1. What is Motor Output Power?

Definition: This calculator converts mechanical horsepower to electrical power output in watts.

Purpose: It helps engineers and technicians determine the electrical power equivalent of mechanical horsepower ratings.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_w \) — Power output in watts
• \( HP \) — Horsepower rating

Explanation: One mechanical horsepower is equivalent to 746 watts of electrical power.

3. Importance of Power Conversion

Details: Accurate power conversion ensures proper motor sizing, electrical system design, and energy efficiency calculations.

4. Using the Calculator

Tips: Enter the horsepower rating (HP) to get the equivalent power in watts. Value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 746 watts per horsepower?
A: This is the standard conversion factor based on James Watt's original definition of horsepower.

Q2: Does this work for metric horsepower?
A: No, metric horsepower (PS) uses 735.5 watts. This calculator is for mechanical horsepower.

Q3: Is this the actual power consumption?
A: No, this is theoretical output power. Actual consumption depends on motor efficiency.

Q4: Can I use this for generators too?
A: Yes, the same conversion applies when rating generator output power.

Q5: How precise is this conversion?
A: The 746 watts/hp is a standardized value, though actual values may vary slightly.
