DC Series Motor Starter Working Principle: The series motor starter serves the same purpose as the three- and four-point starters employed with shunt and compound wound motors. However, series motor…
Thyristorised Control of DC Electric Traction Motor: The modern trend is towards the use of dc motors (both separately excited and dc series motors) equipped with thyristor chopper control. The…
Starting and Speed Control of DC Traction Motors: Starting and Speed Control of DC Traction Motors - As already discussed, only series and compound dc motors are suitable for traction…
Rectifier Control of DC Series Motor: Single-phase controlled Rectifier Control of DC Series Motor are employed in traction. A single-phase half-controlled Rectifier Control of DC Series Motor is shown in…
Dual Converter Control of DC Separately Excited Motor: A Dual Converter Control of DC Separately Excited Motor (Fig. 5.35) consists of two fully-controlled rectifiers connected in anti-parallel across the armature.…
DC Shunt Motor Starter Design: Maximum current that a DC Shunt Motor Starter Design can safely carry during starting is limited by the maximum current that can be commutated without…
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…
Control of DC Electric Motor: A separately excited DC Electric Motor is very versatile as a variable speed motor. Its speed can be varied by varying the applied voltage to…
