AI, MI series of intelligent electric actuators are driven by a
three-phase asynchronous motor, decelerated by a worm gear, and
drive the hollow output shaft to output torque. The reducer has a
hand/electric switching mechanism. When the switching handle is in
the manual device, the handwheel drives the hollow output shaft to
rotate through the clutch: when it is electrically operated, the
switching mechanism will automatically fall back to the electric
position, the clutch and the turbine mesh, and are driven by
three-phase electric The hollow output shaft rotates.
The rotation of the output shaft of the actuator is transmitted to
the Hall effect pulse sensor through the speed increasing
mechanism, and the axial displacement generated by the axial force
of the motor worm is transmitted to the mechanical torque control
mechanism (switch mechanism) to achieve valve position and torque
control.
The intelligent controller of the electric actuator accepts
standard analog current control signals or switch control signals
or bus signals, and positions the output shaft of the actuator at
the position corresponding to the input signal; it can also be
based on interlocking control, two-wire control or The emergency
ESD event signal is located at the preset position of the control
system.
