Starters for synchronous and asynchronous motors

Our program covers three different starter systems for electric motors.

Our electronic soft starter protects your motors and the driven machine by way of a soft acceleration control. It avoids the typical starting problems like high currents and high wear and tear. These products are available for line voltages of 400, 500 and 690V up to 3000A. The soft starters are mounted into the motor feeders. Typical applications are all non speed-controlled drives as conveyors, compressors, coolers and mixers, fans, mills, pumps and centrifuges.

The starting devices with starting transformers for medium voltages up to 13,8 kV are designed according to the three breaker method of Korndorfer. The supply covers a complete unit with transformer, vacuum breakers (star point and bridging contactors) plus protections.

Single line for starting transformers

Our starters will be supplied independently from the manufacturers of motor and switchgear. They can be mounted directly next to the motor or in a switch cabinet. The transformers can be supplied optionally with oil cooling or as dry type. For the dimensioning we need a speed / torque curve, motor starting current at direct on line operation and the WD² values of the drive. If desired, we can dimension economic liquid starters for your plant.
