SN3/SN4 Series AC Synchronous Motors provide high performance

in two frame sizes, NEMA 34 and 42 (90 and 110 mm).

Resistor-capacitor kits are also available. These motors are driven

economically from standard AC line voltage and the synchronous

speed is related to the line frequency.

ratings from 198 to 636 N-cm (280 to 900 oz-in)

• SN4 models: NEMA 42 (110 mm), three stack lengths with torque

ratings from 500 to 1059 N-cm (715 to 1500 oz-in)

• All models offer flying lead, terminal box, connector and shaft

extension options

• 72 rpm motor speed (with 60 Hz voltage)

• Constant speed does not vary with load

• 120 volt AC models

• Fast starting, stopping and reversing

• Can be stalled indefinitely without overheating

• Standard connections include leaded, terminal box, MS connectors,

rear shaft

Choose Your Optimum Linear Motor Design

The IC Ironcore DDL is our most powerful, versatile model, ideal for moving

heavy loads quickly or for accommodating global applications at 230/400/480

bus voltages without the need for transformers. The ICD Ironcore Low Profile

DDL offers outstanding force density, allowing you to design the most compact,

lightweight applications. And the IL Ironless DDL offers zero-cogging performance

for applications that require very low bearing friction, high acceleration of lighter

loads and smooth operation even at ultra-low speeds.

Features

•Ideal for accelerating and moving low to very high masses — greatest rated thrust

force per size

•Suitable for global markets — 230/400/480 VAC bus voltage for IC Ironcore DDL

•Very smooth velocity with high positional accuracy — zero backlash or compliance,

maintaining the stiffness required for machining and other process forces

•Zero maintenance — eliminates lubrication and wear of ball screws, gearboxes,

rack and pinions, or belts and pulleys

•Simple, compact mechanical assembly — high force density in a minimal form factor

with a greatly reduced total parts countKollmorgen Direct Drive Linear Motors

DDL motors drive linear loads directly, eliminating the need for couplings,

belts, ball/lead screws, rack & pinion gears or other backlash-prone,

maintenance-intensive transmission components. Using direct drive linear

motors, your machine can be simpler to design, faster and more precise

in operation, quieter and more reliable — without the need for complicated

parts that require constant lubrication and eventually wear out.

Pair your DDL motor with an AKD or AKD2G servo drive for industry-leading

power density, flexible communication options and optional functional

safety capabilities.

A Direct Drive Linear Motor for Every Application

Kollmorgen DDL motors offer the broadest selection of input power and force

density to meet your specific application requirements. The IC Ironcore DDL

series handles medium and high-voltage applications requiring peak force up

to 13.448 N. The ICD Ironcore Low Profile DDL is ideal for use in compact

applications. And the IL Ironless DDL offers zero cogging and exceptionally

light mass.

Features

• D Series: 240 VAC line power

• DH Series: 400/480 VAC line power

• 5.3 to 115 N-m (3.9 to 85 lb-ft) continuous torque

accommodates a wide range of application requirements

• Speeds up to 800 rpm meet most high torque / low speed

application requirements

• High-resolution sine encoder feedback devices provide

exceptional accuracy and repeatability below one arc-second

• Optional rugged multi-speed resolver feedback provides

reliable operation in harsh environments

• IP65 and 67 shaft sealing resists dust and water jets

• Built-in thermistor provides over-temperature protection

• CE Compliant, UL Recognition for global acceptance

Housed D & DH

Kollmorgen Housed Direct Drive Rotary (DDR) motors offer high

performance and zero maintenance in a precision servo solution.

These motors combine large diameter, short length and a high

number of magnetic poles to provide outstanding torque density,

while eliminating the need for gearboxes, timing belts and other

transmission components. Our co-engineering capabilities ensure

a right-fit solution for your application.

Benefits

• Provide programmable functionality in indexing systems that far

exceed the throughput of mechanical or variable reluctance

technologies

• Direct load connection eliminates backlash, compliance, maintenance

and eventual replacement of gearboxes, belts or pulleys

• Zero backlash and compliance provides more responsive system

performance

• Eliminates coupling devices, reducing overall machine size

• Single- and dual-bearing designs reduce static friction

Cartridge DDR®

Our exclusive Cartridge DDR® servo motors combine the performance

advantages of a frameless motor with the ease of installation of a

full-frame motor. They feature an integrated, factory-aligned high

resolution feedback device and a unique bearingless design that couples

directly to the load, using the machine’s own bearings to support the

rotor. Most models can be installed in under five minutes.

Features

• 5 frame sizes, multiple lengths

• 230 / 400 / 480 VAC windings available (high and low)

• 4.5 to 510 N-m (3.3 lb-ft to 376 lb-ft) continuous torque accommodates

a wide range of high-power application requirements

• Speeds up to 2.500 rpm meet most medium speed and high torque

application requirements

• Power ratings from 775 to 11.700 watts meet high power demands for

most applications

• Integral sine encoder feedback provides resolution of over 134 million

counts per revolution

• Built-in thermistor provides over-temperature protection

• UL Listed for global acceptance
