Technical Reference: Motor Parameters Application Note

From Parker Hannifin/Electromechanical Automation

Linear motor parameters can be confusing and difficult to understand, especially when different manufacturers use different methods to formulate and present them. This application note will start with first principles and establish motor parameter formulations that are consistent and convenient to measure.

Brushless Motors
Brushless motors are synchronous electric motors that have a magnetically (AC induction) or electronically (DC) controlled commutation system instead of a brush-based mechanical commutation system.
DC Servomotors
DC servomotors are generally small and powerful for their size, and easy to control. Common types of DC servomotors include brushless or gear motors.
DC Motors
DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors.
Gearmotors
Gearmotors consist of an AC or DC motor with an integral gearbox or gear head typically used to adjust the motor's output speed and torque.
Stepper Motors (Rotary)
Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps. They provide precise positioning and ease of use, especially in low acceleration or static load applications.
