Speed - Torque Curve
- Instantaneous maximum torque line: This torque represents the peak load impact when the motor starts. If exceeded, the driver’s over-current protection will trigger, stopping the motor.
- Short-time operation area: The BLDC motor can operate briefly within this torque range at various speeds. Prolonged operation may cause overheating, potentially leading to motor shutdown or damage.
- Rated operating torque line: At different speeds, this torque level is the electric DC motor’s rated load, allowing long-duration operation without issues.
- Continuous operating area: The brushless motor can run continuously within this zone at varying speeds, maintaining stable operation.

Applications
Q: What is a BLDC motor?
A: A BLDC motor, or Brushless DC motor, is a type of electric motor that operates without the brushes and commutator found in traditional DC motors. Instead, it uses motor controllers to switch current in the motor windings, generating a rotating magnetic field that drives the rotor. The rotor typically contains permanent magnets, while the stator holds the windings. BLDC electric motors offer several advantages, including higher efficiency, longer lifespan, and lower maintenance due to the absence of brush wear. They also deliver precise speed and torque control, making them ideal for applications in robotics, drones, electric vehicles, HVAC systems, and industrial automation. Brushless DC motors come in two main types: inrunner and outrunner, depending on whether the rotor is inside or outside the stator. With their compact size and high power-to-weight ratio, BLDC motors are widely used in modern devices requiring reliable, efficient, and quiet motor performance.
