DC Motors
Tips & Advice to help you make your decision on DC Motors
DC Motors
DC electric motors use direct current electricity as their source of power. As one of the earliest motor designs, many people can quickly grasp how one works. This can be advantageous to you if you work on the motor. However, DC motors can be larger than other motor types and require extensive maintenance.
The three types of DC motors are brush, brushless, and uncommutated motors. Brush DC motors use fixed magnets, commutation, and rotating electrical magnets to create torque. Brush electric motors are prized for their easily controlled speed and low starting cost. However, maintenance fees can quickly erode savings. The brushes and springs within the DC motor may require regular replacement depending on the amount of times you use the motor.
Brushless DC motors use a rotating magnet and stationary electrical magnets. The design is simpler than brush motors, but there is a higher initial cost. Brushless motors also require far less maintenance and are more efficient.
Uncommutated motors, such as the homopolar motor or ball-bearing motor, do not require commutation. Homopolar motors have limited applications because the voltage is restricted. Ball-bearing motors use a flywheel, two ball-bearing assemblies, and a shaft to produce movement.

Using DC Motors
Get the right DC motors for the jobBy Marjorie Gilbert DC motors, like practically anything, can fit certain applications. Whereas they all share the characteristics of being powered by DC or direct current, it's also true that not all DC motors work for all applications. Just as a Shetland pony would not fare well in a race against thoroughbreds, a DC gear motor would not work well in deep water applications.
Using DC motors means matching the right DC motor to the job, whether it's electric motors for autos or for different applications. Below, you'll be able to browse through information about various DC motors and their specific DC motor applications. You can also find information about DC motor producers or manufacturers as well. Consider these tips when using DC motors.
1. Use the DC gear motor when uninterrupted service is required.
2. Utilize DC power systems when you need portable power.
3. Employ DC servomotors when you need industrial power.
Look for consistency from the DC gear motor
The electric motors for automobiles are generally the DC gear motor. This is because they are consistent and long-lasting. But DC electric motors for cars are not the only application. These DC gear motors work well in vending machines as well as business equipment, cordless tools and more. The voltage for these DC gear motors can range from 12 to 24 volts, and the torque range from 25 to 5000 mNm.

Buhler Motor and Motor Tech are two manufacturers of DC gear motors.
Let DC power systems give you power on the go
DC power systems are handy tools for portable devices like crash carts. They are also wonderful in that you can have them custom-designed by the manufacturer to fit your company's needs. You can decide the number of outlets handles, test points, meters and more.
Try:
Acopian Technical Company and Power Magic are two of the many manufacturers of DC power supplies.
Apply DC servomotors for industrial power
DC servo motors are different from electric motors in automobiles in that they stop on a dime yet provide strong, consistent power. They're in use in computers, and "closed loop control systems" as well as other DC motor applications.
Try:
BDI and Industrial Drive Components are two manufacturers of the DC servomotors. The MathWorks has an interesting article about estimating the parameters of a DC servo motor.
- Direct current (DC) motors are valuable tools that work for many applications. If you do not find a DC electric motor that doesn't exactly fit your needs, contact the manufacturer. You will find that the manufacturer will work with you to create custom direct current motors that will better meet your company's needs.
