What is the role of split rings in electric motors?
Split rings keep the current flowing in the same direction or the motor turning in the same direction when using alternating current which reverses direction in its cycle..
What type of current is used in an electirc motor?
Well that depends on the type of motor. DC motors use direct current DC and induction motors use alternation current AC.
How to control the starting current of motors?
the starting current of motors can be controlled by using an additional resistance in the beginning and gradually decreasing it.Motor starters do the same
How many current sensing devices are required by the National Electrical Code to protect a single-phase motor operated on 240 volts?
For a single phase fractional horsepower motor, only one over current device is needed in the motor feeder. This protection can come in the form of a switch which has the overload heater incorporated into it. These switches come in single and double pole configurations. Select the heater for the motors full load current that is taken from the motors nameplate. Search the web for "fractional motor starter switch".
What is meant by DC motor?
Only a DC motor uses direct current, and the reason is that it is the only supply available. There are also plenty of AC motors used when there is an AC supply. DC tends to be used for low-power devices like fans in electronic equipment.
What component of a motor changes the induced AC voltage into a pulsating DC?
The commutator is the moving part of the electrical switch in motors that reverses the current direction between the rotor and the external circuit. This is applicable in electrical motors and electrical generators.

Can you switch motors on a 1985 quad to a 1988?
You can not swtich the motors out in a 1985 Quad and a 1988 Quad. The reason you can not swtich the two motors is because they are not comatable with each model.
What is the current stock symbol for General Motors?

Can ac motors run on low dc current?
No.

Why noload current in big motors is higher than load current?
That is not always true.
What is the type of switch that reverses the rotation of a single phase motor?
If you are talking about a switch that is used to change the direction that a single phase motor turns from clockwise to counter clockwise, the switch is called a forward - reverse drum switch. By reversing any two of the three phase legs that feed the 3 phase motor. <<>> On a single phase motor a drum switch is used. This switch reverses the start winding so that when voltage is applied to the motor it will revolve in the reverse direction.
