1. What is Energy Consumption Calculation?

The energy consumption calculation determines how much electrical energy a motor uses over a period of time. For a 15 kW motor, this helps estimate operating costs and efficiency.

2. How Does the Calculator Work?

The calculator uses the basic energy formula:

Where:

• \( E \) — Energy consumption (kWh)
• \( P \) — Power of the motor (15 kW fixed in this case)
• \( t \) — Operation time in hours

Explanation: The formula simply multiplies the motor's power rating by the number of hours it operates to determine total energy used.

3. Importance of Energy Calculation

Details: Calculating energy consumption helps in estimating electricity costs, assessing motor efficiency, and planning energy usage in industrial or commercial settings.

4. Using the Calculator

Tips: Enter the total operation time in hours. The calculator assumes continuous operation at full 15 kW load. For variable loads, more complex calculations are needed.

5. Frequently Asked Questions (FAQ)

Q1: What if my motor doesn't run at full load?
A: This calculator assumes full load. For partial loads, multiply the result by the load factor (e.g., 0.8 for 80% load).

Q2: How can I calculate the cost from this result?
A: Multiply the kWh result by your electricity rate (per kWh) to get the operating cost.

Q3: Does this account for motor efficiency?
A: No, this is the electrical input energy. Output mechanical energy would be less due to efficiency losses.

Q4: Can I use this for motors with different power ratings?
A: This calculator is specifically for 15 kW motors. For other ratings, you'd need to adjust the power value.

Q5: What's the typical energy consumption for a 15 kW motor?
A: At full load, it consumes 15 kWh per hour of operation. For 8 hours/day, that's 120 kWh daily.
