Features

Stable Speed Control: The 300W BLDC motor maintains a set speed by continuously comparing feedback signals and adjusting voltage, ensuring consistent performance even with load changes.
Compact & High Power: Uses a permanent magnet rotor in a 3 phase design, delivering a thin profile with high power density.
Wide Speed Range: It offers a broader speed control range than AC motors and inverters, providing strong torque from low to high speeds without brushes.
Energy Efficient: Permanent magnet rotor reduces rotor losses, cutting power consumption by over 20% compared to variable frequency induction motors, supporting energy savings.
Built-in Protection: Brushless DC motor includes safety features to protect the equipment system.

Speed - Torque Curve

Instantaneous maximum torque line: The maximum torque briefly affects the load during motor startup. Exceeding this torque triggers the over-current protection in the driver, causing the motor to stop.
Short-time operation area: The motor can operate for short durations within this torque range at varying speeds. Prolonged operation in this area may lead to excessive heat, potentially causing the motor to stop or even burn out.
Rated operating torque line: The rated torque of the motor is maintained at different speeds, allowing for long-term operation at this torque.
Continuous operating area: The BLDC motor can run continuously within this zone at various speeds without overheating or damage.

Q: What causes a BLDC motor to overheat?

A: A BLDC motor may overheat due to overloading, poor ventilation, or running at voltages and currents beyond its rated limits. Prolonged operation in high-torque zones intended for short durations, or issues with the motor controller, can also lead to excessive heat. Ensuring proper cooling, correct driver settings, and operating within specified limits helps prevent overheating.
