1. What Is a Brushless Motor?

A brushless motor (BLDC) is an electronically commutated motor that eliminates the need for physical brushes, reducing friction and wear. Instead, it uses a controller to switch current in the stator windings, creating a magnetic field that drives the rotor. This design offers superior efficiency, lifespan, and precision compared to traditional brushed motors.

Key Components:

• Stator: Stationary coils that generate electromagnetic fields.
• Rotor: Permanent magnets (e.g., neodymium) that rotate in response to stator fields.
• Controller (ESC): Regulates power delivery and timing for precise speed/torque control.
• Sensors or Sensorless Systems: Hall-effect sensors or back-EMF detection for position feedback.

Types of Brushless Motors:

1. Inner Rotor BLDC: Compact design with high-speed capabilities (up to 100,000 RPM), ideal for drones and medical tools.
2. Outer Rotor BLDC: Higher torque at lower speeds, used in robotics and electric vehicles.
3. Axial Flux BLDC: Ultra-efficient for renewable energy systems like wind turbines.
