Voltage, Current and Power in 3 Phase Star Connection: 3 Phase Star Connection - Figure 9.21 shows a balanced three-phase, Y-connected system. The voltage induced in each winding is called…
Difference Between Star and Delta Connections: Difference Between Star and Delta Connections - In star connection with earthed neutral, the maximum voltage of the phase winding to ground is 1/√3…
Star Delta Starter Working Principle and Circuit Diagram: This star delta starter method of starting of cage induction motors is based upon the principle that with 3 windings connected in star,…
Counter Emf Automatic Starter - Working Principle and its Drawbacks: This type of starter depends upon the build up of the back or counter emf to operate the contactors (a…
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…
Capacitor-Start Capacitor-Run Single Phase Induction Motor: The capacitor-start capacitor-run motor is similar to capacitor-start, induction-run motor, except that the auxiliary winding and a capacitor remain connected in the circuit at…
Resistance Start Single Phase Induction Motor: It is a form of split-phase motor having a high resistance connected in series with the auxiliary or starting winding, as illustrated in Fig.…
