The top and bottom form one region, the left side forms a second region, and the right side forms a third region. Sketch the magnetization current that would flow in the transformer. The slot pitch is 2 mechanical degrees or 24 electrical degrees. As you can see, they intersect at a terminal voltage of V. Please note that fundametnals file extent of the magnetization curves and open-circuit characteristics have changed in this edition.

Answer the following questions about the machine of Problem The magnetization curve for a separately excited dc generator is shown in Figure P9—7. Find the induced torque in the motor in Fundameentals 10—5 fundamwntals it is operating at 5 percent slip and its terminal voltage is a V, b V, c V. Is it the armature current or the field current that limits the reactive power output? This increase in sidelobe frequency has two major advantages: It would be easy to modify the function to use any arbitrary dc voltage, if desired. A generating station for a power system consists of four MVA kV 0. Refer to the simple two-pole eight-coil machine shown in Figure P What is the flux density in each of the legs? Figure a shows a simple circuit consisting of a voltage source, a resistor, and two reactances.

What would happen in this circuit if switch S1 were closed? It produces an output power of 75 kW at 3. Friction, windage, and stray losses may be assumed negligible. An air-gap flux density of 0. This voltage will be the same polarity as the direction shown on the core, so it will be positive. Its armature resistance RA is 0.

The fifth harmonic would be suppressed by this winding as follows: The open-circuit characteristic of this motor is shown in Figure P Manuwl this torque-speed curve to that of the shunt motor in Problem and the cumulatively- compounded motor in Problem The motor described above is connected in shunt.

What is the phase current elrctric the motor at rated conditions? Assume that the field current of the generator in Problem has been adjusted so that it supplies rated voltage when loaded with rated current at unity power factor. A V, four-pole, hp, Hz, Y-connected three-phase induction motor develops its full-load induced torque at 3.

Assume that the lines in the system have zero impedance.

How much current is required to produce an air-gap flux density of 0. How does the new speed compare to the full-load speed calculated in Problem 9—10?

Compare the two curves. A farmer along the road has a V feeder supplying kW at 0.

The ac machine has four poles and is Y-connected. A two-legged dundamentals is shown in Figure P1—4. To understand the behavior of the inverter portion of this circuit, we will step through its operation.
