DK42AL Drill Motor

DK42AL Drill Motor


With the DK42AL Traxx has extended the successful series of powerful Drill Motors up to 400 mm drilling diameter.
A robust, powerful and solid three-phase motor with an appropriate high capacity gear system is packed in a stable aluminum case. Due to an optimized motor cooling by using water, an excellent power to weight is achieved.


3 - gear gearing unit

High efficiency gearing unit with economic speed adjustment to each bore diameter as well as a wide drilling range (diameter 70 - 400 mm).

Oil bath lubrication

Optimal gear lubrication for high efficiency and durability and less maintenance.

Safety clutch - Indispensable safety element.
Protects operator as well as machine and tools from mechanical overstrain.

Three-Phase Motor

Extremely durable and low maintenance motor without brushes and collector. This motor has only a simple rotor instead of a coiled armature. It is silent. The speed drop at full power is minimal.

Motor protection

The DK42AL is protected by thermal switches integrated in the stator windings. Therefore the motor is protected directly in case of overload, unsymmetrical voltage or phase failing.

Motor cooling

The DK42AL's motor is cooled by a patented water cooling.
The cooling water flows controlled through the interspace between case sleeve and motorcase.
Due to this intensive cooling power output and weight is improved considerably.

Metal casing - makes the DK42AL

Contrary to plastics cases - mechanically and thermally solid and stable. The DK42AL is switched by an on-off button on the top of the machine via a conductor. For saving weight it is fitted in a cable case. By this device the motor is solidly and exactly switched and the required undervoltage trip is realized.

The DK42AL corresponds to the water protection class IP 55, i.e. water cannot enter into the motor during proper use. Thus it is possible to drill upwards in a vertical position without taking any further precautions (overhead drilling).
