If there’s one thing in common between the clocks in our homes and the rolling mills in a paper manufacturing company, it is their alternating current (AC) motors. Consumer products and industrial equipment rely on AC motors due to their ease of operation, low manufacturing cost, and durability. However, not all alternating current motors are the same.
The following guide is a good place to start to identify the different types of AC motors.
Induction motors
The induction motor or sometimes called a rotating transformer creates an electromotive force (EMF) from the spinning electrically charged rotor. The alternating current produced is then converted into mechanical energy.
Induction alternating motors of this kind are also known as asynchronous motors since their rotors spin at a lower level compared to the power supplied to it. Widely used in the manufacturing sector, induction motors are used in automobiles, boiler pumps, and compressors.
Synchronous motors
Opposite to induction motors, the rotor speed in a synchronous motor is parallel to the alternating current supplied thus rotating in a synchronized manner. This design results in maintaining the power of the overall system.
In particular, synchronous motors run in applications where accuracy is crucial such as metering pumps, speed controllers, and high-precision drill machines.
Squirrel Cage motors
Another type of AC motor and a subclass of induction motor, squirrel cage motors are easily recognized with its cage rotors. Instead of a series of coils for conducting current, squirrel cage rotors use solid metal bars through the rotor. In this manner, there is no contact within the rotor mechanism itself.
Squirrel cage motors are commonly used in applications where low maintenance or maintaining a constant speed are desired, for instance, in centrifugal pumps.
The AC Motor You Can Rely On
Considering the importance of alternating current motors across different industries today, selecting the ideal type of AC motor is essential. Furthermore, high-quality AC motors guarantee you smooth daily operations while preventing damage to your equipment due to power surges or normal wear.
