For the high requirements of the modern electrical drive technology with the use of D.C. current with static inverter supply a new conception was created for the operating of motors with a large range of control, so that it works better in an variable environment of quick changing RPM´s during  the production process .

This is evident by: 

1. Good commutation characteristics also free direct current, 
2. Spark free and infinitely variable  in regular and controlled operation 
3. Smaller dimensions, connection dimension according to the 
     International Electronical Commission, enclosure IP 44. 

With our D.C. motor models in the sizes of 80 to 200 according to the International Electronical Commission  these demands are fully meet. Whereby not only substantial technical advantages are obtained in relation to  the conventional design, but also a volume saving of up to 40 %.

We implement our D.C. motors with four totally plated poles, whereby we do not sacrifice the outstanding  characteristics of the compensation coil or the commutator.

The main field distortion is suppressed by the compensation coil, so that DIERKING D.C motors also work  with perfect commutation in spite of power surges much higher than the rated current.

The four poles model of our D.C. motors with totally plated poles, contributes among other things substantially to the smaller design. 

This manufacturing method is favorable for the cooling of the coil by direct heat dissipation over the grey cast iron housing to the cooling fins. 

Infinitely variable operation in running environment, also under extreme conditions. 

The slots for the admission of the compensation coil are provided with high strewing bar for the increase of  anchor circle inductance: 

For the improvement of the crest factor (FF) during static inverter supply thereby a smaller auxiliary 
inductance (anchor throttle) is needed. 

In addition noises are to a very large extent avoided. 

DIERKING D.C. motors with measurement in accordance with the International Electronical Commission are  supplied in all designs according to DIN 42 950/4.64. 

Combined with the DIERKING transmissions for the low speed range, they form a compact, graceful 
designed unit. 

For the most diverse operation conditions of the electronically controlled technology the D.C. maschine with direct current speedometer or alternating current speedometer can ventilated it self or through a secondary system  and be implemented with the most different brakes. 
 

Custom built models are always possible.
