1. What is Electric Motor Gearbox Torque?

Electric motor gearbox torque refers to the output torque generated by a gearbox connected to an electric motor. It represents the actual torque available at the output shaft after accounting for gear ratio and efficiency losses in the system.

2. How Does the Calculator Work?

The calculator uses the gearbox torque formula:

\[ T_{out} = T_{motor} \times Ratio \times \eta \]

Where:

\( T_{out} \) — Output torque (Nm)
\( T_{motor} \) — Motor input torque (Nm)
\( Ratio \) — Gear ratio (dimensionless)
\( \eta \) — Gearbox efficiency (dimensionless, 0-1)

Explanation: The formula calculates the actual torque output by multiplying the motor torque with the gear ratio and accounting for efficiency losses in the gearbox system.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for proper motor and gearbox selection, ensuring the system can handle the required load without failure, and optimizing energy efficiency in mechanical systems.

4. Using the Calculator

Tips: Enter motor torque in Nm, gear ratio (dimensionless), and efficiency value between 0-1. All values must be positive numbers with efficiency not exceeding 1.

5. Frequently Asked Questions (FAQ)

Q1: What is typical gearbox efficiency range?
A: Gearbox efficiency typically ranges from 0.85 to 0.98 (85-98%), depending on gear type, quality, and lubrication.

Q2: How does gear ratio affect output torque?
A: Higher gear ratios increase output torque but reduce output speed, following the principle of conservation of energy.

Q3: Why is efficiency important in torque calculation?
A: Efficiency accounts for energy losses due to friction, heat, and other factors in the gearbox, providing a realistic output torque value.

Q4: Can this calculator be used for all gear types?
A: Yes, the formula applies to spur gears, helical gears, planetary gears, and other gear types, though efficiency values may vary.

Q5: How accurate is this calculation for real-world applications?
A: The calculation provides a good estimate, but actual performance may vary due to factors like temperature, lubrication quality, and manufacturing tolerances.
