a dc series motor drives a load, the torque of which varias as thesqure of speed. The motor takes a current of 15 A when the speed is1500 rpm. Calculate the speed and the current when the motor field winding is shunted bya divert or of equal resistance as that of the field winding.Neglect all motor losses and assume the magnetic circuit a sunstaturated.
Discuss the statement "If you were a historian, what kinds of documents and artifacts would you study and then write about to help people in the future to understand the events of September 11, 2001."
A positive charge of 625 nC is uniformly distributed around a circular ring of radius 3 m that is positioned in the x-y plane. The center of the circle is at the origin. The relative permittivity of the medium is Epsilon_r = 1.
what is the common mode of starting the synchronous motor. Explain the function of the damper winding popularly called as the "amortisseur winding". Indicate all circuit diagrams to explain working of the synchronous motor.
On Earth, we assume normal room temperature is 293 degrees Kelvin. From this, we find that the power spectral density of thermal noise is -174 dBm/Hz. On Venus, the average surface temperature is 462 degrees Celcius.
