Abstract
A magnetic levitation actuating motor includes a hollow base externally wound with a coil, at least one magnetic element fixedly mounted to at least a free open end of the hollow base, and a magnetizable actuator axially movably disposed in the hollow base. When the coil is supplied with a current to produce a magnetic flux, the magnetizable actuator is temporarily magnetized to produce a magnetic intensity, so that the magnetizable actuator and the magnetic element mutually attract or repulse to displace the magnetizable actuator in the hollow base. When the current supplied to the coil is cut off, the magnetizable actuator can still maintain at a balance point position in the hollow base for a period of time. Therefore, by intermittently supplying current to the coil, the magnetizable actuator can stay at the balance point position over a prolonged time with reduced power consumption.
