Introduction to BLDC Motor Winding
#

Brushless DC motors (BLDC motors) have become a cornerstone in modern electric motor technology, offering efficiency and reliability across a wide range of applications. At the heart of their production lies the precision of coil winding, a process that determines the performance and durability of the final motor.

What is a BLDC Motor?
#

A BLDC motor is an electric motor that operates without brushes and a commutator. Instead, it uses electronic control to adjust the stator current, generating torque based on the position of the rotor’s permanent magnets. Despite the name, a BLDC motor is technically a permanent magnet synchronous motor (PMSM) that utilizes three-phase electricity. The term “brushless DC motor” is used because these motors can replace traditional brushed DC motors in many scenarios. To distinguish them from mechanically commutated motors, they are also referred to as EC (electronically commutated) motors.

Types of BLDC Motors
#

BLDC motors are generally categorized into two types:

Inner Rotor BLDC Motors: The rotor is located inside the stator winding.
Outer Rotor BLDC Motors: The rotor surrounds the stator winding.

Each type offers unique advantages depending on the application, such as improved cooling or higher torque density.

The Role of Winding Machines
