More power in a smaller package.

Rugged NEMA 34 and 42 frame hybrid POWERPAC(TM) steppers provide the highest torques per frame size in the industry (up to 5700 oz-in. or 356 lb-in.). Optimal magnetics in a "housingless" frame combine with a large diameter rotor and new rotor-stotor design to produce more torque and provide high acceleration capabilities. This unique design also features low detent torque for smoother microstepping. In addition, POWERPAC runs cooler than comparable size steppers. Since POWERPAC hybrid steppers meet demanding motion requirements, they also make a cost effective alternative to servo motors in applications with moderate speed requirements.

POWERPAC is available in two different designs - the N and K Series - with combinations of standard options routinely provided to customize the motor for your specific requirements. Bipolar or unipolar phase sequencing is readily available, along with a selection of standard and special windings.

Features	Benefits
Highest torque per frame size in the industry - more than 3 and 5 phase designs.	Optimized magnets provide maximum performance in a small envelope, reducing space required for the motor.
Improved torque linearity (above rated current) provides high peak torque capability (contact factory for details)	Acceleration boost to move loads faster. Provides more torque for intermittent duty applications.
High torque at moderate speeds.	Cost effective alternative to servo motors
Low detent torque harmonic.	Provides smoother microstepping performance
K Series uses patented Sigmax(R) technology to develop 25 per cent more torque than N Series plus even higher acceleration.	Select from broad performance range to meet your requirement
Runs cooler than comparable steppers using identical drive parameters.	Longer, more reliable motor life- backed by a two year warranty
Special rotor design for high acceleration	Move/position loads fast
Rugged "housingless" square frame	Efficient use of volume for optimal magnetic circuit
Sealed per IP65	For splashproof requirements

Outer bearing races won't turn.	Long life bearings - also prevents axial shaft movement for encoder applications.
Extensive selection of shaft configurations, terminations, standard and special windings.	Match your requirements
Two phase design	Compatible with most drivers, smoother microstepping, and lower input power required vs. Three phase for same torque.
Optional encoder	Optimizes control scheme
