpha Step is reportedly well suited for systems requiring high compliance, such as belts and pulleys. Oriental Motor USA
