Embodiment Construction
[0030] The motor cooling structure of the preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0031] like figure 1 As shown, the motor cooling structure 110 provided by the preferred embodiment of the present invention can be installed on the motor 10 composed of the rotor 11 and the stator 12 .
[0032] The motor 10 generates an electromagnetic field using an external power source for generating rotational driving force, and includes a rotor 11 mounted with a permanent magnet 11c reacting to the electromagnetic field and a stator 12 for driving the rotor 11 to generate an electromagnetic field.
[0033] The rotor 11 may include a rotor case composed of a cylindrical support 11b that joins two bottom plates arranged in parallel to each other, and one or more permanent magnets 11c embedded in the bottom plate 11a of the rotor case.
[0034] The rotor 11 has a rotating shaft 11d that transmits a rotati...

The invention discloses a motor cooling structure used for cooling a stator provided with an iron core having a coil, a permanent magnet using the coil to generate the rotating electromagnetic field, a motor provided with a rotor having a rotary shaft, and an inverter of the motor. The motor cooling structure comprises an integrated motor housing used for accommodating the motor and the inverter; a cooling waterway part, which is formed along the periphery of the motor housing, and is used for cooling the motor and controlling the flowing of the cooling water of the inverter; and a cable accommodation part, which is disposed on the outer side of the motor housing to form a control cable connected with the motor and the housing. According to the motor cooling structure, the motor housing and the inverter housing can be integrated together to improve the efficiency of the assembly space, and the accommodation space used for accommodating the high voltage control cable can be disposed in the housing, and the electromagnetic waves can be easily shielded.
Description
technical field [0001] The invention relates to a motor cooling structure, in particular to a motor cooling structure capable of cooling motors mounted on vehicles such as electric vehicles by means of water cooling. Background technique [0002] Currently, research and development activities are active on hybrid vehicles or electric vehicles, which are another form of vehicles that are environmentally friendly and consider fuel efficiency, which are further developed from vehicles using combustion engines. [0003] A hybrid vehicle combines the existing engine with an electric motor driven by electric energy, and drives the vehicle with two power sources. Electric vehicles are only driven by electric motors to reduce environmental pollution caused by exhaust gas and improve fuel efficiency. It is popular in the United States and Japan, and it is gradually attracting people's attention as a second-generation car that solves practical problems. [0004] The hybrid electric v...
