Electric Motors and Drives: Fundamentals, Types and ApplicationsElectric Motors and Drives is intended for non-specialist users of electric motors and drives, filling the gap between theory-based academic textbooks and the more prosaic 'handbooks', which provide useful detail but little opportunity for the development of real insight and understanding. The book explores all of the widely-used modern types of motor and drive, including conventional and brushless D.C., induction motors and servo drives, providing readers with the knowledge to select the right technology for a given job. Austin Hughes' approach, using a minimum of maths, has established Electric Motors and Drives as a leading guide for engineers, and the key to a complex subject for a wider readership, including technicians, managers and students. * Acquire essential practical knowledge of motors and drives, with a minimum of math and theory * Updated material on the latest and most widely-used modern motors and drives * New edition includes additional diagrams and worked examples throughout |

User Review - John_Hardy - LibraryThingThis book is brilliant. It isn't stylish, it's not lavishly illustrated, it isn't even a riveting read. It is, however, plain old fashioned lucid. Hughes is or was an academic, and if he lectured as ... Read full review

Page 122 - When plugging, ie, throwing from full speed in one direction to full speed in the other, it is desired to have a time delay in the closing of contactor 2ft.
Page 3 - H _ £V1_ = ,£W I 0.4 10. FORCE ON A CURRENT-CARRYING CONDUCTOR LYING IN A MAGNETIC FIELD It has been found that whenever a current-carrying conductor is placed in a magnetic field, it experiences a force which acts in a direction perpendicular both to the direction of the current and the field. — Fig. 12 (a) shows the field set up by the poles. — Fig. 12 (b) shows the conductor field due to flow of current in the conductor.
Page 233 - ... temperature drift observed in the other methods. Again, since the method measures directly temperature changes it is completely independent of the physical properties of the reactants. It could also be used for continuously following the course of a reaction, by measuring the equilibrium temperature attained when the rate of loss of heat to the surroundings is equal to the rate of heating produced by the chemical reaction, provided the half -life of heat in the system does not change during the...
Page 6 - This is a delightfully simple formula, and it may come as a surprise to some readers that there are no constants of proportionality involved in equation 1 .2.
Page 183 - This speed is directly proportional to the frequency of the supply, and inversely proportional to the number of poles on the motor.
Page 379 - C. above the surrounding air. What would be the \-hour rating of the motor for this temperature rise, assuming that it cools down completely between each load period and that the losses are proportional to the square of the load...
Page 342 - The synchronous machine with permanent magnets on the rotor is the heart of the modern brushless servomotor. The synchronous motor stays in synchronism with the supply, although there is a limit to the maximum torque which can be developed before the rotor is forced out of synchronism. Pull-out torque will be typically between one and a half and four times the continuously-rated torque. The torque speed curve is therefore simply a vertical line, which indicates that if we try to force the machine...
Page 183 - ... is proportional to the applied voltage and inversely proportional to the frequency.
