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...

Abstract

The present invention discloses a motor cooling structure for cooling a motor including a stator including an iron core wound with coils, a permanent magnet rotating with an electromagnetic field generated by the coils, and a rotor including a rotating shaft, and for cooling a motor for controlling the The motor cooling structure of the inverter of the motor includes: an integrated motor housing for accommodating the motor and the inverter; a cooling water channel formed along the outer periphery of the motor housing for cooling the Cooling water for the motor and the inverter flows; and a cable housing portion formed outside the motor case to accommodate a control cable connecting the motor and the inverter. According to the motor cooling structure of the present invention, the motor housing and the inverter housing can be integrated to improve the efficiency of the assembly space, and a storage space for accommodating high-voltage control cables is formed in one housing to easily shield electromagnetic waves.

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...
