FAQ

What is the significance of the ‘MJG’ grade on this Mersen carbon brush?

The ‘MJG’ designation refers to the specific carbon-graphite composition of the brush. Different grades have varying properties such as hardness, conductivity, and friction, making them suitable for different motor speeds, loads, and environmental conditions. Using the correct grade is crucial for motor performance and longevity.

How do I know when to replace the carbon brushes in my motor?

Carbon brushes should be inspected regularly for wear. They typically have a wear line indicator. Replacement is necessary when the brush has worn down close to this line, or if you notice increased sparking, poor motor performance, or erratic operation. Replacing them before they are completely worn prevents damage to the motor’s commutator.

Is it important to use a matched pair of brushes like this set?

Yes, it is highly recommended to replace brushes in pairs. This ensures even pressure and electrical contact on the commutator, leading to balanced motor performance and preventing uneven wear, which could cause operational issues or damage.
