Abstract
An apparatus for magnetizing selected portions of a shaft in a substantially circumferential direction includes a fixture mounted onto the apparatus adapted to receive a shaft to be magnetized, at least one magnetization head, the magnetization head being mounted moveably on the apparatus such that the magnetization head can be moved radially relative to the fixture, a plurality of brushes mounted onto the magnetization head, each brush having a distal end defining an internal diameter sized to circumferentially contact the shaft, the brushes being spring-loaded such that when the magnetization head is moved toward the fixture, each brush engages the shaft with proper pre-load force, and a buss bar, wherein the brushes are electrically connected to the buss bar for even distribution of electrical current to the brushes.
