The 1PH8 family of high-performance induction motor drives and servomotors offer assorted bearing designs for increased cantilever forces or increased speeds up to 20,000 rpm.

After considerable research and product refinement, as well as extensive field contacts with end-users, Siemens Industry, Inc. (Chicago, IL) has introduced the new 1PH8 family of high-performance induction motor drives and servomotors. Available in a wide power range, from 2.8 up to 1340 kW, these new motors provide excellent dynamic response, smoother operation, and lower vibration levels, and offer:

• Assorted bearing designs for increased cantilever forces or increased speeds up to 20,000 rpm.
• Shaft designs in a solid or hollow configuration to match the mechanical interface.
• Forced-air or water-cooled models for choosing the better method to suit the job.
• Induction or synchronous servomotor design for mating the right motor to the size requirements and dynamic response needs; both styles feature the same mechanical and electrical interface to simplify engineering.
• Absolute or incremental encoders built-in for high-resolution feedback and enhanced motion control in high power level applications.
