    During run-up as an induction motor, the torque produced by a synchronous machine has oscillating components in addition to the natural frequencies of torsional oscillation of the complete drive system so that the shaft torque may differ substantially from the motor electromagnetic torque. The latter can be divided into four components: 1) a unidirectional or accelerating component, 2) an oscillat... View full abstract»

    The temperature of motor surfaces is still a major concern of those operating equipment in hazardous (classified) areas. This surface temperature must be below the ignition temperature of the atmosphere under all possible operating conditions for Division 1 environments. Currently a 2150C maximum surface temperature is a must for a motor that can be operated in any Class I, Group D, Divisio... View full abstract»

    Every motor user is faced with the fact that someday his motor will fail. Due to the destructive nature of most failures, it is not easy to determine the cause. The purpose of this paper is to introduce a procedure for analyzing these failures and determining the cause so that further steps can be taken to eliminate them. View full abstract»

    A dc motor is modeled by means of a network representation of an analogous mechanical system consisting of a velocity source, rotational damper, and rotational spring which derive from the no-load speed, armature resistance, and armature inductance, respectively. It is shown that the reduction in the field due to the cross-magnetization effect of the armature current can be approximated by an addi... View full abstract»

  • Industrial Turbine Energy Supply Systems - An Economic Way to Save Energy

    Publication Year: 1978, Page(s):234 - 241
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2954 KB)

    Turbines, integrated into the process plant's need for both process heat and power, can generate power (kW and/or hp) with less than half the fuel required by a separate plant generating and transmitting electric power to the industrial. In those processes where there is a source of waste heat, there may be potential for economic conversion of this heat into turbine power. Typical examples will sh... View full abstract»

    Since the onset of energy crunch, turning off lights has become the symbol of energy savings. The results are far from being satisfactory, in some cases, even counter productive. The most important contribution which a lighting engineer can make as far as energy saving is concerned will be to apply his technical know-how to provide adequate but economic lighting, especially in the industrial plant...

    Electrical restricted breathing material is material which can be used for practice in explosion-endangered areas under certain conditions. It can be used in cases where the occurrence of explosive gas-air or vapor-air mixtures is safely limited to a short time. In such cases with a time-limited danger of explosion, the demand for using completely explosion-proof material is not always economicall... View full abstract»

    Electrical equipment for a cement plant should be placed in rooms for protection of the equipment itself and to avoid unauthorized persons from coming in contact with the equipment. Electrical equipment generates heat, and this heat must be dissipated in order to maintain the ambient temperature within the proper limits. There is also a possibility of electrical fires due to faults in the electric... View full abstract»
