Industrial motor Ex e

Категория: Электродвигатели

Loher Motors with type of protection "e" (increase safety) distinguish themselves as the various components are optimally harmonized with one another (winding / rotor and components). This is the reason that special construction regulations also apply for these motors. When compared to motors with a flameproof enclosure, which makes any ignition non-hazardous, the protection philosophy for these motors is to avoid ignition, even when a fault situation occurs. The permissible winding temperatures are reduced, which in turn results in a longer lifetime and a low risk of ignition. Fault situation "locked rotor": Loher Ex e motors set themselves apart as a result of the higher (than specified) safe locked rotor time - tE - this makes drive monitoring simpler, safer and uncritical. "Increased safety" therefore also involves a longer service life and especially a higher degree of reliability and operational safety.

Features

Options:

• Regreasing system from FS 160 - SPM nipple from FS 132 - stainless steel screws/bolts - larger connection system
