Making the Most of DC Motors

Getting the best DC motors for the application

By Marjorie Gilbert
Direct current, also known as DC, motors are some of the first motors designed. The direct current refers to the method in which the power transfers to as well as through the motor. DC electric motors work very well if you need to maintain a certain speed, which is why one can find various electric motors for automobiles and toys. DC motors can come in various forms: DC servomotors, DV gear motor or gearmotor and DC power systems. As one might imagine, the design varies for each DC motor applications.

Making the most of DC motors means finding the right DC electric motor for the right DC motor applications. For example, DC electric motors for cars would not work well when you need DC servomotors. To help guide you, consider these options:

1. Use the DC gear motor for large and small applications.

2. Rely on DC power systems for portable power needs.

3. Let DC servomotors power industrial applications.

 

Explore applications for a DC gear motor

The DC gear motor is prized because of its torque and power. You can find that they are the electric motors for autos, as well as the DC motors opening and closing great glass roofs at the Lincoln Park Zoo in Chicago, Illinois. The DC gear motor comes in various torques and speeds, which allows you to match the torque needed to the task. For example, the torque for the electric motors in automobiles would not be the same as the one opening the Lincoln Zoo's roof.
Try: Two manufacturers of the DC gear motor are Bison Gear and Engineering and Bodine Electric.

Let DC power systems provide power for you when you're on the go

DC power systems work for portable devices like portable cash registers, wireless computers, printers, scanner carts and more. Often, these systems include DC-to-DC inverters, inverters for DC-to-AC, built-in chargers and other options. Some of the DC power systems are for use underwater at limitless depths.
Try: Two providers of DC power systems are CameronDC and Storage Battery Systems.

Rely on DC servomotors for heavy duty applications

These direct current motors are designed to withstand demanding requirements of industrial motion control. They can be for use in brakes, shafts, tachometers, connectors and more. They also have a long life, despite the ruggedness of their applications.
Try: The Electric Motors Reference Center has a good definition of servo motors, as well as their application. One of the many manufacturers of DC Servo motors is Baldor.
