Frameless Spindle Servo Motors - SKW Series

Parker SKW Series Frameless Spindle Servo Motors – Compact and highly dynamic motor solutions for multi-spindle applications

The SKW series comprises compact and highly dynamic permanent magnet synchronous motors designed as frameless spindle servo motor kits for integration into the mechanical structure of the machine. These motors offer constant torque capabilities over a wide speed range and are ideal for applications requiring high precision and productivity.

Key Features:

• Permanent magnet synchronous motor kit
• Rotor with permanent magnets – can be mounted on customer's shaft upon request
• Wound stator set – can be designed with cooling jacket or integrated directly into machine mechanics
• High dynamic performance and power density
• Cold permanent magnet technology – reduced bearing heating compared to induction motors
• Increased internal diameter – enhanced rigidity and greater capacity for bar stock handling in automatic lathes
• Compatible with Parker's cost-effective sensorless drives
• Simple, light and compact machine design

Specifications:

• Power ratings up to 21 kW
• Speeds up to 12,000 min⁻¹
• 400VAC winding voltage
• Suitable for tooling machines and multi-spindle lathes

The SKW series enables simplified mechanical design by delivering the motor as separate components that can be easily integrated into customer constructions. This results in increased productivity, reduced size compared to induction motors, and improved reliability with minimal maintenance requirements.
