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.
