Abstract
The utility model relates to an inner-magnetic type permanent magnet actuator. A magnetic loop is formed by a dynamic iron core and a static iron core; the longitudinal section of the static iron core is E-shaped; the central column of the static iron core is connected with a permanent magnet and a magnetic yoke in sequence through a non-magnetic screw; an electromagnetic coil is sleeved on the central column of the static iron core; the permanent magnet is positioned in an inner cavity surrounded by the electromagnetic coil. A magnetic path gap between the magnetic yoke and the dynamic iron core can be changed by changing the thickness of the magnetic yoke, thereby changing a magnetic holding torque of the inner-magnetic type permanent magnet actuator and improving the dynamic stability of a contactor. The inner-magnetic type permanent magnet actuator has the advantages of simple and clear structure, small volume of permanent magnet, convenient assembly, and mature technology. The prior contactor can be produced without reconstructing the production line of the prior contactor; at the same time, because the magnetic holding torque can be changed by changing magnetic yokes with different thicknesses, the technical parameters of the contactor product is very convenient for being adjusted during organizing production.
