Different Types of Motors and How They’re Used
Monday, March 4, 2019

When you are considering the purchase of motors, one of the things you need to figure out is whether to go for an AC motor or a DC motor. The thing is, choosing the right kind of motor actually depends more on the intended application and the cost involved with it, more than anything else. Both AC and DC motors have their advantages and your choice depends on how you plan to capitalize on them in your industrial application.

AC Motor

AC motors and DC motors are different in a lot of respects. AC motors are highly flexible in many regards including the fact that you can control the speed of their rotation. They have Variable Speed Drives which enable you to do that. They also happen to have a much larger control base than DC motors. Here is a look at some of the advantages of using AC motors:

They require less power when they start, their acceleration can be controlled and they have an adjustable speed while operating. You can adjust the torque speed based on the requirement. In addition, they can function on a controlled starting current and do not cause a lot of disruption in power lines. The most common type of AC motor is the induction motor. It relies on electromagnetic induction from the magnetic field of the stator winding. It uses the induction to create a magnetic current in the motor which in turn results in torque. Three-phase induction motors are commonly found in industrial applications through conveyer systems, pumps, compressors and lifting gear.

DC Motor

DC motors were the first kind of motor to have been developed. They were used throughout various industrial applications. DC motors have a comparatively low initial cost when it comes to the low power units. The high power units increase the overall operational costs considerably. The speed for DC motors can also be controlled to a certain extent, depending on the voltage of current flowing through them. Here is a look at some of the advantages that DC motors offer in comparison to AC motors:

The installation of DC motors is a lot easier as compared to AC motors. This is because of their smaller control base. They also offer speed control, which can cover a wide range depending on voltage input. They provide a high starting torque, they start faster as well. You can just as easily stop the DC motor and reverse them based on your needs with quick response.

DC motors are typically used in speed and positional control in applications spanning from pumps, compressors and fans – all applications where there is the need for certain ruggedness in the motor.

Bottom Line

The choice between AC motors and DC motors is not about which one of these is better than the other. Rather, the choice depends on how you plan to use the motor and the overall cost of operation and maintenance.
