Why the armature spins inside a field pole in a dc motor?
because obama
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.
Function of dc and ac motor?
Conversion of electrical energy into mechanical energy
Transfer function of a DC Motor?
G(s)= θ ̇/V= k/(Ts+1)
What is excitation of a DC motor?
DC Voltage
What is the specifications of 5V DC motor?
5V dc motor is the best for the robotics materials and it is inexpensive as compared to the other motors. dc motor is made up of the magnetic coils consist north and south pole

How do you change the speed of motor without change pole and frequency?
On an AC motor you basically vary the frequency on a DC you can vary the voltage.
Function of dc and ac motor?
Conversion of electrical energy into mechanical energy
What is function of dc motor in lift?
Shunt motor is used. For constant speed ,torque will high when load is increased
What is the explanation for the working principle of gear motor?
the gear motor is normally worked by induction and DC motor the gears is the worked of change in motor function
Why does a dc motor develop a high current when starting?
the mechanical force needed to start the motor (move one pole to another) is greater at rest. once forward motion is developed it is easier for one pole to get to the next
When pole flux of dc motor is zero what is its speed?
when the pole flux is zero there is no induced emf in the armature conductor of dc machine as a result of this there is no back emf for controlling action so speed become dangerously high or we can say it will be infinite.
Can one dc motor run the wheel and crank?
yes ,but it need good function geat system and high watt dc motors
Transfer function of a DC Motor?
G(s)= θ ̇/V= k/(Ts+1)
