Torque Equation:
| From: | To: |
The torque equation T = Kt × I calculates torque from motor current and torque constant. This fundamental relationship is essential in motor control and electromechanical systems design.
The calculator uses the torque equation:
Where:
Explanation: The equation shows the direct proportional relationship between torque and current, with the torque constant as the proportionality factor.
Details: Accurate torque calculation is crucial for motor selection, performance analysis, and ensuring proper operation of mechanical systems. It helps in determining the required power and efficiency of electromechanical devices.
Tips: Enter torque constant in Nm/A and current in Amperes. Both values must be positive numbers greater than zero for valid calculation.
Q1: What is torque constant (Kt)?
A: Torque constant is a motor parameter that relates the current flowing through the motor to the torque produced. It's typically provided in the motor specifications.
Q2: Does RPM affect torque calculation?
A: In the basic equation T = Kt × I, RPM doesn't directly affect torque calculation. However, motor characteristics may change with speed due to back EMF and other factors.
Q3: Can this equation be used for all motor types?
A: This equation is primarily used for DC motors and brushless DC motors. AC motors and other motor types may have different torque-current relationships.
Q4: What are typical torque constant values?
A: Torque constant values vary significantly depending on motor size and design, typically ranging from 0.01 Nm/A for small motors to several Nm/A for large industrial motors.
Q5: How accurate is this calculation?
A: The calculation provides theoretical torque based on ideal conditions. Actual torque may vary due to factors like temperature, magnetic saturation, and mechanical losses.
