Abstract

826,048. Electromagnetic brakes. BRITISH THOMSON-HOUSTON CO. Ltd. Nov. 20, 1957 [Dec. 7, 1956], No. 37504/56. Class 35. In an eddy-current brake wherein the rotor comprises two spaced discs with inner faces shaped to induce air currents between the discs, the stator has radial slots providing air passages and forming concentric sets of polepieces magnetized by a single coil and cooperating with the outer face of each rotor disc. As shown, an annular slot 14 separates the separate sets of stator polepieces 15, 16, and individual polepieces are separated by radial slots feeding air to the rotor inlets 11. The ribs 8 on the rotor discs 3, 4 interleave with one another.
