A BLDC motor, or Brushless dc motor, is a type of electric motor that operates using direct current (DC) electricity but does not use brushes for commutation like traditional brushed motors. Instead, it uses an electronic controller to switch the current to the motor windings, producing a rotating magnetic field that drives the rotor.
A Brushless DC (BLDC) motor is built with several essential components that work together to produce smooth and efficient rotational motion. Below are the main components of a BLDC motor, each playing a critical role in its operation:
The stator is the stationary part of the motor and houses the windings. It is constructed from laminated steel sheets and contains copper wire coils that generate a rotating magnetic field when energized.
Typically arranged in three-phase windings
Creates the electromagnetic field that drives the rotor
Designed to maximize efficiency and reduce losses
The rotor is the rotating part of the motor and contains one or more permanent magnets.
Can have 2 to 8 or more poles
Magnetic field reacts to the stator’s field, producing rotation
In inner rotor motors, the rotor is inside the stator; in outer rotor types, the rotor surrounds the stator
These sensors detect the rotor's position and send signals to the controller to properly commutate the motor.
Ensure precise timing of current switching
Improve control over torque and speed
In sensorless BLDC motors, back-EMF is used instead
The controller is responsible for commutating the motor electronically—replacing the role of brushes in traditional Brushless motors.
Converts DC input into a three-phase AC signal
Determines when and how to energize each coil
Controls speed, torque, and direction of rotation
Bearings support the rotor shaft and allow smooth rotation with minimal friction.
Usually ball bearings
Crucial for motor durability and noise reduction
Designed to handle both radial and axial loads
The shaft is connected to the rotor and transmits mechanical power to the motor’s load.
Typically made from hardened steel
Precisely machined to minimize vibration and wear
The outer casing protects internal components from dust, moisture, and mechanical damage.
Often made of aluminum or steel
May include cooling features such as fins or ventilation
Together, these components form a high-performance, low-maintenance motor that is widely used in modern industries for its efficiency, reliability, and precise control capabilities.
A Brushless DC (BLDC) motor works by converting electrical energy into mechanical energy through the interaction between a rotating magnetic field (from the stator) and permanent magnets (on the rotor). Unlike brushed motors, BLDC motors do not use physical brushes or a mechanical commutator to control current flow. Instead, they rely on an electronic controller to manage commutation.
At its core, the BLDC motor operates based on the Lorentz force law, where a current-carrying conductor in a magnetic field experiences a force. Here's a step-by-step breakdown:
To rotate the motor correctly, the electronic controller needs to know the rotor’s position. This is typically achieved using:
Hall effect sensors, or
Sensorless control via back-EMF (Electromotive Force) detection.
Unlike brushed motors where commutation happens mechanically, in a BLDC motor, commutation is done electronically. Based on the rotor's position, the controller switches current through different stator windings in a precise sequence.
This creates a rotating magnetic field in the stator that continuously "pulls" the rotor’s permanent magnets, causing the rotor to spin.
BLDC motors are typically three-phase motors, with three sets of windings on the stator. The controller energizes the windings in a six-step commutation sequence:
At any point, two phases are active while one is off.
The controller switches the current every 60° of rotor rotation to maintain continuous movement.
This method ensures smooth rotation and consistent torque.
As the stator’s electromagnetic field rotates, it interacts with the fixed magnetic field of the rotor’s permanent magnets. This interaction produces torque, which turns the rotor.
The faster the controller switches the magnetic field, the faster the rotor spins—this controls the speed of the motor.
Speed can be controlled by adjusting:
Voltage to the motor
Pulse Width Modulation (PWM) of the supply signal
Torque is directly proportional to the current flowing through the windings. Higher current = more torque.
In advanced applications, BLDC motors can perform regenerative braking, where kinetic energy is converted back into electrical energy and returned to the power source.
Rotor: Contains permanent magnets and rotates.
Stator: Contains windings that are energized in sequence.
Electronic controller: Manages the switching of currents based on rotor position.
Magnetic interaction: Creates continuous torque and rotation.
No brushes: Results in higher efficiency, less wear, and reduced maintenance.
This brushless design makes BLDC motors ideal for modern applications requiring high performance, long service life, and precise control, such as in electric vehicles, drones, robotics, and industrial automation.
Brushless DC (BLDC) motors are typically classified based on two main criteria: the configuration of the rotor and stator, and the placement of the windings. The most common types are:
