Abstract
Disclosed in the utility model is a motor suitable for multiple cooling modes. The motor includes a casing, a stator iron core, a rotor iron core, and a rotating shaft; and the rotor iron core is coaxially and fixedly arranged at the rotating shaft. The motor is characterized in that a cooling tube that is bent back and forth towards the axial direction is arranged at the external circular surface of the stator iron core; a liquid inlet and a liquid outlet are arranged on the cooling tube, wherein the liquid inlet and the liquid outlet pass through the casing; a radiating fin covers the cooling tube and is fixedly arranged at the external circular surface of the stator iron core; and a circulating ventilation mechanism is arranged between the radiating fin and the rotor iron core. The advantages of the motor are as follows: because the cooling tube and the radiating fin are installed on the external circular surface of the stator iron core, the heat of the stator iron core can be directly absorbed without the need of casing transmission, so that the heat transmission path is short and the heat dissipation efficiency is high; and due to the circulating ventilation mechanism arranged between the radiating fin and the rotor iron core, the heat radiation area of the radiating fin is increased and thus the heat radiation efficiency of the air cooling loop is improved, so that the temperature rising of the rotor iron core, the bearing and the stator iron core are basically consistent.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of motor that is suitable for the multiple type of cooling.
Background technology
The power of large and middle size motor is big, caloric value is big, if heat radiation is insufficient, then easily causes the motor internal temperature rise too high, has a strong impact on motor properties and useful life.Existing large and middle size motor great majority adopt the water-cooling method that processes helicla flute or axial baffling groove structure in casing.This method is better near the cooling effect of the stator the cooling bath, but bad away from the cooling effect of the rotor portion of cooling bath, causes the temperature rise of rotor and bearing higher.
In order to overcome the deficiency of water cooling mode, the method for a small amount of employing air and water cooling combination is also arranged at present.This method is that cooling water channel is set in casing, and leaves air duct on cooling water channel, and the air in the motor circulates by air duct, and the heat of rotor can be taken heat out of motor by cooling water channel again by transfer of air to cooling water channel.Though this method has all played cooling effect preferably to stator and rotor, the complex structure of casing, the processing cost height, in addition since between cooling water channel and the stator core across certain thickness enclosure wall, influenced radiating effect to a certain extent.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of good heat dissipation effect, and the motor of the suitable multiple type of cooling simple in structure.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of motor that is suitable for the multiple type of cooling, comprise casing, stator core, rotor core and rotating shaft, described rotor core is coaxial to be fixedly installed in the described rotating shaft, the periphery of described stator core is provided with and is axially the cooling water pipe of bending back and forth, described cooling water pipe is provided with inlet and the liquid outlet that passes described casing, be coated with fin on the described cooling water pipe, described fin is fixedly installed on the outer round surface of described stator core, is provided with circulating ventilation mechanism between described fin and the described rotor core.
