Homopolar motors work on a principle called the Lorentz force law, the same principle that makes a rail gun work. They are the most basic and conceptually simple rotary electric motors possible. You may also see them referred to as Faraday Disks, or unipolar motors. Because they are so simple, they have the potential to be very efficient, but unlike AC (alternating current) induction motors, AC synchronous motors, or DC (direct current) brushless motors (the latter two are essentially the same), they require brushes, and therefore more maintenance. They also tend to work at low voltage and high current, which makes the brushes more lossy. My best guess is the problems with the brushes are why homopolar motors appear to have never found any commercial or military applications. However, a quick search on Google will show that the Navy is interested in using them on ships and subs. Because they are the only truly DC motor, they should prove to be quieter than any other electric drive option they are considering. AC motors come with a lot of noise, just ask your washing machine.

What is zero sequence impedence?
Zero sequence impedance indicates a homopolar symmetrical component. It is a term used in electrical engineering within a three-phase system of linear combinations.
Different uses of motors?
Motors are used in a variety of appliances and industries all over the world. Washing machines, dishwashers and electric fans all have motors. Motors are also found in milling machines, hand drilling machines, and gas pumps.
Why commutator are not used in ac motors?
Because, the commutator segments are used for converting AC to DC.
Elevator driving motors used with a generator field control are rated as?
Elevator driving motors used with a generator field control are rated in kVA. This is a unit of electrical power that is often used to measure the capacity of elevator motors. ESCON Elevators uses generator field control motors in their elevator systems, which are known for their high efficiency and reliability. If you are looking for an elevator system that is both efficient and reliable, then ESCON Elevators is a great option
What types of motors are used in escalator?
slip ring induction moters is used due to its high starting torq
Can homopolar magnet work with any type of magnet?
Yes that works but first you should design a homopolar magnet because there are no homopolar magnets built, yet !
What will a homopolar motor do?
well a homopolar motor turns. (to say it bluntly) its all thanks to an electrical current flowing through a magnetic field.
Where are PMSM motors used?
PMSM motors are used in hybrid cars
Why is iron used for motors?
because it is light and it is good for motors
Who owns Vauxhall motors?
It used to be General Motors. Now it is anyone's guess!!
What are city motors used for?
City motors are used for pumping water throughout the city. Without city motors, water would not flow to households. It's important to remember that city motors require maintenance to operate.
What is zero sequence impedence?
Zero sequence impedance indicates a homopolar symmetrical component. It is a term used in electrical engineering within a three-phase system of linear combinations.
What are the types of hvdc systems?
There are 3 types 1) monopolar 2)bipolar 3)homopolar
What is GM used for?
General Motors
Does oil lubricate motors?
Yes, oil is used to lubricate internal combustion engines. Grease is used to lubricate electric motors. =========================================================== I have always used non detergent oil in my ELECTRIC MOTORS and grease for the bearings if there is a grease fitting
Are coal and oil motors or generators?
They are neither. Coal is a fuel which can be used to run motors and generators.
Where is magnet wire used?
Windings for motors.
