The Anatomy of a Brush Motor
To better understand how one works, let’s start by tearing down a simple hobby motor. As you can see, they are simple in construction, comprising of a few key components.

Disected Motor!

Brushes – Delivers power from the contacts to the armature through the commutator
Contacts – Brings power from the controller to the brushes
Commutator – Delivers power to the appropriate set of windings as the armature rotates
Windings – Converts electricity to a magnetic field that drives the axle
Axle – Transfers the mechanical power of the motor to the user application
Magnets – Provide a magnetic field for the windings to attract and repel
Bushing – Minimizes friction for the axle
Can – Provides a mechanical casing for the motor

In a brushless motor, back Sintered Neodymium Motor Magnet N30H is used to measure velocity. A stepper relies on the short throw of each winding to “guarantee” it reaches the desired point in time. In highspeed travel, this can lead to stalling where the rotor can’t keep up with the sequence. There are ways around this, but they rely on a higher understanding of the relationship between motor windings and inductance.
