24V NEMA17 42BLS40/42JMG50K Square Body Brushless Planetary Gearbox Motor , high speed 6500rpm, Torque range0.5~5N.m
Brushless DC motor technology offer several advantages including high torque to weight ratio, increased efficiency and reliability, reduced noise and longer lifetime compared to brushed DC motors.
One of the benefits of DC brushless motors with internal rotor, lies in their better dissipation of the generated heat. Thanks to the reduced air gap in brushless DC slotted motors, the flux density is higher and torque production is more effective and efficient. JUNQI International slotted BLDC motor range offers diameters from 22 to 86mm with rated torque up to 2.2Nm.
Features:
1. Wide Speed Range, Flat Torque
2. Compact And High Power
3. Excellent Speed Stability
4. High Efficiency And Energy-Saving
