Summary

• GM generators are new design products basedon the magna plus generators of marathonelectric USA.
• The generators can be coupled with variousinternal combustion engines to form thegen-sets for stationary or mobile powerandsuitable for primary and standby power.
• The generators are not only unique designedwith top performancesbut also reliable andconvenient.the generators may be usedindifferent application and varying whethercondition asits excellent product features

Outstanding Electric Characteristics

• Steady voltage regulationis less than 1%.
• Transient voltage regulationis lessthan
  +20%，-15%(60%In. P.F ≤ 0.4 LAG).
• Voltage adjusting rangeis is ≥ c5%Un OR UN.
• Total voltage waveform distortionis is ＜ c5%(L-L).
• Thermal warp: approximately zero.

Unique Structure

• Full guarded for operator safety. the unitshave a unique ventilation and structure with efficient heat transfer and cooling.
• Brushless excitation with solid-state circuitavr，( se 350)which is encapsulation formoisture with vibration protection.
• Unirotor construction with full dampingwinding(die cast]，field windings are layerwound with thermo – setting epoxy formechanical and electricalintegrity
• Stator winding of 2/3 pichminimize harmonicdistortion.
• H classinsulationsystem
• Double shielded & pre-lubricated bearing forhigh life(b10，220000 hours).
• Rectifier assy.located outboard of theexciter for easy service.
• Conduit boxis mounted on the top of framethe accessaries can beinstalledin the amplebox.
• Paralleling module & accessaries can beassembled as customer requested
• Pmg&dvr2000e can be assembled as customersrequest.
• Heater and thermal protection element canbe assembled as customers request.
• Leads and 8 poles linkboard. 12 leads as option.
• Standard sae adaption

Operating Condition

• Ambient temperatures ≤ 40℃
• Altitudes ≤ 1000M.
• Note: if the environment conditionis higheror different from above requirements,the output power should refer to corresponding decreated table
