Sigma SD Spindle Motor

Sigma SD Spindle Motor

A specialty servo motor engineered to meet the unique performance demands of machine tools. Built to function with exceptional efficiency and precision at a wide range of speed and torque levels, and constructed to withstand decades of daily stress in high volume production environments.

Sigma SD Spindle Motor Features

Sigma SD spindle motors are a proven success in the machining industry’s most sophisticated equipment. This distinction comes from their ability to function with precision at extremely high speeds, while also responding readily to the low speed, high torque demands of tapping and other specialty applications.

• Wide power range
  Up to 45kW in 200 VAC. Up to 22kw in 400 VAC
• High speed motor
  Shortens cutting times, boosts throughput and maximized productivity
• Low intertia performance
  Maintains precise speed control despite rapid changes in spindle speed
• Optimized spindle motor
  Improved winding design and cooling structure produce high efficiency, reduced weight
• 200% of continuous power for 10 seconds
  Provides higher accel and decel rates reducing cycle times
• Gain switching
  Creates easier transitions between gain levels, improving spindle orient function and enhancing rigid tapping performance
