Siemens - Safety Modules PROFIsafe
If it's a safety-oriented controller you need, you can't go wrong with the ET 200S Safety Motor Starter Solution PROFIsafe. Both standard and safe communication take place via a single bus system – PROFIBUS or PROFINET with PROFIsafe profile.
One bus system for both standard and safety signals instead of cumbersome wiring – this is just one of the many advantages which our ET 200S Safety Motor Starter Solution PROFIsafe features with regard to considerably reducing overhead during commissioning.
Furthermore, all sensors and actuators can be freely programmed within the distributed safety concept, whatever their I/O station.
Should you wish to switch off actuators selectively, the Motor Starters Failsafe come into play. If just a group switch off is required, then both standard and high-feature motor starters can be used.
Advantages at a glance
* Fail-safe communication via PROFIBUS/PROFINET with PROFIsafe profile
* Plant availability at levels never seen before – with maximum economic viability
* Up to Category 4 according to EN 954-1 – or up to SIL3 according to IEC 61508
* In addition, effective diagnostic functions and hot swapping help to reduce expensive downtimes

Due to extensive use of the latest technology, such as new semiconductor control algorithms and bypass design, the new soft starters are very compact and heat dissipation very low.
There is no need for extra ventilation or bypass contactors. This simplifies installation and keeps panel space at a minimum.

MCD 3000 is a total motor starting solution. Current transformers measure the motor current and provide feedback for controlled motor voltage ramp up, but also for numerous motor protection functions.
A numeric display and logic key pad buttons make programming easy, and an operational status such as motor current is showed via the display.

MCD 100 is a cost effective and extremely compact soft starter for AC motors up to 11 kW, due to a unique semiconductor design.
MCD 100 is a true “fit and forget” product.
Selection can be made on the basis of the motor power – exactly as with traditional contactors.

MODEL SERIES - GEARED MOTORISED POTENTIOMETERS
DC MOTORS WITH POT ASSEMBLY
Design -
Mech-Tex offer various assemblies in which a potentiometer with different gear ratios can be mounted in series of the gear train. Thus the geared DC motor operation can be convert in to a close loop one. Suitable mounting arrangement to mount the potentiometer on the gearhead is provided. Use of suitable reduction gear ratios can make the potentiometer rotate more or less (as per requirement) number of rotations with respect to the output shaft. Thus the reading provided by the potentiometer can be more accurate.

FAULHABER BX4 Series 2232 - Brushless DC Servomotors
New developed compact- design
Reliable and long-lived
With the introduction of the BX4 series of brushless DC servomotors, FAULHABER once again underscores its position as an innovative market leader in highly integrated miniature drive systems. Using the latest production methods, some specially developed by FAULHABER, the company has come up with a modular design that is limited to just a few components and entirely eliminates the need for adhesive-bonded joints. Despite the compact dimensions, the new four-pole concept of the series ensures a high continuous torque of up to 12 mNm, with a flat gradient of the n/M characteristic curve.
Notable features are the smooth running characteristics and the particularly low noise level. Thanks to its electronic commutation, the brushless servo motor series is characterised by a much longer service life than mechanically commutated drives. Whilst in the basic version the commutation is provided by an external control, the flexible motor concept of the BX4 series also offers versions with integrated speed controller or integrated encoder. The encoder version is available in four different preset resolutions: 32, 64, 128, or 256 quadrature impulses per revolution. It is available with an optional line driver and differential output signal. In addition to mechanical speed adjustment, the new planetary gearheads of the 22F series also allow a temporary torque increase up to 1500 mNm. Designed with one to four stages, the precision gearhead in steel 21 offers finely graduated reduction ratios, and the diameters can be combined in conformity with the BX4 drives.

The RDxx is a complete positioning unit which integrates a DC gear-motor, a drive, an encoder and a controller. Profibus, CANopen and RS485 interface are available.
The Rotadrive is capable to move axis to target positions by means of ramps and with backlash compensation.
Thanks to its small dimensions (58x125x105 mm) RDxx can be mounted directly on spindle with Ø14mm and fixed by means of the collar and the anti-rotation pin.
Typical applications of this product is on tool-changers, gauges and packaging machinery.

DC-Motors Series 5/6/7
True values last forever! The same applies to DC motors from Siemens. Even if it has been forecast long ago that the end is nigh for them, we shall retain this technology. After all, in daily use the DC motors have for decades proved their worth; it is therefore not necessary to consider an alternative.
Together with the SIMOREG DC-MASTER drive converter units they form the ideal drive set wherever competitive prices and high availability are required.
