Features
- Stable Speed Control: The 50W 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.
Dimension (Unit: mm)
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 the difference between BLDC motors and traditional DC motors?
A: Here are the differences:
- BLDC Motors: These motors don’t have brushes and commutators. Instead, the direction of the current is controlled electronically by a controller. This results in higher efficiency, longer lifespan, and lower maintenance.
- Traditional DC Motors: These have brushes and a commutator to reverse the direction of the current. This introduces friction, wear, and sparks, which leads to lower efficiency and requires more frequent maintenance.
