    The current and increasing use of computers to produce train performance calculator (TPC) studies for new intercity passenger, freight, and transit systems or changes to existing ones results in large quantities of output data. The more data there are, the more complex they are to understand. A visual representation of TPC outputs is described which greatly simplifies the understanding of the comp... View full abstract»

    Since the National Electric Code has dropped rules for capacitors at motors, the electrical engineer's responsibility has been established. Nevertheless, the Code's 1981 edition suggests a simplified rational method of selecting capacitor size that is discussed here. The electrical engineer is assumed to understand that the purpose of applying capacitors is not merely to take care of an individual... View full abstract»

    The stresses are discussed to which the riding rings of rotary kilns are subjected. These stresses are caused partly by forces acting on the rings and partly by thermal gradients. By nature the stresses are static and dynamic. Particular attention is paid to the Hertzian pressure which must be regarded as the most significant load factor because, apart from surface stresses, other stresses are pro... View full abstract»

    The usual uncoupled d - q model of salient pole synchronous machines (Park's model) may be insufficient for accurate modeling of buried magnet permanent magnet machines. The addition of a nonbilateral coupling between the direct and quadrature axis equivalent circuits is shown to improve the steady-state model greatly. The cross coupling reactance has important implications in improving operation ... View full abstract»

    One of the limitations of conventional autosequentially commutated inverter (ASCI) for high-power induction motor drives is the high voltage that is produced in the commutation capacitors during the current commutation from one phase to another. Since the capacitor voltage appears directly on the semiconductor components, it increases their required voltage ratings. Also, the high-voltage spikes g... View full abstract»
