DC and AC Motors: Which Motor Is Right For You

Knowing what type of motor you will need can be a daunting task due to the fact that there are a lot of types of motor available in the market today. So before you place an order there are a lot of restrictions that needs to be addressed. So how will you be able to properly know all these? With the help of this article, you will be able to determine what type of motor that is best for you.

 

First of all you need to know what the available voltage source for your application is. Electric motors can either be alternating current or AC and direct current or DC. The AC or alternating current runs on AC voltage while DC runs on DC voltage. There are available universal motor that runs on both voltages AC and DC.

 

As soon as you have established the power source, the next thing you need to determine is which style that will work best for your application. AC motors can be subdivided into a single phase induction, three phase induction, two phase servo and hysteresis synchronous. DC can also be subdivided into brush DC, brushless DC and Stepper types.

The next you need to understand is the different characteristics in each type to properly match the motor to its application.

 

Single phase induction motor can be connected in a single voltage line while an external capacitor is required in order to make the motor work. The different type of single phase induction motors can be distinguished on which method they started. There are 4 basic types which are capacitor start, split phase, permanent split capacitor and capacitor start and capacitor run.

 

For a split phase motor it uses a switching device in order to disconnect and start winding as soon as the motor get 75% of its speed. This type has single design that will make it cheap for commercial use as well as it uses a low starting torque and high starting currents.

Capacitor motor can basically split phase capacitor motor that has a capacitor series with starting winding for it to create more torque. The only problem with this type of motor is that it is expensive due to switching and capacitor requirement.

 

Permanent split capacitor does not have starting switch. For this type, a capacitor permanently connected to start winding and because the capacitor requires continues use, it does not provide start power. Click here to get started!
