[NORD Drivesystems] introduces new motor-mounted starter with wear-free switching technology

摘要

NORD Drivesystems presents a new motor-mounted starter with an extended performance range for the economic distributed implementation of soft start and reversing functions, for motors from 0.25 to 7.5 kW. The compact SK 135E integrates motor overload protection through PTC thermistor monitoring, mains and motor phase failure monitoring, Ft monitoring, and magnetising current monitoring. The electronic, wear-free switching technology replaces motor circuit breakers, reversing contactors and brake rectifiers, thus rendering entire control cabinets unnecessary in large facilities. As PTC thermistor connection cables and brake control cables are not required, either, installation generally becomes quicker, more cost-effective, and saves space. When the drives are ordered complete and wired with gearbox, motor and starter, any assembly effort is reduced to simply tightening the screws and establishing the electrical connection, with plugs as optional.
