Please note — cover year vs approval: BTEUP's own file for this curriculum prints "YEAR 2025-2026" on its cover, while carrying the approval line "UPDATED AND APPROVED BY BOARD OF TECHNICAL EDUCATION U.P. LUCKNOW IN C.D.C MEETING HELD ON 16.07.2026" on every page. It is filed in BTEUP's 2026-27 folder (folder2627), so it is treated here as the 2026-27 syllabus on the strength of that approval. The scheme it carries is identical, subject for subject and mark for mark, to the 2025-26 scheme.
Electric Machine-2 (Lab) — What This Subject Is About
This is the lab for the theory paper 4.2 (Electric Machine- II). Here you run the AC machines themselves: starting and running three-phase induction motors with DOL, star-delta and auto-transformer starters, load tests and V-curves of synchronous motors, synchronising alternators by the lamp and synchroscope methods, and controlling stepper and servo motors. The PDF lists 15 practicals and says to perform any ten.
There are no theory units and no reference books listed for this subject — it is a practical subject (L 0 – P 4), worth 100 marks and 2 credits. The complete list of 15 practicals is in the Complete Syllabus section below and in the PDF.
Subject 4.6 (Practical) • Total 100 Marks • 2 Credits • L 0 – P 4 • Perform any 10 of 15 practicals • 4th Semester — Electrical Engineering • Session 2026–27

Complete Practicals List
This is the complete list of practicals from the official syllabus.
- Identify the different parts (along with function and materials) for the given single phase and three phase induction motor.
- Connect and run the three-phase squirrel cage induction motors (in both directions) using the DOL, star-delta, auto-transformer starters (any two).
- Perform the direct load test on the three-phase squirrel cage induction motor and plot the (a) efficiency versus output, (b) power factor versus output, (c) power factor versus motor current and (d) torque – slip/speed characteristics.
- Conduct the No-load and Blocked-rotor tests on given 3-phase squirrel cage induction motor and determine the equivalent circuit parameters.
- Control the speed of the given three phase squirrel cage/slip ring induction motor using the applicable methods: (a) auto-transformer, (b) VVVF.
- Measure the open circuit voltage ratio of the three-phase slip ring induction motor.
