Question

what is the uses of dc motors. ans how to use them

Answer 1

we can do so many experiments with dc motor...!!

it is very helpful...!!

The input of a brushless DC motor is current/voltage and its output is torque. 

As terminal voltage increases or decreases, the speed of the connected DC motor also increases or decreases. ... The AC inverter allows a standard induction motor to be operated at any speed, just like the DC motor. And, it does this without brushes. Brushes are the primary maintenance headache when using a DC motor.
