Product Code : SCL-EELE-13030
Indian Lab Suppliers supplies the 300 W / 220 V / 1500 RPM / Non Interpolar DC Series Generator Frame : 90 (Product ID: 13030) as part of its electronics engineering lab equipment range. It is a 300 W non-interpolar DC series generator for studying the rising load characteristic.
Quick Answer
The field winding carries the full load current, so at 1500 RPM the terminal voltage is close to zero on open circuit and rises with load current, towards its 220 V rating, until the iron saturates. Students plot this external characteristic with a variable resistive load and compare it with a shunt generator. Voltage build-up needs residual magnetism and a closed load circuit. It is built in frame 90 with an SPDP (IP23) enclosure and Class B insulation, and must be driven by a separate prime mover with the coupling guarded.

Frequently Asked Questions
Why is there almost no voltage on open circuit?
With no load current the series field carries no current, so only residual flux remains.
What does the load test show?
Terminal voltage rising with load current until saturation.
What is its rating?
300 W, 220 V, 1500 RPM.
