Kollmorgen POWERPAC® K/N Series Stepper Motorstor

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 coengineered 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 servo motors

» 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

K/N Series

The K/N Series are larger step motors with the power, rugged construction,

and options that make these motors ideal for heavy industrial applications.

Options include:

IP65. terminal boxes and MS connectors. Enhanced versions provide the

maximum performance torque available. This patented technology boosts

torque an additional 25% to 40%. Custom motors are available to meet

specific application needs including: modified shafts, connectors, lead-

screws, and components mounted to the shaft.

K/N Series Benefits

»More torque to drive heavy loads

»Smaller drives result in a lower system cost

»Higher efficiency enables lower operating costs
