NEMA17 42mm BLDC Motor, JQ42BLS Series 24VDC, 4000RPM Max torque250mN.m brushless dc motor
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). High efficiency
2). Long operating life
3). Low noise
4). Good temperature rise
5). Good balance
6). The most available design for the optimized running.
