Overview of the special heavy duty version; Option L03
In many machining processes in the industrial environment, the tools and machining
equipment are subjected to extreme mechanical stresses. This is the case in metal forming
for example, but also in machining processes in which extremely high forces must be
applied.
Also the trend towards greater productivity and more refined products requiring the use of
more complex machining techniques demands the use of state-of-the-art but also extremely
rugged drive systems and automation technology.

Siemens is offering, with the complete 1FW3 Heavy Duty torque motor, a direct drive that
addresses the following requirements.
The powerful, permanent-magnet synchronous motor is characterized on the one hand by its
high dynamic response and precision. On the other hand, the motor has a mechanically
rugged design, enabling it to resist shocks in the range of up to 10 g without any difficulty.
1FW3 Heavy Duty torque motors are ideally suited to address the following motion profiles
with high demands on the dynamic performance of higher-level motion controllers even
under harsh operating conditions.
In contrast to motor/gearbox combinations, the complete 1FW3 Heavy Duty torque motor is
characterized not only by its enhanced ruggedness, but also by its compactness. These
characteristics make it particularly suitable as a main drive in servo presses.
The Heavy Duty version is defined by specifying L03. Shaft heights 200 and 280 are
available. For an additional mechanical description, refer to Chapter "Heavy Duty (Z option
L03) (Page 149)" in the Installation chapter.
