Title: Magnetic circuit of linear motor drive
Inventor: KINO MASAHIRO
IPC: H02K33/18
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To increase the driving force of a coil by reducing magnetic loss in a main magnetic path, where magnetic flux generated by the magnetomotive force of a magnet flows to reduce the biased magnetic flux density caused by the coil. SOLUTION: A coil 2 is wound around a part of a ring-shaped yoke 1. A magnet 3 is disposed in the part of the inner face of the yoke 1 opposite to the coil 2, so that its magnetic pole lies opposite to the part of the yoke 1 wound with the coil 2. Due to this structure, magnetic flux from the magnet 3 reaches the part of the yoke 1 so as to face the magnet 3 via a gap and then returns to the magnet 3 through the yoke 1, forming a closed magnetic circuit. When current is supplied to the coil 2, the coil 2 moves along the yoke 1. The ring-shaped yoke 1 is made by bonding two U-shaped side yokes 4 with recessed parts counterposed with each other so that a joint part 5 is located at the center of the magnet 3.
