Detailed Solution
Download Solution PDFआघूर्ण समीकरण:
त्रि-प्रावस्था परिवर्तन चलित्राचे आघूर्ण समीकरण पुढीलप्रमाणे दिले जाते,
जिथे Ns ही समकालिक गती आहे
V = व्होल्टता पुरवठा
R2 = घूर्णक प्रतिरोध
X2 = घूर्णक अवरोधन
s सरक आहे
वरील समीकरणाद्वारे, आपण असे म्हणू शकतो की परिवर्तन चलित्राचा आघूर्ण घूर्णकाचा प्रतिरोध आणि प्ररोह यावर अवलंबून असतो.
कमाल आघूर्णसाठी स्थिती:
सुरवातीला जास्तीत जास्त आघूर्ण मिळण्याची स्थिती ही आहे,
Xm = Rm
जिथे,
Rm = प्रति प्रावस्था चलित्र प्रतिरोध
Xm = प्रति प्रावस्था चलित्र अवरोधन
त्रि-प्रावस्था सरक वलय परिवर्तन चलित्राच्या प्रारंभी
सरक (s) = 1 (प्रारंभी Nr = 0)
म्हणून,
⇒ Xm = Rm
म्हणून घूर्णकाचा प्रतिरोध घूर्णक अवरोधनासमान असतो तेव्हा परिवर्तन चलित्राचे प्रारंभिक आघूर्ण कमाल असते.
