Motor Newton Meter Formula:
| From: | To: |
The Motor Newton Meter Calculation determines the torque produced by a motor using the relationship between power and angular velocity. Torque is a crucial parameter in mechanical systems that describes the rotational force applied by the motor.
The calculator uses the torque formula:
Where:
Explanation: This formula shows that torque is directly proportional to power and inversely proportional to angular velocity. Higher power or lower angular velocity results in greater torque output.
Details: Accurate torque calculation is essential for motor selection, mechanical design, performance analysis, and ensuring proper operation of rotational systems. It helps determine if a motor can provide sufficient rotational force for a specific application.
Tips: Enter power in watts and angular velocity in radians per second. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the difference between torque and power?
A: Torque is the rotational force, while power is the rate at which work is done. Power equals torque multiplied by angular velocity.
Q2: How do I convert RPM to rad/s?
A: Multiply RPM by 2π/60. For example, 1000 RPM = 1000 × (2 × 3.1416) / 60 ≈ 104.72 rad/s.
Q3: What are typical torque values for electric motors?
A: Torque values vary widely depending on motor size and type, ranging from fractional Nm for small motors to thousands of Nm for large industrial motors.
Q4: Can this formula be used for all types of motors?
A: Yes, this fundamental relationship applies to all rotational motors, though efficiency factors may need consideration for precise calculations.
Q5: Why is torque measured in Newton meters?
A: Newton meter is the SI unit for torque, representing the force of one Newton applied perpendicularly at a distance of one meter from the pivot point.
