To fully appreciate the chief advantages of linear motors, it is helpful to compare them to ballscrews, another high-precision rotary-to-linear transmission system. Although typical ballscrews are ...
Linear motors are synchronous motors: Current is applied to the coil to form an electromagnet. The coil then synchronizes itself to the magnetic field generated by the permanent magnets in the magnet ...
The levitation type linear motor car is based on the basic principle that it repels with and attracts to the magnet by switching between two magnetic poles of N pole and S pole with electromagnets.
