Features of Electric Drive System: Before applying advantageously the control principles to electric drive systems to adjust or improve their behaviour as a special case of control problem, it is…
Reversible Drive using Field Reversal: A Reversible Drive using Field Reversal can be realised as shown in Figs. 4.83 and 4.84. In Fig. 4.83, the armature is fed from a…
Methods to Leading Power Factor: We have seen that a phase controlled converter requires reactive power for control and commutation. The harmonics do not contribute to the active power loading…
Single Phase Separately Excited DC Motor Drives: The circuit arrangement of a Single Phase Separately Excited DC Motor Drives Drives fed from a single phase controlled converter is shown in…
Commutation in DC Motor: Commutation and commutator wear and tear of the dc motor must be given due consideration when the motor operates on solid state converters. Spark-less commutation must…
Torque Equation of DC Motor: When dc voltage is applied to the armature of a dc motor with its field excited by dc, a torque is developed and the armature…
Starting Methods of Synchronous Motor for LCI: It has been pointed out that a Starting Methods of Synchronous Motor for LCI, even though complicated in its construction, has an advantage…
Voltage Source Inverter Fed Synchronous Motor Drive: An inverter fed synchronous motor has been very popular as a converter motor in which the synchronous motor is fed from a CSI…
