Brushed and brushless DC motors
General characteristics
Elnor offers custom-designed DC motors (with internal brushes or brushless), ATEX and IECEx approved.
​
A new brushless DC motor design is launched at OTC 2023 in Houston. See Motor Specifications below.
Explosion-proof range of DC motors
As the development of explosion-proof DC motors is complex, it is worthwhile considering custom motors. Elnor is able to take many engine aspects to heart at the same time: dimensions, noise & vibration, drive and multiple mains support as well as axle and flange adaptation, mounting, high-durable painting, etc.
