DC Shunt Generators:
A DC shunt generator is a type of direct current (DC) generator that operates with a shunt field winding connected in parallel with the armature winding. It generates a steady output voltage by regulating the field current.
Given Information:
- Voltage generated at 1800rpm: 400V
- Speed of the generator to generate the desired voltage: 20rps
Calculating Flux Increase:
To determine the percentage increase in flux per pole required to generate 500V at 20rps, we can use the formula:
V1 / V2 = (N1 / N2) * (Φ1 / Φ2)
Where:
- V1 is the initial voltage (400V)
- V2 is the desired voltage (500V)
- N1 is the initial speed (1800rpm)
- N2 is the desired speed (20rps)
- Φ1 is the initial flux per pole
- Φ2 is the desired flux per pole (to be calculated)
Calculating Speed Conversion:
First, we need to convert the speed from rpm to rps:
N1 = 1800rpm * (1/60) = 30rps
Calculating Flux Increase:
Next, we rearrange the formula and solve for Φ2:
Φ2 = Φ1 * (N1 / N2) * (V2 / V1)
Substituting the given values:
Φ2 = Φ1 * (30rps / 20rps) * (500V / 400V)
Simplifying the equation:
Φ2 = Φ1 * 1.5 * 1.25
Φ2 = Φ1 * 1.875
Therefore, the flux per pole needs to increase by 1.875 times or 87.5% in order to generate 500V at 20rps.
In summary, to generate 500V at 20rps, the flux per pole needs to increase by 87.5% compared to the flux generated at 1800rpm. This can be achieved by increasing the field current or adjusting the field winding configuration.
