Applications of Dc motor (dc motor applications everywhere)
applications of Dc motor
We perfectly know that Dc motor is an electrical device which converts electrical power into mechanical power and from this point we can find many applications of Dc motor; from the name, these types of motors run on Dc power which is an easily available source so it can be used in toys as it can be designed in small size, and as we said Dc motor has a good speed regulation so we use it lifts, suburban trains, electric traction and so on when we require a good speed control characteristic.
And as it also has a constant or low-speed torque we use it in dynamic braking and reversing applications.
And as we know there is more than one type of Dc motor, we deduce that we can find Dc motor everywhere depending on the type as:
Applications of Dc series motor:
Dc series motor is the best of Dc motors because it is suitable for both high and low power drives, for fixed and variable speed electric drives, it has a simple construction, it’s easy to design and maintenance, and it also has a high starting torque we find it in cheap toys and automotive applications like:
- Electric traction.
- Electric footing.
- Air compressor.
- Winching systems.
- Versatile electric equipment.
- Hair drier.
- Vacuum cleaner, and so on where we also need a variation in speed.
- Sewing machines and power tools.
Applications of Dc shunt motor:
We know that Dc shunt motor is a constant speed motor so we use it where we need almost constant speed from no load to full load like in:
- Automotive windscreen.
- Lathes machines.
- Boring mills.
- Centrifugal pumps.
- Spinning and weaving machines.
Applications of separately excited Dc motor:
Separately excited Dc motor or as you remember permanent magnet Dc motor is a special type where we use a permanent magnet to create the required magnetic field and we also know that it doesn’t need to control the speed so it’s usually used in:
• Automobiles as a starter motor.
• Blowers in heaters and air conditioners.
• Personal computer disc drives.
• And also in small fractional and sub-fractional KW motors.
Applications of compound Dc motor:
We have two types of the compound motor the first is differential compound and we rarely use it because it has poor torque characteristics and the other is the cumulative compound which has a high starting torque and good speed regulation at high speed so it’s the most used in:
- Electric shovels.
- Reciprocating machine.
- Stamping machine.
- Rolling mills.
- Heavy planners, and so on.
Applications of brushless Dc motor:
As we said brushless Dc motor is a special motor because it doesn’t contain brushes, has high efficiency, high speed, and electronic control so we use it in many applications like:
- In computer peripherals (disk drives, printers).
- Hand-held power tools.
- Consumer electronics.
- Heating and ventilation.
- Vehicles ranging from aircraft to automobiles.
- For Small cooling fans.
- And for gramophone records in direct-drive turntables.
its clear that applications of Dc motor are everywhere around us in homes, workshops, factories and so on which make it very important to us.
