WHAT TO CONSIDER BEFORE BUYING ELECTRIC ACTUATORS

electric actuators are electrical machines that convert electrical energy into mechanical energy and vice versa. Electric actuators operate on three (3) different principles, namely;

· Magnetic

· Electrostic

· Piezoelectric

The three categories mentioned above operate and function differently in varying dimensions.

The most common one is the magnetic which applies the motoring mode. In this mode there is interaction between an electric motor’s magnetic field and winding currents to generate a linear or rotary force within the electric actuators. In electronic engineering, electric actuators are subdivision of transducers. Electric actuators can be powered by direct current (DC) or alternating current (AC)

When buying electric actuators the following factors should be considered in order to have working and efficient electric actuators:

· Long lifespan

· Low maintenance

· High efficiency

· Low cost

· Simple construction

· Compact high speed

· Reliable ratings

· High power

· Precision positioning high holding torgue

· Low noise

· Low power factor et cetera.

With these factors in view one is sure to have powerful working electric actuators that meet desired needs and where it will be applied for their functionality for maximum output. Besides having good factors in view before purchasing, one should have a good maintenance culture for longevity of the electric actuators.
