The already high demands on machine cycles,
acceleration and linear travel speeds for drive
systems in handling, transportation and production
are steadily increasing. Whether as highly dynamic
and flexible processing machines for handling or
in pick-and-place applications, the new SL2
synchronous linear motors by SEW-EURODRIVE are the
ideal solution for such requirements. As linear
motion and force is generated directly, no
mechanical transmission elements subject to wear,
such as spindles, ball bearings or toothed belts,
are required. An optimum force-density ratio is
achieved by using the latest winding technology
and a laminated iron core. The SL2 synchronous
linear motor with convection cooling is
practically maintenance-free and offers maximum
reliability and availability, high control
quality, speed and accuracy.
SL2 synchronous linear motors are available in
three designs for speed classes 1, 3 and 6 m/s
(3, 10 and 20 ft/s): SL2 Basic, SL2 Advance System
and SL2 Power System. For longer travel
distances, secondaries are available in different
lengths and can be easily lined up with one
another. The SL2 Advance System features a motor
cooling unit, which provides even better cooling
than SL2 Basic. A forced-air cooling fan gives the
SL2 Power System a further power boost.

Accessories and options for linear servomotors
AL1H length measuring system
SEW-EURODRIVE can equip the SL2 Advance System and SL2 Power
System linear servomotors with the AL1H absolute length
measuring system. AL1H consists of a linear sensor, which is
attached to the motor cooling unit along with the encoder
components, and a measuring tape, which is routed along the
travel section. The AL1H length measuring system is
dirt-resistant and permits high speeds and acceleration.
Encoder components that are ready for use facilitate fast,
simple and cost-effective mounting of the AL1H.
Prefabricated cables for linear servomotors
SEW-EURODRIVE offers optional prefabricated power and
feedback cables for SL2 Advance System and SL2 Power System
linear servomotors, enabling straightforward and reliable
connection.
Power cables are fitted with the appropriate plug connector
on the motor side. The shield is connected in the connector
housing according to EMC requirements. All plug connectors
seal the plug on the cable end with a lamellar seal and
ensure strain relief in accordance with EN 61884. On the
inverter side, the single conductors are exposed, and the
shield is ready for connection in the control cabinet. The
parts included allow you to customize the single conductors
specifically for your inverter.
The encoder end of the feedback cable is ready for
connection to the AL1H length measuring system. A
commercial sub-D EMC connector with pin contacts is used on
the inverter end. A 9-pin or 15-pin plug is used, depending
on the inverter used.
