XDC Precision Customer Feedback
What we appreciate most about XDC is how fast they reply. If there’s ever a delay or any issue, they tell us directly instead of hiding it. That makes planning on our side much easier. Their attitude is very straightforward and cooperative.
We tried a few suppliers before, but either the price was too high or the quality was unstable. XDC gave us a very reasonable price, and the commutators are performing well in our tools. Our failure rate in testing has clearly gone down since we switched to them.
During a new motor project, XDC helped us adjust the design of the commutator several times. They gave practical suggestions instead of just doing exactly what we asked. That saved us time and a lot of trial and error. We’re very satisfied with the technical support from their team.
We’ve placed some urgent orders with XDC, especially before peak season. They managed to deliver on time and kept us updated on the production schedule. This helped us avoid shortages and kept our production line running smoothly.
We’re based in Europe and were a bit worried about the time difference at first. But the XDC sales team arranges calls at times that work for us, and emails are answered quickly. The communication has been very smooth, so the distance hasn’t been a problem.
FAQ: Function of Split Ring Commutator and Working Principles
The function of split ring commutator in a DC motor is to reverse the direction of current in the armature windings every half-turn. This keeps the torque acting in one direction, so the rotor continues to spin instead of rocking back and forth. Without a correctly designed split ring commutator, the motor would lose smooth, continuous rotation.
In a DC generator, the split ring commutator function is to mechanically rectify the internally generated AC voltage in the armature into DC output at the terminals. The commutator segments and brushes switch the connections so that the external circuit sees a unidirectional voltage, even though the induced EMF in each coil is alternating.
So, how does a split ring commutator work?
- The armature coils are connected to copper segments arranged around the shaft.
- Stationary brushes press lightly on the segment surface.
- As the rotor turns 180°, each coil’s connections swap from one brush to the other.
- This reverses the current in that coil at exactly the moment when the torque would otherwise reverse.
The result is that the magnetic force on the conductors always produces torque in the same rotational direction. XDC optimizes segment geometry, materials and surface finish so that this commutation is as smooth and spark-free as possible.
Choosing the right split commutator involves checking:
- Supply voltage and required current
- Target speed in rpm and duty cycle
- Mechanical envelope (bore, OD, axial length)
- Environment (clean lab, dusty workshop, outdoor use)
- Desired brush type and acceptable maintenance intervals
If you share this information with XDC, our engineers will quickly point you to a standard split ring commutator or design a tailored split ring type commutator to match your motor.
