Reduced and Predictable Maintenance
A low level of maintenance is an important customer requirement. But it is just as important for the customer to be able to draw up reliable plans for the maintenance intervals without any unforeseen disturbances occurring between them. The DMI motor has not only been designed to
reduce the maintenance needs. Its built-in margins increase the reliability and the possibility to
predict with certainty the maintenance needs.
The DMI motors have the following features:
- Large commutation margin. Thereby optimum brush grade can be selected
- Long brush wear length
- Very good commutator shape stability which decreases the brush wear
- Small commutator diameter which decreases the brush wear (see picture)
- Small sealing gaps in the bearings. No risk of grease leakage into the motor (provided the correct grade of grease used). In addition the bearings' resistance to contaminants increases
- Bearings with long lubrication intervals
- Filter with high degree of filtration in the cooling system which results in long cleaning intervals
- High resistance to contaminants which results in long cleaning intervals
The maintenance instructions provide good support for the planning of the maintenance, care and troubleshooting.
