DC, in DC motor, is an acronym for Direct Current, which means that it works on direct electrical supply by a battery. In an AC motor, the motor runs on Alternating Current Supply from other sources other than batteries, such as electricity from your house.
No, d.c. is not an acronym. It is simply an abbreviation.
"a word formed from the initial letters or syllables taken from a group of words"
http://www.thefreedictionary.com/acronym
Yes, a word. "dc" is not a word.
What else can I help you with?
What is excitation of a DC motor?
DC Voltage
How do you differentiat dc motior and ac motor physicaly?
if you power an ac motor with dc or a dc motor with ac you will likely start smelling smoke and the motor will be damaged. If the motor is marked "3-phase", "shaded pole", or "induction" it is an ac motor! BTW, there are ac/dc motors that will run on both, they are wound very much like dc motors but a bit differently.
Can you convert a DC motor to run on AC?
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
What would cause a meter to read negative voltage across a DC motor?
A DC motor generates power when it is rotating even when no supply is connected.
How is a DC permanent-magnet motor reversed?
Reverse the polarity of armature windings of the motor.
Why synchronous motor called double excited motor?
AC and DC supply sources we are given to motor so we are called double excited motor
The rotating electromagnet coil assembly in a dc motor is called what?
it is called an armature
Why is DC series motor is used more than shunt wound DC motor?
Series DC motor develops a very large amount of turning force called torque from standstill and can be operated by using either an AC or DC power source.
Whether a pmbldc motor is a dc or ac motor?
PMBLDC machine is actually an ac machine and due to power electronics components it's output is dc ,so therefor it is called 'dc'
What is three point dc shunt motor starter?
L , F and A L - Line (connected to Supply) F - Field (connected to field of dc motor) A - Armature (connected to armature of DC motor) that's y it is called 3 point
Which is used to convert DC to ac?
A power switching circuit called an inverter. You could also use an electromechanical motor-generator: DC motor turning an alternator.
What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
What are uses of bidirectional dc motor?
6V dc motor
Why DC motor current ripple?
The induction of a DC motor while rotation lead to a non continuid current. This AC part of the DC csupply current is called ripple current. You can measure this and see if the motor is moving and also you can count the ripple per second and have the motor speed "RMS".
What is dc motor with synchoronous operation?
A synchronous motor is an ac motor that does not run on dc.
When using electronics what device is capable of changing DC to AC?
A device called a power inverter.In old vacuum tube radios an electromechanical device called a vibrator was used.Another device is a motor-generator using a DC motor and an AC generator.
Can a DC dynamo act as a DC motor?
Yes it can and the otherway aroud a DC motor can be used as a dynamo
