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 are the key advantages of using a 3-phase BLDC motor?
A: A 3-phase BLDC motor offers higher efficiency due to smoother, continuous rotation, reducing energy losses compared to single-phase motors. The BLDC motor also has no brushes, resulting in less maintenance and a longer lifespan. Additionally, 3-phase motors provide more torque for the same power input and offer precise speed and torque control, making them ideal for high-performance applications like electric vehicles. Furthermore, they generate less electromagnetic interference (EMI), ensuring quieter and more reliable operation.
