Actuators are used in industry to control drive devices. There are modifications on the market that differ in operating voltage and frequency. The actuator circuit consists of a coil, as well as an adapter.

Expanders are mainly used three-pole type. The conductivity of the models is a maximum of 300 microns. In this case, the maximum overload indicator starts from 40 A. The user is able to buy a modification for the drive device at a price of 30 thousand rubles.

How the device works

The principle of operation of the mechanism is based on changing the frequency. First of all, voltage is applied to the coil. At this stage, the current is converted. In this case, the frequency fluctuates around 35 Hz. The adapter serves as an excellent conductor. The motor drives the output shaft. An expander is used to stabilize it. The capacitor is responsible for the harmonic oscillations. Devices are directly connected through contactors.

Using devices

Executive mechanismscan be used on drive units of different power ratings. As a rule, they are installed on conveyors. Models are also actively used in ventilation systems. They are indispensable for adjusting valves. Also, modern modifications can be found on cranes. Some devices are allowed to be installed on plunger mechanisms.

What types are there?

Membrane, pneumatic and hydraulic devices are distinguished by design. Also, the division of modifications is carried out by frequency. Models up to 40 Hz are best suited for low power drives. Their conductivity index is on average 120 microns. There are also models with frequencies over 40 Hz. Their conductivity index is at the level of 150 microns. For powerful drive devices, mechanisms of this type are excellent.
