What is difference between stepper/brush/brushless motors? remember this list

When designing equipment that uses electric motors, it is of course necessary to choose motor that is best suited for job required.

This article compares features, performance and characteristics of brushed, stepper and brushless motors and we hope it will be a reference for everyone when choosing a motor.

However, please use it as a reference only as there are different specifications within same category of motors. At end, it is necessary to confirm detailed information in technical specifications of each motor.

Small engine specifications

The table below shows characteristics of stepper motors, brushed motors and brushless motors.

Small engine performance comparison

Comparison of performance of various small motors is shown in table.

Torque-velocity characteristics of small motors

See below for speed and torque specifications for each small motor. It can be considered that brushless motors and brushed motors are basically same.

Overview

1) When selecting motors such as brushed motors, stepper motors and brushless motors, characteristics, performance and performance comparison results of small motors can be used as a reference for motor selection.

2) When choosing motors such as brushed motors, stepper motors and brushless motors, same category of motors includes many specifications, so characteristics, performance and performance comparison results of small motors are for reference only.

3) When selecting motors such as brushed motors, stepper motors and brushless motors, it is still necessary to confirm detailed information in specifications of each motor.
