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.
