Question

100 kilowatt belt during DC shunt generator running on full load at 300 RPM and 220 volt bus by continuous to run ​

Answer 1

• -- ᴀɴɪᴍᴇᴘᴜɴᴋ --

A belt-driven 100-KW, shunt generator running at 300 r.p.m. on 220-V bus- bars continues to run as a motor when the belt breaks, then taking 10 KW.

                                                       -

What will be its speed? Given armature resistance = 0.025 W, field resistance = 60 W and contact drop under each brush.

• Hope this helps!
