Dunkermotoren GR 63S DC motor

M Rutty & Co has announced Dunkermotoren’s DC motor GR 63S that complements the gap between the GR 63 to GR 80 with an output power up to 120 W.

High output 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 GR 63S torque compared with the same sized standard motor GR63 has increased by 37%, from 27 to 37 Ncm at almost identical nominal speed. The power density has also improved from 0.26 W/cm³ to 0.31 W/cm³.

The mechanical dimensions and interfaces are identical with the GR 63. The motor is available in different rated voltages of 24, 48 and 60 DC with flying leads. Different shaft lengths and diameters and shafts on both sides can be ordered.

Standard is protection class IP50, higher class available on request. The motor is characterised by a minimum of emitted interference, versions with higher protection against interference available on request.

In combination with the modular system, drive solutions based on brushless DC-servomotors (up to 500 W) can be produced at short notice. Other components include planetary gearboxes (up to 160 Nm) and worm gearboxes (up to 30 Nm).
