ELECTRIC ACTUATOR HAVING MAGNETIC GROUPS MISALIGNED RELATIVE TO MAGNETIC POLE

WIPO Patent Application WO/2018/205216

A1

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 consists of at least one first magnetic member (21) magnetized along a moving direction, and the vertical magnetic group consists of at least one second magnetic member (31) having a magnetizing direction vertical to the moving direction; the first magnetic member and the second magnetic member are arranged opposite to each other; a switch group (40) is disposed between the induction coil group and the horizontal magnetic group, and between the induction coil group and the vertical magnetic group for selectively supplying power to the coils. In virtue of the above, an induced voltage can be eliminated when no power is supplied, the electric actuator is driven by lower power, and magnetic aid can be generated during power transmission driving, so that output kinetic energy is enhanced, and the purpose of significantly improving the energy conversion rate is achieved.
