The Neutral Zone in a DC Motor is a critical space for its function and longevity.
The positioning of the carbon brushes in the Neutral Zone is crucial to prevent sparking at the commutator and maximize the Motor's efficiency:
- Sparking (Commutation)
When an armature coil is short-circuited by the carbon brush, the voltage in this coil should ideally be zero. If too high a voltage were induced there, this would lead to a short-circuit current and strong sparking between the brush and the commutator bar. - Torque
If the carbon brushes are not in the optimal Neutral Zone position, the Motor also no longer has its optimal torque.
The Neutral Zone can be updated in the test field Motor adjusted.
However, the neutral zone tester also allows this to be done in a good approximation, without the Motor .
Key Facts:
- Neutral Zone adjustment with the machine at a standstill
- Very simple and safe adjustment
- Can also ideally be used as a pre-adjustment

Good to know:
The Neutral Zone adjustment
The adjustment of the Neutral Zone is not a Test, but an adjustment measure that takes place with the machine at a standstill.
The Test device/adjustment device is connected to the field winding and the brush bridge. Signals generated by the Test device on the field winding and detected on the brush bridge are evaluated.
The Test device indicates how far the angular position of the brush bridge deviates to the left or right from the optimal Neutral Zone. By adjusting the angle of the brush bridge, the position is aligned so that the smallest bar deflection is achieved. In this position, the brush bridge is mechanically fixed. With this, the process is completed.
