What do you mean by Electric drives?
elecric drives are basically big electric motors which are used to drive generators
Difference between overload relay and over current relay?
due to the extension of loads they are using the relays for protection.........
Which relay is used to control 3 phase induction motor?
Overloads for motors are sized from the full load amperage that is taken from the motors nameplate. Depending on who the manufacturer of the motor contactor is will govern the sizing of the relay. Some contactors use bolt in heaters and others use a separate unit that connects to the contactor. No matter what method is used make sure to use the manufactures recommended overloads that are based in the motors FLA.
Where are PMSM motors used?
PMSM motors are used in hybrid cars
What are the applications of a shaded pole motor?
When the coil in the relay needs to run off an AC signal rather than DC. The shaded pole keeps the relay from "chattering" every time the AC current crosses 0v on the sine wave.
Are coal and oil motors or generators?
They are neither. Coal is a fuel which can be used to run motors and generators.
Can a motor be used for generator?
Yes, all motors are generators and all generators can be generators. Depending on the type of motor, some are easier to work with. If you mean the common induction motor, you can plug it in and it...
What is magnetism used for like anything?
Magnets are widely used in motors, generators. speakers and many other things.
What are the devices that make used of electromagnet?
AC/DC Motors, Generators etc. are the devices that make Used of electromagnets.
What one converts electrical energy into mechanical energy that is used for work motors or generators?
A generator
What do you mean by Electric drives?
elecric drives are basically big electric motors which are used to drive generators
An electric current produces?
Produces magnetic fields, that are used in generators, inductors and motors. The magnetic field at any given point is specified by both a magnitude and a direction.
Difference between overload relay and over current relay?
due to the extension of loads they are using the relays for protection.........
What is a control test tube?
There are many uses of the electromagnet, it is used to invent generators and electric motors, used it to control the switch relay, use in practical industries, and even in an electric bell etc. Because the electromagnet is a type of magnet in which the magnetic field is produced by the electric current.
What kinds of motors can work as generators?
Some types of dc (direct current) motor can be used to generate dc, in which case they are often called 'dynamos'. Some alternating current (ac) motors can be used to generate ac, in which case they are called 'alternators', but many types will only work as motors. For instance, a squirrel cage ac motor cannot be used as an alternator.
What is an Induction Relay with shaded pole?
It is a device used to protect Electric Network and loads
What is the dynamic brake used for on a diesel locomotive?
The electric motors that drive the locomotive can be re-wired as generators (by throwing a switch). The motion of the train can then be used to generate electricity - which is used to heat a large resistor to disparate the heat.
