Wound-field dc motors are common in small household appliances such as vacuum cleaners, cordless power tools, and food mixers. Their only drawbacks are that they’re noisy and exhibit wear (at the brushes) so don’t work well in applications with high duty cycles.
Where can we find DC motor at home?
Many small motors can be found in cars for power windows, heating, cooling fans, and windshield wipers. Motors can also be found all around the house, especially for slow-moving, high-torque functions. Kitchen appliances like blenders and mixers use electric motors.
What devices use DC motor?
At home, small DC motors are used in tools, toys and various household appliances. In retail, the applications of DC motors include conveyors and turntables, while in an industrial setting, large DC motor uses also include braking and reversing applications.
Where are DC motors used in everyday life?
Direct current (DC) machines have numerous applications. These applications range from our daily life to spacecraft applications. In our daily life, they are used in printers, fuel pumps, and electric vehicles. While in spacecraft applications, they are used in solar airplane, electric aircraft, and propulsion systems.
What common household devices use motors to work?
The electric washing machine, invented Alva J. Fisher in 1906, is a common home appliance that makes use of an electric motor. Other home appliances that use electric motors include clothes dryers, vacuum cleaners, fans, air conditioners, refrigerators and freezers.

What is the speed of DC motor?
DC controls adjust speed by varying the voltage sent to the motor (this differs from AC motor controls which adjust the line frequency to the motor). Typical no load or synchronous speeds for an AC fractional horsepower motor are 1800 or 3600 rpm, and 1000-5000 rpm for DC fractional hp motors.
What is the importance of electric motor in our daily household chores?
Electric motors are extremely important in modern-day life. They are used in vacuum cleaners, dishwashers, computer printers, fax machines, video cassette recorders, machine tools, printing presses, automobiles, subway systems, sewage treatment plants, and water pumping stations, to mention only a few applications.
