Hollow AC Servomotors

Direct Drive Servo Motor -- SGM7F
from Yaskawa America, Inc. - Motion Division

Directly connect a load to SGM7F and get backlash-free torsional stiffness in a compact package that makes application easier. An iron core design is coupled with a high resolution 24-bit encoder to achieve highly accurate indexing. A smaller size and low heat generation make SGM7F easier to... [See More]
