The high quality of our carbon brushes shows itself in
very low level of wear and dustiness
low stickiness of carbon dust on the brush holders' surface
purer motor space inside
high reliability in operation
low danger of voltage breakdown
What to do in the case you want to make an order (inquiry) of carbon brushes?
For the determination of optimal carbon brush quality (grade) is helpful to fulfil the technical list of questions.
When it is not possible for you to fulfil the list of questions you can proceed as follows:
1. You can send us your dimensional sketch of the carbon brush, its material grade
(usually marked on its body), type of machine, its current, voltage and power,
number of brushes in the machine
.
 |
 |
| t = tangential |
dimension of the brush in peripheral direction |
| a = axial |
dimension of the brush in parallel direction with the rotation axis |
| r = radial |
dimension of the brush in vertical direction to the rotor axe |
|
2. You can send us your sample of the carbon brush used till this time (if it is possible). Also in this case it is useful to complete your order with information mentioned above.
In case of any problem don't hesitate to contact us. We will be glad to advise you, give you some consultation or send you our catalogue.
