Abstract
The invention discloses a totally-enclosed oil-cooled permanent magnet generator. A prime mover power interface drives the generator to rotate at a high speed, magnetic fields generated by permanent magnets on a stator winding and a rotor are rotationally cut to generate an electric potential, and the voltage of the generator rises along with the increasing of the rotating speed of the generator. When the increased rotating speed approaches a rated rotating speed, the voltage of the generator stabilized to a required voltage value. The generator is connected with an inverter, and the required power supply is output by the suitable inverter. An opening of an inner cavity of a stator housing is utilized, and the rear end surface of the opening of the inner cavity of the stator housing is provided with an installation rabbet of a rear end cover, the opening of the inner cavity is connected with the rear end cover to form a heat dissipation oil channel, and flowing cooling engine oils cools a motor stator. The generator structure with a novel cooling mode is provided by the invention and solves the problem that a conventional air-cooled generator structure is heavy or a water-cooled generator structure is relatively poor in stability.
Description
Technical field
The present invention relates to a kind of permanent magnet generator, be specifically related to a kind of totally-enclosed oil cooling permanent magnet generator.
Background technology
Mute generator group is often installed in small space, very high to generator unit structure dimensional requirement.Tradition Wind-cooling type generator needs special heat dissipation wind channel, and physical dimension can not meet requirement; Water-cooling type generator, because of too fast to generator frame cooling rate, easily cause generator unit stator material deformation, even ftractures, and also can affect sealing between bore of stator and heat radiation road for a long time.
For solving the problem, summing up a kind of totally-enclosed oil cooling permanent magnet generator, by generator unit stator housing cavity design heat radiation oil duct, utilizing the cooling machine oil of flowing to dispel the heat to generator unit stator.The relative water cooling weak effect of cooling machine oil radiating effect some, but very little on the impact of generator workpiece, and corrosion phenomenon can not be caused to workpiece for a long time.
Summary of the invention
The object of the present invention is to provide a kind of totally-enclosed oil cooling permanent magnet generator, solve a difficult problem for traditional Wind-cooling type electric generator structure heaviness or water-cooling type electric generator structure less stable.
Patent of the present invention is achieved like this, and a kind of totally-enclosed oil cooling permanent magnet generator, mainly comprises prime mover power interface, engine rotor housing, permanent magnet, stator combination, stator case, oil inlet pipe, cooling machine oil, oil radiator and oil return pipe; It is characterized in that: permanent magnet is inlaid on rotor case, rotor case is bolted on prime mover flywheel, forms a rotation combination; Stator combination (stator core of band winding) is bolted on stator case, and stator case is bolted on prime mover bell housing again, forms a fixed Combination; Under operating state, chemical energy (bavin Water Oil Or Gas) is converted into mechanical energy (prime mover flywheel High Rotation Speed) by prime mover, thus the permanent magnet on rotor driven housing rotates, the magnetic line of force that the winding cutting permanent magnet in stator combination produces, and finally produces electromotive force.The seal chamber of splendid attire cooling machine oil is designed with in stator case, cavity upper and lower is respectively equipped with oil inlet pipe, oil return pipe, be provided with oil radiator between oil inlet pipe and oil return pipe, electronic oil pump guarantee of work machine oil circulates between stator case and oil radiator, and distribute heat.
Oil radiator having electronic oil pump of the present invention.
Prime mover power interface drive electrical generators High Rotation Speed of the present invention, the magnetic field that stator winding and epitrochanterian permanent magnet produce is carried out circumgyration incision and is produced electromotive force, and along with generator speed raises, generator voltage also raises.When rotating speed is elevated to close to rated speed, generator voltage is stabilized on required magnitude of voltage.Generator is connected with inverter, the power supply required for being exported by suitable inverter.Utilize stator case lumen openings, the installation seam of face design back lid, is connected to form heat radiation oil duct with rear end cap in its back-end, and the cooling machine oil of flowing dispels the heat to motor stator.
Generator unit stator of the present invention High Rotation Speed relative to rotor, produce electromotive force, High Rotation Speed makes generator unit stator temperature very high, stator case lumen openings is utilized to design heat radiation oil duct, the electronic oil pump of oil radiator drive cooling machine oil pass through into, return machine oil pipe and flow fast between generator and oil radiator, motor stator is dispelled the heat.
Advantage of the present invention is: described totally-enclosed oil cooling permanent magnet generator is mainly used in place generator size and weight being had to strict demand, especially with the generating equipment that oil cooling type prime mover is supporting.Generator is dispelled the heat to body by machine oil, does not need heat dissipation wind channel and the radiator fan of conventional electric generators, and structure is simple, easily and prime mover is supporting is arranged in less casing.Machine oil cooling rate is slower than water, can not suddenly cold and hot, and overall structure stability is more superior than water-cooling type generator, and machine oil can not corrode generator unit stator workpiece for a long time in addition, and lubricates some parts of generator by appropriate design.Solve a difficult problem for traditional Wind-cooling type electric generator structure heaviness or water-cooling type electric generator structure less stable.
