Witton Kramer

The BD2510B Tachogenerator is famous for its robust construction and for its high accuracyand consistent voltage proportional to speed. Brook Crompton (previously GEC) have beencontinuously manufacturing the same design of tachogenerator for over 40 years, taking careto preserve the special materials and design features which provide its unique performance.With this wealth of experience and knowledge…

MD IC06

The extended MD range of would field dc metric motors employs all the design features and benefits of the established frames MD71 to 132. These IC06 frames cover outputs up to 15 kW at 2100 rpm all encompassed in the 112 & 132 frame sizes. This provides an extension to the MD range where a…

MP

The MP range of d.c. metric motors encompasses the reliability and rugged construction employed in the MP range of d.c. motors but with the adaptability of a permanent magnet design. The frames cover outputs upto 1.7 kW with two cooling forms, and is suitable for operation from pure d.c., thyristor converter or PWM supplies.

MD

The MD range of wound field dc metric motors covers outputs in the range 0.09 kW to 5.5 kW for use on fixed or variable speed applications, operating from thyristor, PWM or pure dc supplies. These motors are of two pole construction with laminated poles. The armature and poles are constructed from high grade, low…
