SK motors are compact and highly dynamic permanent magnet synchronous servo motors for spindle applications up to 20 kW that offer customer better surface finish, shorter cycle time and longer tool life. Delivered as separate components to be integrated into the mechanical structure of the machine, SK motors offer constant torque capabilities over a wide speed range.

Markets:
• Machine Tools

Features/Benefits:
• Permanent magnet synchronous motor kit
• Parker SK Series Kit Spindle Motors include
    - a rotor with permanent magnets which can, on request, be mounted on customer's shaft
    - a wound stator which can, on request, be designed with a cooling jacket or integrated into customer's mechanics
• Kit solution leading to simplified mechanical designs
• High dynamic performance and power density
    - increased productivity and to reduced size compared to induction motors
• Cold permanent magnet technology
