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 can briefly handle this torque range across various speeds. Extended use may cause overheating 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 performance loss.
- Continuous operating area: The BLDC motor runs reliably within this zone at various speeds, ensuring efficient and steady performance.

Applications
Q: Why are brushless DC motors better?
A: Brushless DC (BLDC) motors are generally considered superior to brushed DC motors due to several key advantages: higher efficiency, longer lifespan, better speed control, and reduced maintenance. They achieve these benefits by eliminating the brushes and commutator found in brushed motors, which are prone to wear and friction.
