Why Use An AC Motor?

Efficiency – AC motors have a high speed to torque characteristic, which offers excellent performance without overheating, braking, or degeneration. The performance of AC motors is why they are used in high demand applications. About 85% of the incoming energy is used to create the outgoing mechanical energy.

 

Lifespan – AC motors last in the most demanding of conditions. The only component that may need to be replaced are bearings, which is a simple, easy, and affordable repair. AC motors have two bearings that have to be periodically lubricated. The durability of AC motors is one of the reasons that they are chosen for off road applications or use in rigorous conditions.

 

Quiet – Since AC motors have a very low sound output, they are chosen for commercial environments where food is being served or customer service is essential. The sound that AC motors produce is a low hum.

 

Adaptability – There are several factors that make AC motors adaptable and flexible. They are powered on using a simple on and off switch, which can be reversed. An additional factor is their variable speed and power output that makes them adaptable to conditions where there are multiple users.

 

Accessibility – Every industrial operation has a variety of conditions that require multiple sources of power and energy. Since AC motors come in several shapes, sizes, and different power outputs, they can easily be fitted to any possible situation or be customized and designed to fit specialized and unique conditions.

 

Simplicity – The fact that an AC motor has only one moving part is a major benefit to their use. The stator of an AC motor is the same for asynchronous and synchronous motors. This simplicity of design is the reason that they are quiet running, low cost, and long lasting.

 

Brushless – A brush motor uses brushes and a commutator to supply electricity to magnetic coils on the armature. This process creates friction, heat, and a loss of energy. A brushless motor, AC motor, eliminates the brushes and commutator, which creates a cooler and more efficient motor that has less wear.

 

Self-Starting – Only AC excitation is necessary to operate an AC motor. The simplicity of the starting mechanism does not require any additional component for an AC motor to start.

 

Speed Regulation – The speed of an AC motor can be controlled by changing the frequency that is sent to the motor, which causes it to speed up or slow down.

 

Single Phase Input – Part of the adaptability of an AC motor is how it can run using a single phase input for a three phase motor even though the location may not have a three phase input.
