42mm 3phase 24V 77.5w 24:1 speed ratio Brushless Planetary Gear Motor
A Brushless DC Motor is operated by means of an electronic six-step commutation system. Unlike its Brush DC Motor counterparts, the Brushless DC Motor does not contain any carbon brushes. Instead, the electromagnets within the motor remain stationary along with the armature, while the encased permanent magnets rotate, generating torque. The Brushless DC Motor is synchronous; both the stator and the magnetic field generate the same frequency, therefore avoiding any type of "slip" most induction motors exhibit.

4.Related Qualification Certificate:
Blushless Dc Motors employ electronic commutation instead of mechanical commutation to convert direct currents into alternating currents. While brushed DC motors have windings on the armature connected to commutators at one end, brushless dc motors have transistors arranged in a specific configuration that applies pulses to a coil, causing the magnet to spin. Thanks to this and other benefits Blushless dc motors offer, they're well suited for motion-control, positioning, and actuation systems. Custom Blushless dc motor manufacturers build the devices for use with linear motors, servomotors, CNC machine tool feed drives, extruder drive motors, and industrial robots with actuators.
