Show Your Love:

The Brushless Motor Torque Calculator is a tool designed to unravel the mysteries of brushless motors by determining their torque. Torque, measured in Newton-meters (Nm), is a crucial factor in understanding the performance of these motors. The calculator employs a straightforward formula:

Torque (Nm) = k * I * φ

Where:

  • Torque: The rotational force exerted by the brushless motor (Nm).
  • k: A constant dependent on the motor design, extracted from motor specifications.
  • I: The current flowing through the motor windings in amperes (A).
  • φ: The magnetic flux produced by the motor in Weber (Wb).

Example of Brushless Motor Torque Calculator

Let’s illustrate the calculator’s functionality with an example:

Suppose we have a brushless motor with a constant (k) of 0.5, a current (I) of 10 amperes, and a magnetic flux (φ) of 8 Weber. Applying the formula:

Torque = 0.5 × 10 × 8 = 40Nm

Hence, the torque of the brushless motor in this scenario is 40 Newton-meters.

Most Common FAQs

Q: Is the torque value obtained from the calculator accurate for all brushless motors?

A: No, the accuracy depends on the precision of the input values and the correctness of the constant (k) obtained from motor specifications.

Q: Can I use the calculator for any brushless motor, regardless of its size?

A: Yes, as long as you have the necessary information, such as the constant (k), current (I), and magnetic flux (φ).
