SINAMICS S120 offers high performance, productivity and flexibility. Its modular design lets you quickly configure drive systems that fit almost any application.

With SINAMICS S220, experience a new system architecture today for tomorrow’s full potential – your advantage starts now. Powerful. Precise. Progressive

Specially designed Motion-Connect technology and measuring systems for your motion control applications. Facilitates project planning and commissioning.

SIMOTICS Torquemotors are the first choice for maximum precision and productivity on rotary axes. Their direct‑drive design saves space, increases flexibility, reduces maintenance and delivers high torque with excellent dynamics and accuracy. They’re available in two types:

Both are perfectly matched with SINAMICS S120/S220 for high‑performance machine tools and production systems.

Direct drive technology and high pole count deliver outstanding precision, power and dynamic response. This enables short acceleration times, excellent smooth running characteristics and highly accurate motion control.

With no mechanical transmission elements required, you can integrate the motors directly into the machine structure, saving space and minimizing wear and maintenance while providing a high level of system availability.

A high number of poles enables the motors to generate substantial torque even at very low speeds. This enables powerful, efficient performance ideal for demanding rotary applications.

Provides 100 to 7,000 Nm at speeds from 50 to 1,800 rpm, replacing hydraulic and geared systems. As a permanent magnet synchronous drive, it offers efficient, precise motion for demanding industrial applications.

The extremely compact, water-cooled construction offers high power density and stable continuous operation. Ideal for space-restricted machines requiring strong, reliable torque delivery.

Delivered factory assembled with torque arm, clamping element and centering sleeve, enabling simple and safe machine integration. Creates a very stiff drive train for optimal control accuracy.

Supplied as stator and rotor components for direct machine integration, supporting highly precise rotary motion. Ideal for rotary axes, indexing systems and advanced machining applications.

Operates without couplings or gearboxes, requiring significantly less space than conventional drives. The integrated or jacket cooling options support compact machine designs.

The Siemens drive solution replaced the hydraulic drive in the high-performance segment, resulting in shorter cycle durations, significantly reduced production times, energy savings and high positioning accuracy.

The use of torque motors in the mechanical system enables reduced noise and vibrations, fewer spare parts required, lower maintenance needs and increased energy efficiency. The system is highly customizable and easy to maintain.

German glass machinery supplier IPROTEC uses Siemens technology for its drinking-glass blowing machine, which can produce up to 60 glasses per minute, achieving extremely high precision with lower operating and maintenance costs.

SIMOTICS Torquemotors operate as direct drives, eliminating gearboxes, belts and hydraulic assemblies. This avoids mechanical backlash, reduces friction losses and increases stiffness, resulting in higher precision, improved energy efficiency and lower maintenance requirements.

SIMOTICS T-1FW3 complete torque motors are flanged to the machine using torque arms specifically developed for the purpose. An optional clamping element makes it easier to couple the rotor to the machine shaft. The pre-installed mounting set includes the torque arm, clamping element and centering sleeve (only for hollow shafts), making it simple and safe to establish a connection to the motor. This creates a perfectly stiff drive train that can be optimally controlled. For SIMOTICS T-1FW6 built-in torque motors, stator and rotor are supplied as components and are directly integrated in the machine itself. For a complete drive unit, a bearing and an encoder system are required additionally. For installation in the machine, stators and rotors are equipped with flanges with centering surfaces and threaded holes.

SIMOTICS T-1FW3 is ideal for the process industry, plastics, marine systems and metal forming, where high torques and robust drive train stiffness are essential. SIMOTICS T-1FW6 is suited for rotary indexing tables and partial machines, rotary axes (A/B/C for 5 axis machining centers), workpiece spindles and test stands requiring extremely high precision and compact integration.

Both motor families offer highly efficient cooling options. SIMOTICS T‑1FW3 uses a compact water‑cooled design to provide high continuous torque density. SIMOTICS T‑1FW6 is available in several cooling variants depending on motor size: natural cooling, integrated water cooling with one or two circuits, and jacket water cooling. These options provide optimal thermal performance for diverse machine integration requirements.
