What Are The Advantages of Variable Speed Motors?

Aug 26th 2022

Everyone knows the word motor, but only a few people know about variable speed motors. Usually, two types of motors are available in the markets, i.e., single speed and variable speed. The variable speed motors are reliable and more convenient because they change their speed according to the instructions given to them. The procedure is similar to a light bulb which can dim or shine brightly. In particular, the supplied power is changed to change the speed of the motor.

Undoubtedly, variable speed motors are very advantageous for the appliances or industrial work. The reason is that you can control the working through instructions, unlike the traditional motors. This guide will tell you the major advantages of variable speed motors that everyone can enjoy. Let's begin!

What Is A Variable Speed Motor?

A variable speed motor is an ordinary motor that can run at different speeds. It usually takes air from the air conditioner and circulates it in the environment. It can run at different speeds and be used for different applications such as HVAC blower motor and more.

Benefits of Variable Speed Motor or VFDs

The advantages of VFDs at industrial level are:

Extended Life

When each operation of a motor is managed precisely, it's very useful to extend the motor's life. When you leave all the heavy lifting onto the motor, it demands more power to work. With the increased power, the temperature of the motor increases, which accumulates over time.

On the other hand, this phenomenon also increases the strain on the windings. The VFDs allow the motor current to rise gradually without any surges. In this operation, the motor mechanism runs smoothly and keeps your motor safe.

Balanced Current Flow

When the current flow changes suddenly in a motor, it affects the power line feeding system of the motor. It is observed that when you provide more current, it becomes capable of handling more load. However, the drawback is that the surge power increases in such a way; that it's not good for the system. It can affect the other components in the system, such as computers, proximity switches, various sensors, and more. On the contrary, VFDs allow the current flow in a balanced manner that is not harmful to the system.

Precise Speed Control

The VFDs change the motor speed precisely without any surges. This system is very useful for many systems, such as conveyor systems and others. Variable speed motors are extremely useful for HVAC systems, conveyor systems, and more. You can control the speed of the motor according to your needs and requirements; that's a plus.

Design Efficiency

In many systems, using VFD eliminates the use of many other components. You can drive many systems smoothly without gear usage. In short, a VFD system is economical and can reduce several components in a system. In terms of design efficiency, variable speed motors bring many benefits. For example, lower startup power requirements, reduction in power line disturbances, precise control over speed, acceleration and torque output, cost-saving procedure over time, and reduced energy consumption. All these things increase the overall efficiency of the system.

Cost-saving

Recall that the VFD system does not allow the motor to withdraw current beyond a certain limit. In such a way, all the functions are limited and controlled by threshold values making the overall system cost-effective. Yes, variable speed motors do not burden your pockets in terms of electricity bills and bring many other benefits. So, if budget is your top priority, having variable speed motors is crucial.

Conclusion

To sum up, a variable-speed motor is always more advantageous than a single-speed motor in several ways. It lowers the electricity bill, can be used for multiple applications, and gives a long-lasting performance.
