Low-voltage synchronous generators up to 1 000 V for diesel and gas generator sets
Country: USA · Model: LV synchronous generators
Low-voltage brushless synchronous generators for voltage up to 1 000 V for generator sets with a diesel or gas engine. They work in standby and continuous duty and are supplied mainly to generator set manufacturers. The voltage regulators K65-12B, K125-10B, KCR 360 and KCR 760 are selected separately.

Description
The stator is made of a laminated core of electrical steel sheets, held by steel rings and tie bars in a frame with welded feet or base plates for mounting on the set frame. The winding of multilayer insulated copper coils is impregnated with resin by dipping or by the vacuum pressure impregnation (VPI) method. The rotor is salient-pole with a damper winding, the armature of the brushless exciter with a rotating rectifier sits on the shaft, and a permanent magnet pilot exciter (PMG) is added on request. The neutral is not connected to the frame, and earthing terminals are on the feet and in the main terminal box. Insulation is class H with temperature rise per class H, F or B, cooling ODP, CACW or CACA, with sleeve or rolling bearings. On request data are issued for torsional analysis of the shaft line, short-circuit damage and decrement curves, and also reactances and time constants for protection coordination. The line has been developed since the 1920s, when it started with a self-excited 350 W generator for an air-cooled engine, and in 1993 the hundred-thousandth order was shipped.
How to choose
Voltage determines the version. This item covers generators up to 1 000 V, and separate lines exist for medium and high voltage. Then compare the engine speed, the duty (standby or continuous) and the cooling method ODP, CACW or CACA. The regulator is chosen for the excitation type. The K65-12B and K125-10B in a potted plastic case are intended for brushless generators at 50 and 60 Hz, and the KCR 360 and KCR 760, paralleling modules, line drop compensators and protective relays are also offered.
