Notes on this data
Conflict: product page gives IC44 max continuous 4,786 N (natural) / 6,916 N (water) and peak ~8,400 N; the selection guide gives IC44250 at 5,834 N natural / 8,211 N water continuous and 13,448 N peak (natural). Selection guide values used. 13.5 m/s is the highest rated speed in the extracted tables, not an absolute limit. A high-voltage ICH variant was announced in 2025 but no data was read.

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 series from our supply network is 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 | IC / ICD Ironcore DDL | AUM |
|---|---|---|
| Peak force | 13,448 N | 16,200 N meets or exceeds |
| Continuous force | 8,211 N | 1,980 N |
| Speed | 13.5 m/s | 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.
