1. What is a 10 kW Electric Motor?

A 10 kW (kilowatt) electric motor is a medium-power motor commonly used in industrial applications, pumps, compressors, and other machinery. It converts electrical energy into mechanical energy with a power output of 10,000 watts.

2. How Does the Calculator Work?

The calculator uses electrical power formulas:

For single phase: \[ I = \frac{P}{V \times PF \times \eta} \]
For three phase: \[ I = \frac{P}{\sqrt{3} \times V \times PF \times \eta} \]

Where:

\( I \) — Current (Amperes)
\( P \) — Power (10,000 Watts)
\( V \) — Voltage (Volts)
\( PF \) — Power Factor (0-1)
\( \eta \) — Efficiency (0-1)

3. Importance of Motor Calculations

Details: Proper current calculation ensures correct wire sizing, circuit breaker selection, and protection device settings for safe motor operation.

4. Using the Calculator

Tips: Enter motor voltage, estimated efficiency (typically 85-95%), select phase configuration, and power factor (typically 0.8-0.95 for motors).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between single and three phase?
A: Three-phase motors are more efficient for industrial applications, while single-phase is common for smaller applications.

Q2: How does efficiency affect current?
A: Lower efficiency means more current is needed to produce the same power output.

Q3: What's a typical power factor for motors?
A: Usually between 0.8-0.95, with higher values for larger, more efficient motors.

Q4: Can this calculator be used for other motor sizes?
A: The formulas apply to any motor, but this calculator is specifically for 10 kW motors.

Q5: Why is current calculation important?
A: It determines wire size, overload protection, and starter selection for safe operation.
