BLDC Motor

A BLDC Motor (Brushless DC Motor) is an electric motor that uses electronic commutation instead of mechanical brushes to control the flow of current through the motor windings.

Despite the name, a BLDC motor does not operate directly from DC power. A motor controller converts the battery’s DC voltage into three-phase currents that create a rotating magnetic field and produce motion.

BLDC motors are widely used because they offer:

• High efficiency
• High power density
• Low maintenance
• Long service life
• Excellent reliability
• Precise electronic control

BLDC motors are available in many forms, including:

• Outrunner motors
• Inrunner motors
• Hub motors
• Servo motors

A BLDC motor can be operated using different control methods, including BLDC Control and FOC (Field-Oriented Control).

⚠️ A BLDC Motor is a type of motor, not a control method. The motor itself does not determine whether BLDC Control or FOC is used.

Example

A three-phase outrunner motor connected to a VESC controller is a BLDC motor. The controller can operate the motor using either BLDC Control or FOC.

In simple terms: a BLDC motor is a brushless electric motor that uses electronic switching instead of physical brushes.
