New solutions for Dunkermotoren
Last November at SPS/IPC/DRIVES 2009 Dunkermotoren presented 2 new motors:
the new brushed DC-motor GR 63S and the DC-servo motors now with PROFIBUS DP Interface also.
According to Dunkermotoren, the first motor complements the gap between GR 63 to GR 80 with an output power up to 130 Watts. The high output power results from ferrite magnets with a high flux density and also from the housing of the motor which is dip-coated in plastic paint. This enables a better heat dissipation at the motor housing.
The torque of the GR 63S compared with the same sized standard motor GR63 increase by 37%, from 27 Ncm to 37 Ncm at almost identical nominal speed. The power density also improved from 0,26 W/cm3 to 0,31 W/cm3. The mechanical dimensions and interfaces are identical.
The motor is available in different rated voltages 24, 48 and 60 VDC with flying leads. Different shaft lenghts and diameters and shafts on both sides can be ordered. Standard is protection class IP 50, higher class available on request.
The other new Dunkermotoren solution is related to DC- servo motor family. These compact drives are already available for years with the standard Fieldbus Interface CANopen in accordance with Communication Profile DS 301 and Device Profile DSP 402 .
Now the range is expanded thanks to the well-established Interface Profibus DP V1. Intuitively parameterizing by the help of popular Projection Tools (e.g. SIMATIC Manager) is possible. Prefabricated function modules for programming of standard positioning- and velocity modes are included in the scope of delivery.
