The Main Types of Actuators Available Today
Actuator is basically a motor used to control or generate motion.
The energy required for controlling or
generating motion is obtained from an electric source or from pressurized air.
While a conventional
motor produces rotary motion, an actuator is used to produce constrained motion, like linear actuator
produces motion along a straight line.
The ability of an actuator to produce constrained motion makes it
indispensible for instrumentation and control purposes.
The technological advancement in actuators has
led to the advent of high resolution, precise motion, very sensitive and fast responding actuators.
There
are several different types of actuators available today, prime amongst them are Mechanical actuators,
Hydraulic actuators, Pneumatic actuators, Piezoelectric actuators, Electro-mechanical actuators and
electro-hydrostatic actuators.
Now, let us discuss each of these types in detail.
