A 3300 V, 3-phase, 50 Hz, star-connected synchronous motor has a synchronous impedance of 2+j 15 ohms per phase. Operating with a line emf of 2500 V, it just falls out of step at full load.
A 3300 V, 3-phase, 50 Hz, star-connected synchronous motor has a synchronous impedance of 2+j 15 ohms per phase. Operating with a line emf of 2500 V, it just falls out of step at full load. a) Draw the equivalent circuit of a synchronous motor. b) To what open-circuit emf will it have to be excited so that it will just remain in synchronism at 50% above rated torque? c) With this emf , what will then be: the input power; current; and ...
The equivalent circuit parameters of a 440 V, 3-phase, 8-poles, and 50 Hz star connected motor (HELP)
Question: The equivalent circuit parameters of a 440 V, 3-phase, 8-poles, and 50 Hz star connected motor are given below. The short-circuit test is conducted with a locked rotor and a line current of 80 A. The open-circuit test is conducted by supplying the stator winding at rated voltage and at the same time driving the rotor in the same direction as the rotating field, at synchronous speed; s=0.R1 = 0.1, X1 = 0.5, RI2 = 0.1, XI2 = 0.5, Xm = 20, Rm = 100...

The motor of your "dune buggy" is fueled by a gas line with a
radius of 4.00 10-3 m and the fuel pump is rated at
5.45 10-2 kg/s. If the density of the gas
you are using is 730 kg/m3, determine the speed at which
gas travels through the fuel line.
