The model utility content
At the prior art above shortcomings, the purpose of this utility model provides a kind of contravariant AC permanent-magnetic generator group, and its topology layout can well solve the torsional vibration and the heat radiation cooling problem of generator set.
The technical solution of the utility model is achieved in that a kind of contravariant permanent magnet generator unit, comprise internal-combustion engine, bent axle, flywheel, generator unit stator, generator amature, hand pulling starter, cooling fan, inverter controller and silencing apparatus, generator unit stator is fixedly mounted on the internal combustion (IC) engine airframe and is positioned at generator amature, flywheel and generator amature are fixedly mounted on the bent axle, it is characterized in that, described flywheel and generator amature are installed in the two ends of bent axle respectively, cooling fan is made of oily machine cooling fan and motor cooling fan, oil machine cooling fan, the motor cooling fan is the opposite centrifugal fan of blade rotation direction, oil machine cooling fan and motor cooling fan are installed in the flywheel and the generator amature outside respectively, and hand pulling starter and flywheel are positioned at bent axle one end jointly.
The utility model also comprise be installed on the internal-combustion engine casing, oily machine fan housing and generator fan housing that its front is equipped with intake grill, hand pulling starter, oily machine cooling fan and flywheel are positioned at oily machine fan housing, and motor cooling fan and generator amature are positioned at the generator fan housing.Inverter controller and silencing apparatus are positioned at generator fan housing bi-side, and the position that the generator fan housing is corresponding with inverter controller and silencing apparatus has some heat transmission air guide holes.
Because oily machine cooling fan and flywheel are positioned at bent axle one end, motor cooling fan and generator amature are positioned at the bent axle the other end, make the crankshaft structure balanced, symmetrical, the torsional vibration that has alleviated bent axle greatly, and internal combustion engine operation is steady, and output power is stable.Cooling fan is divided into two simultaneously, divides position and crankshaft two end, when keeping balance, has also improved the cooling heat dissipation effect greatly.The motor cooling fan also provides cooling air for inverter controller, silencing apparatus except cooling motor.
