Lathe Spindle Drives
Altec provides both AC and DC lathe spindle drives using the latest drive technology from Allen-Bradley and ABB. Our AC lathe spindle drive package features a low-inertia, 500 HP, 1800 RPM AC motor and regenerative AC VFD from ABB which has achieved speeds as high as 3000 RPM at core limit. Stopping time from 2800 RPM is 0.9 seconds and only 0.7 seconds from 2400 RPM. The advantages of AC lathe spindle drives are improved dynamic performance, better synchronization with downstream drives and elimination of the maintenance costs associated with DC motors.
For customers that prefer to stay with DC technology, we offer the latest DC drive technology from either Allen-Braldey or ABB. We have also provided new DC motors with performance that exceeds that of the traditional DC motors used in this application.
