A 4- pole, 158 A DC shunt generator has 300 conductors and is wave wo...
Demagnetizing and Cross-magnetizing Ampere-turns per pole in a DC shunt generator at full load can be calculated using the given data.
Given:
- Number of poles (P) = 4
- Armature current (Ia) = 158 A
- Number of armature conductors (Z) = 300
- Field current (If) = 2 A
- Brush shift (mechanical) = 50
1. Calculation of Total Ampere-turns per pole (ATp):
- Total ATp = Z * Ia
= 300 * 158
= 47400 AT
2. Calculation of Demagnetizing Ampere-turns per pole (ATd):
- ATd = 0.5 * Total ATp
= 0.5 * 47400
= 23700 AT
3. Calculation of Cross-magnetizing Ampere-turns per pole (ATc):
- ATc = If * (Z / 2 - brush shift)
= 2 * (300 / 2 - 50)
= 2 * (150 - 50)
= 2 * 100
= 200 AT
Therefore, the demagnetizing and cross-magnetizing ampere-turns per pole at full load are 23700 AT and 200 AT, respectively.
The correct answer is option 'D' (333.33 ATs/pole and 2666.67 ATs/pole), which is not the same as the calculated values. There may be an error in the given options or a mistake in the calculation.
Given:
- Number of poles (P) = 4
- Armature current (Ia) = 158 A
- Number of armature conductors (Z) = 300
- Field current (If) = 2 A
- Brush shift (mechanical) = 50
1. Calculation of Total Ampere-turns per pole (ATp):
- Total ATp = Z * Ia
= 300 * 158
= 47400 AT
2. Calculation of Demagnetizing Ampere-turns per pole (ATd):
- ATd = 0.5 * Total ATp
= 0.5 * 47400
= 23700 AT
3. Calculation of Cross-magnetizing Ampere-turns per pole (ATc):
- ATc = If * (Z / 2 - brush shift)
= 2 * (300 / 2 - 50)
= 2 * (150 - 50)
= 2 * 100
= 200 AT
Therefore, the demagnetizing and cross-magnetizing ampere-turns per pole at full load are 23700 AT and 200 AT, respectively.
The correct answer is option 'D' (333.33 ATs/pole and 2666.67 ATs/pole), which is not the same as the calculated values. There may be an error in the given options or a mistake in the calculation.
