1. What is the Servo Motor Torque Formula?

The servo motor torque formula calculates the torque produced by a motor based on its power and rotational speed. It's essential for selecting the right motor for specific applications and ensuring proper performance.

2. How Does the Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque in Newton-meters (Nm)
• \( P \) — Power in kilowatts (kW)
• \( N \) — Rotational speed in revolutions per minute (RPM)
• 9550 — Conversion factor (derived from unit conversions)

Explanation: The formula shows the inverse relationship between torque and speed - as speed increases, torque decreases for a given power.

3. Importance of Torque Calculation

Details: Proper torque calculation ensures the motor can handle the required load, prevents overheating, and maintains efficiency. It's crucial for applications requiring precise motion control.

4. Using the Calculator

Tips: Enter power in kW and speed in RPM. Both values must be positive numbers. The calculator will compute the torque in Nm.

5. Frequently Asked Questions (FAQ)

Q1: Why is 9550 used in the formula?
A: 9550 is a conversion factor derived from unit conversions (kW to W, RPM to rad/s, and unit adjustments).

Q2: What's the difference between nominal and peak torque?
A: Nominal torque is the continuous torque a motor can produce, while peak torque is the maximum short-term torque capability.

Q3: How does voltage affect servo motor torque?
A: Higher voltage typically allows for higher torque output, but must stay within the motor's rated specifications.

Q4: What if my motor speed is zero?
A: The formula becomes undefined at zero speed. Servo motors produce maximum torque at zero speed (stall torque).

Q5: How does gear ratio affect torque?
A: Adding a gearbox increases output torque proportionally to the gear ratio while decreasing speed by the same ratio.
