Picking The Best AC Motor

The AC motor is one of the most common types of motors used in a variety of applications. Perhaps it runs off the AC voltage readily available in wall outlets. It is usually built with a wound stator with a rotor and consists of a shaft, cast aluminum, and laminations. It is the stator winding that influences most of the performance characteristics of the motor. So, why is it so important that you pick the most suitable motor for your application?

In general, there are three most common types of single-phase AC motors available out there. These are the permanent split capacitor, capacitor start, and split phase. Now, when it comes to the specifics of the AC motor, its output speed comes relatively fixed which depends on the number of poles with which the stator is wound and the frequency of the input voltage. However, the value of the input voltage in this kind of motor does not impact its speed which is the case with DC motor.

In any case, you need to know that when deciding on a single-phase AC motor, you will have lower starting torque than its actual rated torque. This concern is critical because if your application for a motor requires starting right with a load, then it might be a better option to choose a three-phase motor instead.

Moreover, three-phase AC motors also offer better seed regulation when control is utilized and they can provide for either higher or lower speeds. In ideal scenarios, the motor’s optimal efficiency will be close to the motor’s operating torque. This is why you have to carefully consider the requirements of your application before you can finally choose which type of AC motor best fits it.
