A DC motor has the following specifications: 10 hp, 37.5 A, 230V; flux...
The given specifications for the DC motor are as follows:
- Power (P): 10 hp
- Current (I): 37.5 A
- Voltage (V): 230V
Additionally, the motor has the following characteristics:
- Flux per pole (ϕ/pole): 0.01 Wb
- Number of poles (p): 4
- Number of conductors (Nc): 666
- Number of parallel paths (Z): 2
- Armature resistance (Ra): 0.267 Ω
Let's calculate some additional parameters based on the given information.
1. Power in Watts (Pw):
We need to convert the given power from horsepower (hp) to watts (W).
1 hp = 746 W
Pw = 10 hp * 746 W/hp = 7460 W
2. Torque (T):
The torque can be calculated using the formula:
T = (Pw * 60) / (2 * π * N)
Where N is the speed in RPM.
Since the RPM is not given, we cannot calculate the torque without this information.
3. Back EMF (Eb):
The back EMF can be calculated using the formula:
Eb = V - (I * Ra)
Where V is the voltage and I is the current.
Eb = 230V - (37.5 A * 0.267 Ω) = 230V - 10.0125 V = 219.9875 V
4. Speed (N):
The speed can be calculated using the formula:
Eb = (ϕ * N * Z) / (60 * p)
Where ϕ is the flux per pole, N is the speed in RPM, Z is the number of parallel paths, and p is the number of poles.
Rearranging the formula, we get:
N = (Eb * 60 * p) / (ϕ * Z)
N = (219.9875V * 60 * 4) / (0.01 Wb * 2)
N = 131992.5 RPM
Please note that the torque and speed calculations require the speed in RPM, which was not provided in the given specifications. If you have the RPM value, you can substitute it into the torque and speed formulas to calculate those parameters as well.
- Power (P): 10 hp
- Current (I): 37.5 A
- Voltage (V): 230V
Additionally, the motor has the following characteristics:
- Flux per pole (ϕ/pole): 0.01 Wb
- Number of poles (p): 4
- Number of conductors (Nc): 666
- Number of parallel paths (Z): 2

We need to convert the given power from horsepower (hp) to watts (W).
1 hp = 746 W
Pw = 10 hp * 746 W/hp = 7460 W

The torque can be calculated using the formula:
T = (Pw * 60) / (2 * π * N)
Where N is the speed in RPM.
Since the RPM is not given, we cannot calculate the torque without this information.
3. Back EMF (Eb):
The back EMF can be calculated using the formula:
Eb = V - (I * Ra)
Where V is the voltage and I is the current.
Eb = 230V - (37.5 A * 0.267 Ω) = 230V - 10.0125 V = 219.9875 V
4. Speed (N):
The speed can be calculated using the formula:
Eb = (ϕ * N * Z) / (60 * p)
Where ϕ is the flux per pole, N is the speed in RPM, Z is the number of parallel paths, and p is the number of poles.
Rearranging the formula, we get:
N = (Eb * 60 * p) / (ϕ * Z)
N = (219.9875V * 60 * 4) / (0.01 Wb * 2)
N = 131992.5 RPM
Please note that the torque and speed calculations require the speed in RPM, which was not provided in the given specifications. If you have the RPM value, you can substitute it into the torque and speed formulas to calculate those parameters as well.
