ST Series Single-Phase Brush Alternator Generator Head 3-24 kW - 100% Copper Winding, 4-Pole, 1500 rpm

The ST series is the classic single-phase brush alternator generator head built by XBY (Fuan City, Fujian) - China's centre of small-alternator manufacturing. Supplied here in the 100% copper-wound specification, it is a straightforward, field-serviceable replacement head for single-phase generating sets and mobile light towers driven by a suitable prime mover at 1500 rpm (50 Hz) or 1800 rpm (60 Hz). This class of machine is a cost-effective Chinese alternative to Western single-phase alternators such as the Leroy-Somer LSA 37 M7 used on Kubota-powered light towers. It is not a like-for-like bolt-on: shaft, flange, coupling and wiring must be verified before ordering, and the ST uses brush/harmonic excitation rather than the original's capacitor excitation. Where an exact match matters, send us the nameplate details and photographs of the outgoing unit and we will confirm the correct frame and winding with the factory. KEY FEATURES - 100% copper winding on the specification supplied through this listing (the factory also offers aluminium-wound versions - we do not sell these) - Single-phase AC output, 230 V series / 115 V parallel connection, power factor 1.0 - 4-pole, 1500 rpm (50 Hz) or 1800 rpm (60 Hz) - suits belt or direct coupling, clockwise or anticlockwise rotation - Harmonic excitation with rotary field - self-regulating, no AVR to fail, steady-state voltage within +/-5% - Drip-proof, fan-cooled IP23-class enclosure for town, countryside, work-site and pasture use - OEM service offered - custom nameplates, voltages and frequencies available from 10,000 sets/year production capacity - Export packing in non-fumigation plywood cases TECHNICAL SPECIFICATIONS Model range: ST-3 to ST-24 (single-phase); STC-3 to STC-75 (three-phase, see options) Output power: 3-24 kW single-phase / 3-75 kW three-phase Voltage: 230/115 V single-phase (series/parallel); 400/230 V three-phase Frequency: 50 Hz or 60 Hz Speed: 1500 rpm (50 Hz) / 1800 rpm (60 Hz) Poles: 4 Power factor: 1.0 single-phase / 0.8 lag three-phase Excitation: Harmonic (rotary field, brush type) Voltage regulation: Within +/-5% Cooling: Fan cooling, drip-proof; cooling air -15 to +40 deg C, altitude <=1000 m, humidity <=90% Windings: 100% copper wire (specification supplied) Bearing: Single bearing, continuous duty Brand / origin: XBY (OEM available), Fuan City, Fujian, China - HS 85016100 Warranty: Manufacturer's warranty - term confirmed with the supplier at order WEIGHT & DIMENSIONS Export packing: non-fumigation plywood case. The supplier's family packaging data for this series lists a case of approximately 710 x 430 x 610 mm with a gross weight of about 240 kg for the larger STC frames; the smaller ST single-phase models ship in correspondingly lighter cases (crate figures for the ST-7.5 class are confirmed per rating at quotation). If you need exact shipping weight and crate dimensions for a specific model before ordering, ask and we will obtain the factory's packing sheet for that frame.
