Brake magnet for watt-hour meters

摘要

A generally U-shaped brake magnet for a watt-hour meter molded from a thermosetting resinous material having powdered permanent magnet material embedded in the resinous material only adjacent the surfaces of the legs of the U which form the air gap into which the brake meter disc extends and which may further include reinforcing material embedded in the legs and the base of the U. These reinforcing materials can be non-magnetic metal particles having sharp edges or non-magnetic fibrous material.
