round up DRIVES + MOTORS + SWITCHGEAR

Reliable operation in the Arctic or the desert

ABM Greiffenberger has added unit sizes 80 and 100 with up to 13 kW of power to its portfolio of energy-efficient SINOCHRON Motors. The system provider introduced the new unit size 80 at LogiMAT 2018. ABM SINOCHRON Motors are char- acterised by high power densities and efficiencies. This is particularly useful in partial-load. The full torque supplied by the motor is solely used for short periods for the initial move of the load. The drives then usually run at 20 to 30 percent of nominal load. This is precisely where ABM SIN- OCHRON Motors show their superiority over standard asynchronous motors. Their efficiency is more than twice as high in the partial-load. This is made possible by a con- tinuously excited synchronous motor which operates with practically no rotor losses. Users in intralogistics facilities expect energy-efficient, powerful drives. The drives must also operate reliably. Thanks to an anisotropic rotor geometry and an opti- mum ratio of inductance values in the longi- tudinal and transverse directions, given an appropriate controller such as the INVEOR drive controller, an ABM SINOCHRON Motor can be operated without the use of speed sensors. Because the rotary encod-

er is omitted, the overall drive runs stably and ensures maximum availability. ABM offers the right controller for every application installed centrally in the electrical cabinet or de-centrally as a mo- tor mounted converter. Application-specif- ic versions round off the portfolio. Through the direct connection of the controller to a 400 V power supply, project planning is simplified and installation requirements minimised. All controllers can optionally be equipped with the corresponding bus systems. Thus, the drives can be net- worked and are suitable for meeting the requirements of Industry 4.0. The drives operate reliably at ambient temperatures from –30°C to +60°C. Thus, they offer users a broad area of applica- tions. Torque fluctuations are minimal thanks to the special rotor design. This provides for very good torque synchro- nisation and a low noise level. ABM has taken various design measures aimed at addressing demagnetisation of the mag- nets to yield an especially high service life and thus high facility availability. Use of a SINOCHRON Motor also usu- ally enables a reduction in unit size. The result is a low-weight drive that can be in-

tegrated easily into the application on ac- count of its compactness. Amortisation is achieved much more quickly due to drasti- cally lowered energy costs. ABM SINOCHRON Motors can be com- bined with all ABM gears (helical, parallel shaft, and angular gears) and are hence the ideal drives for ‘green logistics’. Apart from being used in intralogistics, SINOCHRON Motors are suitable for use as pump and vehicle drives as well as for a multiplicity of further industrial applications. Enquiries: Dagmar Koziel.

Discussing the future of mining

In terms of new products to be displayed, Maleka points to the ECDriveS ® 24 V drive system for light-load conveyor applications. Another materials-handling innovation from SEW to be show- cased is its Automated Guided Vehicle (AGV) system for assembly lines in a range of industrial sectors. AGV systems are used to au- tomate in-house material flows, or they can serve as the basis for flexible assembly operations. SEW’s total AGV system solution covers individual vehicles, energy supply, and the WLAN commu- nication, as well as the navigation and vehicle coordination. The MOVITRANS ® line cable laid in the floor enables contactless ener- gy transfer, making it wear-free and low maintenance. Enquiries: Jana Klut. Email: jklut@sew.co.za

Drive and automation specialist SEW-EURODRIVE South Africa will give insight into the future of mining at Electra Mining Africa 2018 at the Nasrec Expo Centre in Johannesburg from 10 to 14 September, where it will display its total solutions offering for the mining industry. Long-known in the mining industry as a manufac- turer and supplier of geared units, SEW National Sales Manager Norman Maleka highlights that Electra Mining Africa 2018 is the ideal platform to convey the full extent of its services and prod- ucts to as wide an audience as possible. SEW experts will be on-hand to discuss the latest innovations from the company, including Mechatronic Industrial Gear (MIG) units which represent the convergence of gears, motors, and de- centralised inverters in a single handy package. According to Maleka this is an exciting future technology for the mining industry, especially with the increasing trend towards auto- mation. The MIG unit is an innovative solution that ensures practi- cal benefits and profitability across all stages, from the initial inquiry right through to maintenance. “The fact that we are in a position to not only predict what the technology trends in the mining industry will be in the short to long term, but have already developed products to meet such demands, places us in a very good position to keep our customers up to date with the future of mining,” Maleka notes.
