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…
Speed Torque Characteristic DC Shunt Motor: The preceding discussion shows that armature voltage variation gives creeping speeds. The simple rheostatic method provides a Speed Torque Characteristic DC Shunt Motor with…
Field Control Method of DC Shunt Motor: The Field Control Method of DC Shunt Motor are in general much more adaptable speed drives than ac motors which are associated with…
Speed Control of Three Phase Induction Motor: The problem of speed control of three phase induction motor in particular is of great practical importance. In a number of industries motors…
Armature Resistance Control Method of DC Motor: In this armature resistance control method of speed control, reduced speeds are obtained by inserting resistance in the armature circuit. It may be…
Paralleling Field Coils for DC Series Motor: In this Paralleling Field Coils method, used in fan motors, several speeds can be obtained by regrouping of field coils, as illustrated in…
Field Diverter Method of Speed Control of DC Series Motors: The field flux can be reduced by shunting a portion of motor current around the series field, thus reducing the…
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…
