Types of DC Motors

So far, this guide has broadly explained how DC motors work, the history of these mechanisms, and what they look like. While the principles are the same across variants, there are actually several different types of DC motors, which offer specific advantages and disadvantages over each other.

This section of the guide will look at the four main types of DC motor - brushless, brushed, shunt, and series.

▍Brushless DC motor

Due to the development of solid-state electronic technology, a brushless DC motor is also called an electronic commutation motor or synchronous DC motor, which is different from a brush motor.
The key difference between brushless DC motors and other types of motors is that they have no commutator, which is replaced by an electronic servo mechanism that can detect and adjust the rotor angle.
A Brushless DC motor has several advantages. The commutator uses soft contacts called "brushes", which will wear out over time. Therefore, a brushless DC motor is more durable and safer than the more classic design.

How does a brushless DC motor work?

All motors generate torque by alternating the polarity of rotating magnets connected to the rotor and fixed magnets on the surrounding stator. At least one of the magnets in this group is an electromagnet, which is made of coils around the iron core.
In a DC motor, the DC current flowing through the wire winding generates a magnetic field. Each time the armature rotates 180 °, the positions of the north and south poles are reversed. If the magnetic field of the magnetic pole remains unchanged, the rotor will not rotate. In order to generate torque in one direction of the DC motor, the direction of current must be reversed for every 180 ° rotation of the armature.
In the traditional brush motor, this will be done by the commutator, but in the brushless DC motor, the electronic sensor detects the angle of the rotor and controls the semiconductor switch to either reverse the current direction or turn off the current at the correct time of rotation, so as to generate torque in one direction.

▍Brushed DC motors

The Brush DC motor is the original DC motor, which can be traced back to the original design of Sprague. As we have discussed in this guide, the classic brush motor has a commutator that reverses the current and generates unidirectional torque every half cycle.
Although brushless DC motors are still popular in electric propulsion, cranes, paper machines, and rolling mills, in recent years, many brushless motors have been eliminated due to more efficient brushless models.

How does a brushed DC motor work?

As has been explained in this guide already, brushed DC motors utilize soft contacts known as ‘brushes’ to ensure the motor rotates in one direction. Brushed motors’ speed can be varied by the operating voltage or the strength of the magnetic field.
There are a few different varieties of brushed DC motors, which differ depending on the connection to the armature, which will be discussed in the following sections.
