PROBLEM TO BE SOLVED: To build a simple linear motor for toy which surely operates while the number of parts is made small as much as possible, and the motor is simplified. SOLUTION: A solenoid coil and a lead switch are installed in a long plate-like rail which becomes a stator. A permanent magnet is installed in a moving element, and a thrust is generated only by a resilient magnetic force of both the moving element and the stator. COPYRIGHT: (C)2006,JPO&NCIPI
