PLATINUM ® DDL
The Direct Drive Linear (DDL) Story
What is direct drive? Very simply it is the direct coupling of a linear
motor (such as the Kollmorgen PLATINUM® DDL) to the driven
load. With this configuration, all mechanical transmissions, such as
ball/lead screws, rack & pinions, belts/pulleys, and gearboxes are
eliminated. This in turn eliminates backlash and compliance and
other problems associated with these mechanical transmissions.
The DDL Benefits:
• ZERO maintenance
• No ball screws, gearboxes, rack & pinions, belts/pulleys
• Zero backlash and compliance
• High stiffness
• High positional accuracy
• Compact mechanical assembly
• Reduced parts count in machine
• Very smooth velocity
• Quiet operation
The PLATINUM DDL linear motor line provides a new dimension in
performance with higher throughput, accuracy, and zero maintenance.
Kollmorgen PLATINUM DDL
Kollmorgen supplied its first linear motors in the late 1970’s for use
in precision X-Y tables and coating systems. These were brush DC
motors using the Kollmorgen patented push-through commutator
bar method. This led to development in the early 1980’s of the
brushless versions of the linear motor which were used in film
processing applications where smooth, high stiffness, linear motion
was required. During the past 10 years, advances in permanent
magnet material, power semiconductors, and microprocessor
technology have been the enablers for increased performance and
lower costs for linear motors.
These developments have been refined into the Kollmorgen
PLATINUM DDL product line of easily applied, cost effective linear
motor components. The product line consists of two fundamental
constructions, Ironless and Ironcore. The Ironless motors have no
attractive force between the frameless components and have Zero
cogging for ultra smooth motion. The Ironcore motors provide the
highest force per frame size. They feature a patented anti-cogging
design which yields extremely smooth operation from these high
force motors.
Standard Features:
Ironless:
• Peak force 60 to 1600 N (13.6 to 360 lbf)
• Continuous force 21 to 450 N (4.6 to 101 lbf)
• Zero cogging
• Zero attractive force
• Smooth motion for speed as low as 1 micron/second
(0.00004 in/sec)
• Low mass coil assembly for high acceleration
Ironcore:
• Peak force IC series: 190 to 15625 N (43 to 3513 lbf)
• Continuous force IC series: 73 to 12023 N (16 to 2703 lbf)
• Peak force ICD series: 170 to 1130 N (38 to 254 lbf)
• Continuous force ICD series: 57 to 315 N (13 to 71 lbf)
• Patented anti-cogging technique for minimal cogging
without magnet skewing
• High motor constant (Km)
• High force density
• ICD Series Advantage:
– Very low profile
– Low attraction force
– Suitable to replace many Ironless applications
