Claims

[Scope of utility model registration request]

An electric actuator that uses electromagnetic action to stop the rotation of a rotor at two positions separated by a fixed angle.A stopper plate is fixed at a fixed interval to a rotor plate to which a magnet and a shaft are fixed, and a yoke fixed to a base is used. Rubber pads with plate ends made of magnetic material attached to both end faces are fixed at a certain angle to the stopper plate, so that when the stopper plate rotates, it comes into contact with the plate ends and stops, and is held by suction at the stop position, and , a switch plate with copper foil pasted on the rotor plate is fixed, and a pair of brushes is arranged on the base side, and at one stop position of the rotor plate, both brushes are positioned on the copper foil to operate the switch. An electric actuator for two-position stopping, characterized in that it is provided with a detection mechanism for confirming the stop position in which one brush is not located on the copper foil when the switch is closed and the other stop position is open.
