Where:

*P*= Power (in horsepower)*T*= Torque (in pound-feet)*ω*= Angular speed (in revolutions per minute)*η*= Efficiency (in decimal)

**Example Solve:**

Let’s say we have a system with a torque of 200 pound-feet, an angular speed of 300 revolutions per minute, and an efficiency of 0.85. Plugging these values into the formula:

**FAQs:**

**Q: What units should I use for torque and angular speed?**

A: Torque should be in pound-feet, and angular speed should be in revolutions per minute (RPM).

**Q: Why is efficiency important in motor power calculations?**

A: Efficiency accounts for losses in the motor system, providing a more accurate representation of the power required.

**Q: Can this calculator be used for both AC and DC motors?**

A: Yes, the calculator works for both AC and DC motors as long as the input parameters are correct.

**Conclusion:**
