i want to know about torque of slip ring induction motor
If oil and air can withstand a high MeV when used as an insulator in a transformer, what are the values of how high for each material?
hi every body i am master student in control engineering and my project is slip control in trains i assumed a Dc motore as traction motor but i don't have characteristics of this kind of motor that is used in train. i want from every body if he or she has the characteristics or information about Dc motor that is used in train give me those information or technical characteristics .
What should be the values of settling time, peak time, steady state error, overshoot, rise time, MPOS (Maximum percent over shoot) to keep the system in transient state, to keep the system in steady state ?
