Apparatus for transferring torque magnetically
An apparatus for transferring torque magnetically with a primary rotary member and a secondary rotary member. The primary rotary member has permanent magnets, the secondary rotary member with electro-conductive materials. The secondary rotary member also having magnetically permeable material. The secondary rotary member is placed partially or totally inside the primary rotating member. This causes the two rotary members to axially overlap one another more or less as desired. Rotation of the primary rotary member causes rotation of the secondary rotary member, since magnetic flux lines emanating from the permanent magnets mounted on the primary rotating member, cut through all, or part of, the electro-conductive material placed on the secondary rotary member. This can vary the torque transmitted between the two rotary members, thereby enabling the varying of the rotational speed of the secondary rotary member relative to the primary rotary member.
1. An apparatus for transferring torque magnetically comprising:
a primary torque driving rotary member and a secondary driven rotary member;
the primary rotary member axially overlapping said secondary rotary member;
the secondary rotary member being surrounded by said primary member;
the primary rotary member having permanent magnets mounted on it;
the secondary rotary member having electro-conductive elements and magnetically permeable materials neither of which are ferromagnetic, and not having permanent magnets;
said secondary rotary member axially overlapped by said primary rotating member wherein a means for varying said primary rotary member's axial position relative to said secondary rotating member is provided; and
said primary rotating member being connected to and driven by a torque producing device and said secondary rotating member being connected to a torque utilizing device whereby rotation of the primary rotary member causes rotation of said secondary rotating member by some or all of the magnetic flux lines emanating from said permanent magnets mounted on said primary rotating member cutting through the electro-conductive material on said secondary rotary member thereby generating torque and rotation in said secondary rotary member in relation to the percentage of the total area that said secondary rotary member is axially overlapped by said primary rotary member.

a primary torque driving rotary member and a secondary driven rotary member;
the primary rotary member axially overlapping said secondary rotary member;
the secondary rotary member being surrounded by said primary member;
the primary rotary member having electro-conductive elements and magnetically permeable materials neither of which are ferromagnetic, and not having permanent magnets;
the secondary rotary member having permanent magnets mounted on it;
said secondary rotary member axially overlapped by said primary rotating member wherein a means for varying said primary rotary member's axial position relative to said secondary rotating member can be varied; and
said primary rotating member being connected to and driven by a torque producing device and said secondary rotating member being connected to a torque utilizing device whereby rotation of the primary rotary member causes rotation of said secondary rotating member by some or all of the magnetic flux lines emanating from said permanent magnets mounted on said primary rotating member cutting through the electro-conductive material on said secondary rotary member thereby generating torque and rotation in said secondary rotary member in relation to the percentage of the total area that said secondary rotary member is axially overlapped by said primary rotary member.
