Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFLap and wave winding:
|
Lap winding |
Wave winding |
|
No. of parallel paths is equal to no. of poles |
No. of parallel paths is always equal to 2 |
|
Used for high current and low voltage machines |
Used for low current and high voltage machines |
|
Efficiency is lower |
Efficiency is higher |
|
No. of brushes is equal to no. of poles |
No. of brushes is equal to 2 |
Hence, statement 1 is false and statement 2 is true.
