Continuous Duty Motor: There are two types of Continuous Duty Motor — continuous duty at constant load and continuous duty with variable load cycle. In the former the load torque remains…
Single Phase DC Series Motor Drives: In the Single Phase DC Series Motor Drives the field is connected in series with the armature. The field current is the same as…
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…
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…
Three Phase AC Voltage Controller: To control the current and voltage of three phase loads, Three Phase AC Voltage Controller are required. The single phase controller described previously can be…
Charging a Capacitor in Inverter: Charging a Capacitor in Inverter - Inverters are static power converters for converting dc to ac. By controlling the conducting periods of the thyristors it…
Starting Method of Induction Motor: Transient processes involved with the Starting Method of Induction Motor in a variable speed drive require a detailed study. The electric motor and connected load…
