Menzel Elektromotoren has manufactured a pump motor for the Red Cross in Syria. The vertical motor will help stabilize the water supply in communities destroyed in the civil war. The pump station operator required a straightforward drop-in replacement for an old V1-type motor, matching the existing mechanical interfaces without any constructional changes. This called for various complex features. The large vertical motor with a shaft height of 800 mm has the unusual cooling type IC 511 (tube cooling), with a smooth round welded steel housing in protection class IP54. Menzel built a special flange and fitted the slip ring motor with a short-circuiting and brush-lifting device, which lifts the carbon brushes after the motor start, thus reducing brush wear as well as the effort needed for regularly cleaning the slip ring chamber. The customer requested Menzel to fit the brush-lifting device on the drive side. The motor manufacturer also implemented this uncommon design expertly and within a manageable budget, including various additional works such as fabricating extension rings. Moreover, the family business manufactured a customized motor shaft and terminal boxes. Before shipping, Menzel thoroughly tested the pump motor, making use of the latest addition to its test field, a 3-MW right-angle gearbox that allows load tests in a vertical position. An independent test technician appointed by the customer supervised the load test. The bespoke motor is rated for 1150 kW, 6300 V, 14841 Nm and 740 rpm.

SAB Bröckskes presents SABdynamic 900 and 910, a new generation of CSA and UL/cUL approved cables – made in Germany for worldwide use. The special cable manufacturer thus extends its range by permanently flexible control and data cables, which are equally suitable for drag chains and robot-compatible torsion applications. Both cable variants can withstand over 10 million bending cycles and over 10 million torsion cycles up to ±180°/m or 5 million up to ±360°/m. An added advantage of the new generation is the reduced cable capacitance. The SABdynamic 900 and 910 data variants achieve very high signal integrity, due to the reduced material thickness of the SABIX-based insulating sleeve. Therefore, they ensure interference-free and loss-free data transmission for real-time applications even with cable lengths over 20 m. The new SABdynamic 900 and 910 cable series, each manufactured in control and data versions, are designed for voltages up to 350 V and 600 V respectively and can withstand temperatures between -40 °C and 90 °C. In addition, they have an excellent TMPU-tested oil resistance according to EN 50363-10-2 and VDE 0207-363-10-2 as well as good chemical resistance to acids, alkalis, solvents and hydraulic fluids. They are UV-resistant according to HD 605, ozone-proof according to DIN EN 50396, saltwater-resistant according to UL 1309 as well as RoHS-compliant and LABS-non-critical. In addition, both versions are PFAS-free, which offers users operational safety even in the event of a PFAS ban. Thanks to the halogen-free material mix with a flame-retardant, self-extinguishing PUR jacket, both product series meet the approval criteria for the North American market. SAB Bröckskes supplies S900 Data by default in the format 12 x 0.14 mm˛ as a multi-core unshielded cable as well as in four multi-pair shielded variants. The S910 Data version is available in three standard versions. SAB Bröckskes offers standard control cables as two multi-core unshielded and two multi-core shielded options. On request, the manufacturer develops and produces bespoke solutions with customer-specific dimensions, different sheath colors and individual cable designs.

SAB Bröckskes designs special sensor cables for environmental monitoring, offering individual requirements engineering with regard to environmental compatibility, ruggedness, weight, insulation and sheath materials. Sensor-based biomarker tracking is gaining importance in environmental monitoring and ranges from long-term air and water quality monitoring to sample evaluation of farm surface water and real-time water level monitoring. The reliability and longevity of the sensor systems are crucial in all monitoring tasks. Wired connections have proven to be a robust and reliable solution. High transmission capacities and data rates can be achieved via USB 3.0 and Gigabit Ethernet, depending on the sensor and measurement task. However, the ecological footprint has a negative impact if critical raw materials are combined or in case of less sustainable manufacturing processes. ‘For this reason, we attach great importance to sustainability in production and material selection,’ says Marc Gerlatzek, Business Development for the Medical Technology and Assembly Division at SAB Bröckskes. ‘For example, the jacket material in our SABorganic series consists of around 45 percent ecological, environmentally friendly raw materials. As a result, we reduce our CO2 footprint by an average of 25 percent compared to comparable fossil products. We source the materials from short, regional supply chains.’ Sustainable, resource-saving production processes are just as relevant for the life cycle assessment. SAB Bröckskes now generates around a quarter of its electricity needs from renewable sources from its own photovoltaics systems.

Deburring glove compartments, laminating interior trim, or welding ventilation pipes—these are just some of the tasks involving plastics processing in modern cars. Heat processes are often required in challenging corners, small spaces or along edges.
Infrared contour emitters are shaped precisely along these contours, which offers decisive advantages. Heat is applied precisely to the burr or fold, minimizing energy consumption and optimizing the production step.
“This automates a complex process with reproducible results,” says application specialist Michael Jauch. “We have customers who have now performed more than half a million deburring cycles with the same set of emitters!”
Excelitas will be presenting Noblelight solutions for plastics processing at the K trade fair in Düsseldorf in October, hall 11 stand D01. Infrared emitters that are precisely tailored to the product and process in terms of shape, voltage, and power, as well as UV technology for curing.

Clean and efficient plastic welding
Complex pipe systems, transport boxes, and storage containers for windshield washer fluid or brake fluid—many plastic products are assembled from several individual parts during the manufacturing process. The type of plastic, shape, wall thickness, and color have a significant influence on the process. It is worth taking a close look at these process parameters before installing a new joining system. Infrared emitters from Excelitas transfer heat without contact and can be used in programmed time cycles.
In most cases, an infrared emitter module moves between two plastic parts and heats the surfaces of both parts. When the specified temperature is reached, the infrared module moves out, the ends of the parts are pressed firmly together and thus welded to each other.
Infrared welding systems offer many advantages over contact plate systems. The welding process is usually faster and also much cleaner, as no plastic sticks to the heating tools.

Faster deburring, reduced scrap
Plastic handles, covers, and panels are often manufactured using injection molding. The formation of sharp burrs, for example at the mold parting line, cannot always be prevented. Removing burrs before further processing or coating can be a real challenge, especially with complexly shaped parts.
Manual deburring with gas flames or special tools does not deliver uniformly reproducible results. Infrared radiation heats plastic parts contact-free and precisely on the surface in a matter of seconds. Shaped emitters direct infrared radiation exactly where it is needed. This is made possible by reflectors that are applied as a coating directly to the shaped emitters. The light emission gap is selected so that the energy arrives precisely at a burr. This enables in-line production of plastic parts and significantly reduces the reject rate in the production of molded parts.

Targeted heating for laminating
Door panels, headliners, and other interior parts of a car are of higher quality when the decorative trim is bonded to the back of the workpiece. This lamination is usually done in a wrapping tool, where the adhesive on the decorative trim is activated by heat. Infrared contour emitters heat the wrapping area precisely, ensuring a very efficient heating process.

Infrared heat for efficient energy use
Infrared heating technology works by transferring electromagnetic waves, which then generate heat in the product. This requires neither direct contact with the material nor a transfer medium such as gas or air. Infrared emitters transfer energy into a plastic product and generate heat exactly where it is needed. This helps to solve many requirements.
Infrared systems with contour emitters can be optimally networked with robots or handling systems. The ability to switch infrared emitters on or off in a matter of seconds means that energy is used efficiently, time is saved, and ultimately production costs are reduced.

Replacing an explosion-proof size 1000 motor at short notice is an ambitious task. For the German family-run company Menzel Elektromotoren, it was a chance to prove once again its extensive expertise in the design, manufacture and certification of explosion-proof motors. A plastics producer had to replace an existing extruder motor with ignition protection type Ex d (flameproof encapsulation) very urgently. Menzel and the client found that a motor with the ignition protection type Ex ec (increased safety) would satisfy the current hazardous zone requirements. The motor manufacturer selected a suitable three-phase squirrel-cage motor from its extensive stock, individually adapting it for the drive task and the installation site. The project hinged on upgrading the motor for zone 2 hazardous areas with potentially explosive gas atmospheres and getting it the necessary ATEX certification. Menzel’s officially certified in-house experts labeled the motor II 3G Ex ec IIC T4 Gc. The new motor with a lower shaft height at 630 mm was brought up to the center height of the old motor by means of a welded base. Since the new motor has four winding systems instead of the two of the old one, Menzel also made electrical modifications for operation on the existing frequency converter. The project exposes the existing supply gap for explosion-proof motors in large sizes: the few existing suppliers can only offer building a motor from scratch – with the corresponding months-long delivery times. Menzel stands out from the competition with its large stock inventory and ability to configure and adapt stock electric motors in-house for hazardous areas and certify them according to the latest ATEX directives. In this instance, only two weeks passed from order placement to installation at the customer’s site. The customer came to Berlin for testing and acceptance and praised Menzel’s flexibility.
