With the aid of a given torque-speed characteristic (like that of Fig. 13-14), the steady-state speed is determined as that speed at which the magnitude of the motor torque equals that of the load torque.

Quantentheorie des Drehimpulses,-state operation of polyphase generators and motors, the stator and rotor currents produce rotating mmf waves of constant magnitude. Since these waves rotate at constant (synchronous) speed, they maintain a constant torque angle, and thereby a constant torque and constant power.

Transformer Connections,her cases, particularly when the two different voltages are in the same order of magnitude, that separation is not needed, and in these cases, considerable savings in both cost and operating expenses can be accomplished by using transformers in which the primary and secondary circuits are connected to each other to form an . circuit.
