Selection Procedure

First, determine certain features of the design, such as drive mechanism, rough dimensions, distances moved, and positive period.

Confirm the required specifications for the drive system and equipment (stop accuracy, position holding, speed range, operating voltage, resolution, durability, etc.)

Calculate the value for load torque, load inertia, speed, etc. at the motor drive shaft of the mechanism. Refer to individual calculations for speed, load torque and load inertia for various mechanisms. Click here for Motor Sizing Calculation Formulas.

Select a motor type from AC Motors & Brushless DC Motors or Stepping Motors based on the required specifications. Review considerations for Stepping Motors.

Make a final determination of the motor after confirming that the specifications of the selected motor/gearhead satisfy all of the requirements (mechanical strength, acceleration time, acceleration torque etc.)
