Current (approx):


I = \frac{60 \times 1000}{\sqrt{3} \times 415} \approx 83.5 \text{ A}

2. Basic Design Parameters

Phase: 3 Phase

Connection: Star (Y)

RPM: 1500 (for 4-pole at 50 Hz)

Poles: 4

⚙️ Armature Winding Specifications (Approximate)

Parameter Value

Slots 72 (common for 4-pole design)
Poles 4
Slots per pole per phase (SPP)
Coil pitch 1 to 13 slots (short-pitched, ~11 commonly used)
Winding type Double Layer, Lap or Wave
Conductor per slot 8 to 12 (based on current capacity and wire size)
Conductor size ~SWG 15 or 16 (or ~1.4 mm to 1.6 mm diameter) – needs calculation as per insulation class & temperature rise
Turns per coil 6 to 15 (depends on voltage and EMF per turn)

📐 Important Design Notes:

1. Winding Type: Generally double-layer, lap winding is used in alternators up to 100 kVA.


2. Conductor Material: Super enamelled copper wire.


3. Insulation Class: Class F or Class H.


4. Coil Pitch: Short-pitched winding reduces harmonics (commonly 1 or 2 slots short).


5. Cooling: Ventilation ducts between slots may be required.


6. Winding connection: Star connection is typical for 415 V output.


7. Phase Sequence: R – Y – B (clockwise)
