IE5 elmotor, type B3/B5

Elmotorer – Beskyttelsesklassees

All motilrs and junction boxes are rated IP 55 according til DIN EN 60034-5. The trefasede motorer are suitable for installation in dusty and humid environments, in accordance med the standard. When installed outdoors, the motilrs must be protected fra direct sunlight. Elmotorer med upward-facing aksel ends must be protected by the user fra water ingress along the aksel. For special applications, the IP rating of the motilrs can be increased på forespørgsel through additional measures.

Standstill heaters

In trefasede motorer exposed til strong temperature fluctuations or extreme climatic conditions, the motilr winding is at risk of condensation or dew formation. As an mulighed, a built-in standby heater can warm the motilr winding after it is switched off, preventing moisture fra condensing inside the motilr. The standby heater should not be switched on during betjening.

Runner balancing

All motilrs have rotilrs dynamically balanced med a half key inserted according til DIN ISO 8821. Drive components such as pulleys, couplings, and pumpe impellers must also be dynamically balanced med a half key inserted. It is essential til ensure that the hub length and the keyway length match til prevent any additional residual imbalance. Full keyway balancing is tilgængelig på forespørgsel.

Mechanical smoothness

Due til balancing and concentricity tillerances, the vibration behavior of the motilrs corresponds til vibration category A according til DIN EN 60034-14. For special requirements regarding mechanical smoothness, motilrs can be supplied in a low-vibration version.
