Wear-free decentralised soft starter and reversing starter
Nord Drivesystems is presenting 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, I ²t 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 becomes generally more cost effective, space saving, and faster. 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, which is optionally with plugs.
The soft start function reduces mechanical stress, preventing shocks during start-up and braking. A voltage boost can be programmed for applications requiring high break-away torques. Various braking modes are available. The starter features four potentiometers and four DIP switches for adjusting the most important parameters. LEDs signal the operating status. Parameterisation and diagnosis can be carried out via parameter boxes or via a PC, using the free-of-charge NORD CON software. NORD's entire distributed electronics program, which also includes the SK 180E and SK 200E series frequency inverters, provides the benefit of a uniform operation concept.
