摘要： An electromagnetic brake system and brake for controlling motion between a first machine body (32) and a second machine body (34) is provided. The electromagnetic brake system and brake include an interior core member (36), the interior core member coupling with the first body (32). The electromagnetic brake includes an outer exterior member (38), the outer exterior member enclosing the interior core member, the outer exterior member coupling with the second body. The electromagnetic brake includes a resilient spring brake lock member (40) having a brake torque stiffness, the resilient spring brake lock member (40) between the interior core member (36) and the outer exterior member (38), the resilient spring brake lock member (40) engaging the interior core member (36) wherein the resilient spring brake lock member inhibits rotation between the outer exterior member and the interior core member, and an electromagnetic field applied by an electromagnetic unlocking member disengages the resilient spring brake lock member from engaging the interior core member and provides for rotation between the outer exterior member and the interior core member.
