POWERPAC® hybrid stepper motors deliver more power in a smaller package. These rugged NEMA 34 and 42 (90 and 110 mm) motors combine optimal magnetics in a housingless frame with a large diameter rotor and innovative rotor-stator design to produce more torque and smoother microstepping. The K Series incorporates flux-focusing SIGMAX® technology for higher acceleration with 25 percent more torque.















FEATURES

• Wide range of standard options
• Affordable co-engineered modifications with a short lead time to meet unique application
  requirements
• N3 models, NEMA 34 (90 mm) motors are available in 4 stack lengths with torque ratings from 3.2
  to 15.4 N-m (454 to 2,180 oz-in) nominal holding torque.
• K3 models, NEMA 34 (90 mm) motors are available in 4 stack lengths with torque ratings from
  4.08 to 19.7 N-m (578 to 2,790 oz-in) nominal holding torque.
• N4 models, NEMA 42 (110 mm) motors are available in 3 stack lengths with torque ratings from
  8.12 to 30.8 N-m (1,150 to 4,365 oz-in) nominal holding torque.
• K4 models, NEMA 42 (110 mm) motors are available in 3 stack lengths with torque ratings from ]
  10.4 to 40.3 N-m (1,470 to 5,700 oz-in) nominal holding torque.
• Extensive selection of shaft configurations, terminations, windings and co-engineered
  modifications to suit your application needs, time frame and budget
• Speeds up to 3,000 rpm meet the velocity demands of most high-torque applications
• Improved torque linearity (above rated current) provides high peak torque to boost acceleration in
  intermittent-duty applications
• High torque at moderate speeds to enable a cost-effective alternative to servomotors
• Low detent torque harmonic provides smoother microstepping performance
• K Series incorporates SIGMAX® technology for 25% more torque than N Series
• Runs cooler than comparable steppers to provide longer, more reliable motor life
• Special rotor design enables high acceleration
• Rugged, “housingless” square frame means more torque in a smaller package
• IP65 sealing for splashproof protection
• Two-phase design is compatible with most drives and provides smoother microstepping and lower
  power input versus three-phase motors
• Optional encoder mounting provisions
