These motors, designed to satisfy machine tool manufacturers all over the world, offer constant torque capacities over a wide speed range while guaranteeing a very small footprint.
Among the many advantages of this new range of SKW motors compared to asynchronous motors is the use of cold rotor PMAC technology (permanent magnets AC), which means a reduction in the temperature in the bearings - and thus a low effect of Dilation. In addition, an increase in the internal diameter allows greater rigidity and greater handling capacity of bars (in mobile headstock) in automatic lathes.
Despite the increase in internal diameter, the overall dimensions remain extremely compact. Machine tools, especially multi-spindle machines, require motors with a small outside diameter and a large hollow shaft for the passage of bars or tools (thus providing greater productivity). For this reason, SKW motors have been designed as tubular motors and the result gives many end-user benefits. For example, not only does this allow a dedicated speed for each spindle, but also better surface finish, shorter cycle time and longer tool life. These Parker SKW synchronous motors are also maintenance-free (direct drive), produce low noise levels (no gear or lever sounds), are compatible with third-party drives (including FANUC and SIEMENS), and are resistant to The oil.
SKW motors offer high efficiency (90-95%) and are liquid-cooled to optimize performance. Offering a speed range of up to 12,000 rpm, motors are available in four sizes (with four lengths per size); A constant power of 3 to 28 kW and a low speed torque of 4 to 37 Nm, with specific speed / torque performances available on request.
Integrated inside the spindle, the solution is delivered in kit form, implying a simplified mechanical design of the machine.
