Motor reactors reduce the voltage stress on the motor windings by reducing the voltage gradients at the motor terminals that occur when motors are fed from drive converters. At the same time, the capacitive charge/discharge currents that occur at the converter output when long motor cables are used are reduced. Suitably dimensioned motor reactors therefore enable large capacitances and thus longer motor cables to be connected. Their use is generally recommended in the case of multi-motor drives. With option L08 for Motor Modules, a motor reactor is integrated into the Motor Module up to cabinet size GX (outputs of less than 315 kW). Due to space constraints, a separate cabinet must be planned for the output range 315 to 450 kW (cabinet size HX).
