Starting and generating integrated switch magnetic flux motor for automobile

Abstract

A starting and generating integrated switch magnetic flux motor for an automobile comprises a stator assembly. The stator assembly is fixed on an outer shell through anaerobic adhesive. A rotor is fixed on a gear shaft of the motor through front and rear sleeves and a flat key. An air gap is reserved between the stator assembly and the rotor. The two ends of the gear shaft of the motor are supported on end caps through bearings. The side, close to the stator and rotor, of the front end cap is provided with an oil seat for preventing lubricating oil of gears and bearings from polluting the stator and rotor. The front and rear end caps and a planetary reducer assembly are fixed on the outer shell through tensioning bolts. A rotary transformer assembly is fixed in the rear end of the gear shaft of the motor. An output gear shaft is engaged with an engine flywheel tooth ring and outputs power to an engine crankshaft when an engine needs to start, and the inputted power is converted into electric energy to charge a storage battery when the engine runs normally. The starting and generating integrated switch magnetic flux motor is simple and compact in structure and low in production cost, and satisfies starting and generating function requirements of the automobile.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a switched magnetic flux motor integrated with starter and power generation for automobiles. Background technique [0002] According to the "China Automobile Society Development Report 2012-2013" released by the Chinese Academy of Social Sciences, the number of civilian vehicles in my country reached 120.89 million at the end of 2012, and the number of vehicles per 100 households will reach or approach 60 in the next 10 years. The total inventory will exceed 200 million vehicles. The huge number of cars will cause urban traffic congestion to spread from big cities to small and medium-sized cities. Under urban conditions, cars need to start and stop frequently, and the engine is often in an idle state. Studies have shown that the energy utilization rate of the engine at idle speed is only about 10% of the normal operation, resulting in a large waste of energy; at the same time, ...

AI Technical Summary

Problems solved by technology

[0005] A switched-flux motor with integrated starter and power generation for automobiles, which overcomes the shortcomings of the current ISG motor's permanent magnets on the rotor with a large moment of inertia. The permanent magnets are directly arranged on the stator, and the rotor structure is simple and the moment of inertia is small.
