NORD Drivesystems presents a new range of motor-mounted starters offering an extended performance range for the distributed implementation of soft start and reversing functions in 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, I²t monitoring, and magnetising current monitoring. The electronic, wear-free switching technology replaces motor circuit breakers, reversing contactors and brake rectifiers, rendering entire control cabinets unnecessary in large facilities. 

Installation becomes more cost-effective, space-saving and faster as PTC thermistor connection cables and brake control cables are not required. 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 available 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 breakaway torques. Various braking modes are also available. 

NORD’s new starter features four potentiometers and four DIP switches for adjusting the most important parameters. Parameterization and diagnosis can be carried out via parameter boxes or 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.
