Series Overview
L1B is a high-force flat iron-core linear motor with an installation height of 39 mm. Compared to L1A, L1B delivers higher continuous force at the same power dissipation, making it ideal for applications where thermal efficiency is a priority.
The L1B series is available in three coil lengths (100 / 200 / 300 mm) and three widths (25 / 50 / 75 mm), giving 9 model combinations.

Notes
General tolerance: All values ±5% unless otherwise stated.
Special tolerance: Attraction force, cogging force, resistance and inductance values ±10%.
All electrical performance data are based on 25 °C ambient temperature.
The size specified for the air gap d is an auxiliary dimension and may fluctuate. The only technically relevant dimension is the specified overall installation height H, which must be complied with.
A stainless steel cover can be ordered separately for the secondary parts (not included in the standard equipment).
