ABSTRACT:
A variable speed eddy current drive has a driven member and an output member. The driven member is structured and arranged to be coupled to a motor shaft. The output member is structured and arranged to be coupled to a load. The drive also has an armature and an electromagnet. The armature is coupled to either the driven member or the output member, while the electromagnet is coupled to the other of the driven member or the output member. The drive is provided with a coupler that is in addition to the armature and the electromagnet. The coupler is selectively operable between a coupled position and an uncoupled position. Actuating the coupler to the coupled position causes the output member to rotate at the same speed as the driven member, with no slip between the two members. The coupler can be actuated between the coupled and uncoupled positions while the drive is rotating. The coupler can be actuated to move either axially or radially.
