Brushless DC Motor 1650NR-01A-24.0 Motor Characteristic Curves
The performance curve graph above presents the comprehensive electromechanical performance analysis of the 1650NR-01A-24.0 Brushless DC Motor operating under a stable nominal supply voltage of 24.0V DC. It clearly illustrates the key relationships between torque, speed, current, output power, and overall motor efficiency.
Key technical performance characteristics shown in the curves include:
- Speed vs. Torque (N-T Curve): Demonstrates the linear torque-speed drop, maintaining a high free-running speed of 31,000 RPM at no-load and delivering a stable 28,000 RPM at the rated torque of 110 g.cm.
- Current vs. Torque (I-T Curve): Shows proportional electrical current consumption scaling linearly from a low no-load current of 65mA up to the peak stall current of 7.2A.
- Output Power & Efficiency Curves (P & η): Highlights the optimal efficiency zone where the motor maximizes energy conversion while minimizing heat generation, making it highly suitable for continuous duty in high-speed medical devices and compact blower modules.
Engineers can utilize these performance curves to determine the ideal operating point for optimal energy efficiency and long operational lifespan in custom OEM/ODM applications.
