Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Kollmorgen part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 3 series from our supply network are the closest match on published figures.
U-channel ironless linear motors with zero cogging, six sizes from 3 N to nearly 2 kN continuous, for fast settling precision stages.
| Published maximum | IL Ironless DDL | AUM |
|---|---|---|
| Peak force | 1,600 N | 16,200 N meets or exceeds |
| Continuous force | 262 N | 1,980 N meets or exceeds |
| Speed | — | 5 m/s |
Vacuum-compatible ironless linear motors with high motor constant and zero cogging, six sizes.
| Published maximum | IL Ironless DDL | AWM |
|---|---|---|
| Peak force | 1,600 N | 3,845.3 N meets or exceeds |
| Continuous force | 262 N | 769.1 N meets or exceeds |
| Speed | — | 5 m/s |
High-force iron-core linear motors in five widths with optional water cooling, reaching several kN continuous.
| Published maximum | IL Ironless DDL | AKM |
|---|---|---|
| Peak force | 1,600 N | 12,884.3 N meets or exceeds |
| Continuous force | 262 N | 6,190.1 N meets or exceeds |
| Speed | — | 5 m/s |
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
