AC Drives
Power Modules PM240-2 :-

PM240-2 Power Modules have a braking chopper (four-quadrant applications) and are suitable for a large number of applications in general machinery construction.

Power Modules PM250 :-

PM250 Power Modules are suitable for the same applications as the PM240 Power Modules. Any braking energy is directly fed back into the line supply (four quadrant applications - a braking chopper is not required).


SINAMICS G130 chassis units have been designed for variable-speed drives in machine building and plant construction.

They have been specially tuned to the requirements of drives with quadratic or constant load characteristics with medium performance requirements without regenerative feedback.

The control accuracy of the sensorless vector control is suitable for most applications, and additional actual speed value encoders are therefore superfluous.

SINAMICS G130 offer an economical drive solution which can be matched to the respective customer requirements by a wide range of components and options.

Features :-

SINAMICS G130 provides a modular drive system for machine builders and plant constructors which permits a drive solution tailored to their applications. SINAMICS G130 consists of two modular, stand-alone components:

- Power Module and
- Control Unit.

The units can be located separately or combined together. The power module contains a space for the control unit.

The user-friendly AOP30 operator panel is available for start-up and local operation. Predefined interfaces, either via a terminal block or PROFIBUS, facilitate drive start-up and control. The interfaces of the control unit can be supplemented by additional modules.

Typical applications :-

Pumps, Fans, Compressors

Moving: Belt conveyors 

Processing: Mills, mixers, kneaders, crushers, agitators, rotary furnaces, extruders


Even in the world of drives, there are often forces which are difficult to control. Until the most powerful of our frequency inverters enters the field. The MICROMASTER 440 has been specially designed for those applications which require broader functionality and a greater dynamic response than is usually the case. The sophisticated vector control system ensures a uniformly high drive quality, even when sudden load changes occur. Fast response inputs and positioning deceleration ramps allow movement to target positions even without an encoder. Due to an integrated brake chopper, it works with outstanding precision, even during braking and short declaration ramps. All this is possible within a power range starting at 0.12 kW (0.16 HP) and going up to 250 kW (350 HP).
