Direct Drive Technology

SKA Direct Drive RotativeTorque motors

Multipoles permanent magnet synchronous brushless motors. The SKA DDR series is available in the Frameless version formed

by the rotor and stator parts alone so that it can be integrated into machines. A Power Pack version is also available, with flange,

bearings feedback and connections.

2Nm to 760Nm stall torque Thermal protector (clixon) Class F insulation IP65 protection degree (Power Pack solution)

All SKA motors feature these advantages of Direct Drive technology:

SKA motors replace all transmission mechanical components (like gearboxes, screws, belts, pulleys, racks) bypass the

limits given by backlash, friction and inertia enhance manufactured throughput and reliability improve motion linearity and

precision decrease noise levels distribute power and motion control intelligence in the machine simplify and accelerate

the design and assembly of the machine save energy in machine operation reduce costs.
