Is the current produced by a dc motor the same as the current given to it?

A motor uses electricity; it does not produce it. If you are somehow using a DC motor as a generator, then it will produce power equal to the input power minus the motor losses. If the input power is you spinning the rotor, the output power will be directly proportional to how much work you put into spinning the rotor.

In synchronous motor theory is excitation current the same as field current?
yes. excitation current is same as field current to my knowledge
What is shaft motor?
It is the same thing as the motor's rotor speed given in revolutions per minute.
What does the split ring commutator do in a motor?
It generates a alternating current to keep the motor rotating in the same direction.
What is motor shaft speed?
It is the same thing as the motor's rotor speed given in revolutions per minute.
What type of diesel fuel for older diesel motor?
The same type you use in a current production diesel motor...
What is locked rotor in three phase induction motor?
A motors locked rotor current is the same as the motors starting current. This is the point where the voltage is applied to a non rotating motor, time cycle zero. Because the motor is not rotation and generating a back EMF to oppose the inrush current, the current will go as high as 6 times the running current of the motor.
What is the definition of direct current?
(a) A current flowing in one direction only; -- distinguished from alternating current. When steady and not pulsating a direct current is often called a continuous current. (b) A direct induced current, or momentary current of the same direction as the inducing current, produced by stopping or removing the latter; also, a similar current produced by removal of a magnet.
What you basically want is will each phase take 26 Amps current for 15HP 3 phase 415VAC motor?
Yes. In a 3-phase motor, all 3 phases have the same current.
Why starting currrent is higher in 3 phase id motor than 3 phase transformer?
CLARIFICATION AND ANSWER: 1. STARTING CURRENT PRODUCED ONLY BY ITS LOAD NOT SOURCE(SAY STEPDOWN TRAFO) 2. IF THE INDUCTION MOTOR IS THE ONLY LOAD OF THE STEP DOWN TRANSFORMER (SOURCE)-THE READING WILL BE AND SHOULD BE THE SAME IN THE SECONDARY SIDE UNLESS YOUR AMMETER IS IN THE PRIMARY SURELY WILL READ LOWER BUT POWER CONSUMPTION REMAINS THE SAME. 3. IT ALSO DEPENDS ON THE RATING OF THE MOTOR LOAD AND THE TYPE OF STARTING METHOD USED THAT YOU CAN MEASURE STARTING CURRENT.
What is the phase current of a three phase 2.2kw 415v motor connected in star?
The line current would be the same if the motor were connected in delta. The current can be based on the rule of thumb which says 7 amps must be allowed for a 1-HP single-phase motor on 240 v. A 2.2 kW motor is three times as powerful, and on a three-phase supply of the same voltage (240/415) it would draw 7 amps.
Why less current increases in transformer than in induction motor when load is increase?
The current flowing through a transformer's secondary is the current drawn by the load, so it will be exactly the same as the current flowing through your induction motor -assuming that is the load. Don't really understand the point of your question!
How do you increase parallel paths in lap wound motor?
parallel paths are conductors where current direction is same
