Series Overview
L1C is a water-cooled linear motor with an installation height of 53.5 mm (without cooling plate) / 65.5 mm (with cooling plate) / 66.5 mm (cooling plate + thermal insulation). Compared to L1B, it delivers higher continuous force at the same power dissipation. Cooling options include cooling plate and machine tool thermal insulation.
The L1C series is available in 5 widths (50 / 75 / 100 / 125 / 150 mm) and 4 lengths (100 / 200 / 300 / 400 mm), giving 20 model combinations.

Footnotes
- All values based on 25 °C ambient temperature unless otherwise stated.
- Fu: Limit force, the force when the magnetic circuit is heavily saturated. Exceeding this value risks demagnetization or thermal damage; it must not be used as a design variable, but must be considered for short-circuit braking.
- Fp: Peak force (saturated region), permissible duration depends on motor temperature, typically 1–3 seconds.
- Fpl: Motor force achievable briefly (a few seconds) within the linear dynamic range.
- Fc: Uncooled continuous force, motor force with uniform load on all phases. Assumes heat dissipation area approximately 3 times the primary part surface area via mounting plate.
- Fcw: Water-cooled continuous force, temperature gradient between winding and cooling approximately 100 K. Cooling water supply temperature: 20 °C ± 5 °C.
- km: Motor constant, at winding temperature 100 °C reduces to approximately 0.88 times the 25 °C value. Applies to static operation and linear dynamic range.
- R25: Phase-to-phase winding resistance (25 °C), increases approximately 1.3 times at 100 °C.
- vlim: Limit speed achievable temporarily; above this speed the motor force will decrease. Higher speeds can be achieved at lower current/force.
- Electrical values tolerance ±10%.
- 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).
