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-stator 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
