Motor Sizing Process

The basic procedure for sizing a motor is:

  1. Determine move parameters
  2. Calculate load inertia (or mass)
  3. Calculate peak and rms torque (or force) requirements

While the steps for motor sizing remain constant, different mechanical systems require different formulas to calculate the first three steps. The selection of the motor is determined by the general characteristics of the motor desired and the ability of the motor to meet the calculated requirements.
