TECHNOLOGY n OMRON HAS ANNOUNCED a family of AC drives aimed at the global market that, it claims, set new standards in drive technology. The M1 drives can power a variety of motor types including induction and permanent magnet synchronous motors (including direct-drive types with up to 128 poles), as well as special machines such as drum motors. They can deliver up to 200% torque at 0Hz. The drives are available in ratings from 0.122kW, in 200V single-phase, and 200V or 400V three-phase versions. They can operate in open- or closed-loop vector modes, and can provide speed, torque or precision position control, as well as master-follower functions. The maximum output frequency is 590Hz. The VSDs support Modbus and EtherCat communications and can operate in standard or ring topologies. Encoder and pulse counter inputs are built in, with highspeed position capture via digital inputs for accurate motion control. Motor parameters can be adjusted using the autotuning function in Omron’s Sysmac Studio environment, which provides an intuitive tool for configuring, monitoring and managing systems. There are built-in energysaving functions. The drives offer Safe Stop 0 functions with Safe Torque Off (STO) capabilities that comply with SIL3 / PLe. They support both wired and Fail-Safe over EtherCat (FSoE). Omron is guaranteeing 10 years of maintenance-free operation, even in demanding industrial settings. The dust- and moisture-resistant drives incorporate coated PCBs to enhance durability. Certifications include CE, UKCA, cULus, KC, RCM and RoHS, for compliance with international safety and environmental regulations. https://industrial.omron.eu/en/products/m1 www.rittal.co.uk Omron’s new drives support EtherCat and provide position control via a built-in encoder interface AC drives for global market come with 10-year guarantees THE UK ELECTRICAL TEST and measurement specialist Megger has announced a range of automated static motor analysers that can be used: to assess the health of electric motors; to monitor and analyse trends in motor condition; and to locate faults. Depending on the model, the portable Baker ADX analysers can provide highvoltage tests for surge, turn-to-turn partial discharge, insulation resistance, polarisation index, step voltage tests, as well as lowvoltage tests for winding resistance, inductance and capacitance. The analysers offer a choice of manual, automatic or sequenced testing. They also support configurable route-based site testing and incorporate asset management tools. Test results are displayed on an 10.4-inch touchscreen and are stored on the instrument. The results can be synchronised automatically with the cloudbased PowerDB Dashboard application which provides additional facilities for analysis, reporting and archiving. “Carrying out comprehensive static tests on motors has traditionally involved using multiple instruments, which has made it inconvenient and costly,” explains Megger’s regional sales manager, Mike Herring. “Because of this, tests have rarely been carried out routinely, which means that opportunities to spot and remedy progressive faults on critical motors have been missed. By providing a full range of tests in one fully automatic instrument, the ADX solves this problem, while also offering an invaluable resource for acceptance testing and fault-finding.” https://uk.megger.com Automated motor tester can spot progressive faults
