Title: ELECTRIC ACTUATOR HAVING MAGNETIC GROUPS MISALIGNED RELATIVE TO MAGNETIC POLE
Abstract:
An electric actuator having magnetic groups misaligned relative to a magnetic pole. The electric actuator comprises an induction coil group (10), and a horizontal magnetic group (20) and a vertical magnetic group (30) which may synchronously move relative to each other are respectively disposed at two sides of the induction coil group; the horizontal magnetic group (20) consists of at least one first magnetic member (21) magnetized along a moving direction, and the vertical magnetic group (30) consists of at least one second magnetic member (31) having a magnetizing direction vertical to the moving direction; the first magnetic member (21) and the second magnetic member (31) are arranged opposite to each other; a switch group (40) is disposed between the induction coil group (10) and the horizontal magnetic group (20), and between the induction coil group (10) and the vertical magnetic group (30) for selectively switching off power of the induction coil group (10). In virtue of the above, magnetic resistance may be eliminated as magnetic members are arranged opposite to each other, so that loss of kinetic energy can be reduced, the rotation speed is increased, and the cutting frequency is enhanced; most of the magnetic current flow through the coil member, and the high flux flowing through a magnetizer can effectively cutting through magnetic wires, thereby enhancing the cutting quantity, to greatly enhance the electricity amount and thus effectively the energy conversion efficiency.
