Driving Great Britain
The engineer’s choice
BCIfor Great Britain
DC-motors move your country
No-frills engineering and ease of use have helped the compact DC brush motor become one of industry’s
most widely used standard products. Whether they are to be found in machinery, doors, vehicles, hospitals
or even out on the golf course, they are the driving force in Great Britain. Although they are often put to
use in quite basic applications, even these pose requirements that need to be fulfilled in the best possible
way – we wouldn’t be ebm-papst if we didn’t have a first-class solution.
BCI – standard product, benchmark quality
The excellent quality, reliability and long service life of our BCI series are what make the difference. Embody-
ing our engineers’ best ideas in every single detail, each BCI excels in terms of performance, load rating and
flexibility. And thanks to the high quality standards maintained at ebm-papst, they are extremely well made.
Their versatility makes this product range a suitable drive solution in countless applications. Whatever your
voltage and installation space requirements, we can provide the appropriate combination of gearboxes,
sensors and brakes, all of which will also be available from your ebm-papst distribution partner very soon.
Do you want to help us get Great Britain moving? Just pick up the phone and call us! More information
about BCI can also be found online.
