High-Speed Drive Assembly
A direct-drive induction/PM motor turns the rotor through a flexible quill, supported at the top by a magnetic bearing so the spindle floats with almost no friction at full speed. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
