Sir,what is the advantage of three phase over single phase motor? Why many electrician say that three phase is cheaper to generate equal power then single phase?
3 phase machines are economical , compact and technically better than single phase for the same power. As you have intrest in motor, You can watch my video on Why AC motor is used in the train Engine nowadays.
Sir,please let me know if I have only single phase connection and my machine operating duration is 4 to 5 hours a day, and I have a 2hp motor required for one of my paste mixture machine,, So ,what's your advice to go for single phase motor or avail a 3 phase power supply and get a 3phase motor? My other doubt is about armature burning,,,so if I go for a 3 hp single phase motor,,will it consume more power and give a break free service?
@Tejinderbir Singh thank you very much for guidance,mujhe ek chhoti si battery factory me 3 ya 4 machine chalani thi,bahut se log 3phase suggest karte the par bina baat 3 phase connection ka kharcha kyo karu yahi me soch raha tha,,mera total loaf 10 hp se jyada nahi aayega aisa mujhe bhi lagta hai, Thanks again
@Tejinderbir Singh जी भाई जी,,एकदम सही कह रहे है आप,,बड़ी मोटर लगाने से ज्यादा बिजली खर्च होगी,पर मोटर नही जलेगी,,जैसे एक बड़ी कार में 4 लोग बहुत लंबी दूरी तय करने पर भी गर्म नही होती,पर पेट्रोल ज्यादा खाती है, पर छोटी कार गर्म हो जाती है और टूट फूट भी शुरू हो जाती है
Sir frequency matter nhi krti hai kya voltage pe, jaise ki 3 phase me 3no ko bich me 120 degree ka difference hota hai so 2 phase at a time positive me hote hai our 1 negative direction me

Namaskar sir. Aap aik video vfd ke uper bnaye the. Usme aap bta rhe the ki kisi motor ki speed frequency bdha kr kiya ja saktA. TO sir kisi motor ki kitni frequency bdha kr kitna high speed liya ja sakta hai. Agar aap is subject pe koi video bnate hai ya phir reply karege to mai aapka aabhari rahunga thank you sir
Bhai n=120f/p, n motor ki rpm,f voltage ki applied frequency,aur p no. Of poles,ab speed kitni badha sakte ho,ye depend karta hai ki motor ki rpm kitni hai,aur vfd SE motor ki speed sirf badhaya hi nhi ghataya bhi jaata hai, frequency ko Kam karke,
Mujhe pta hai ki india me 50 to 60 frequency milta hai lekin vfd ka use karke use ghataya ya badhaya bhi ja sakta hai. Bus mai ye janna chata tha ki agar kisi motor ki frequency 50 t0 60 hai to uske baad ise kitna bdhaya ja sakta hai. Ye baat vfd ke manual settings me sayad mil jayega. Lekin mai vfd kharidne se pahle janna chahta tha. Waise reply ke liye thank you.
