Abstract
The utility model discloses a water-cooled motor. The water-cooled motor comprises a casing, a stator and a rotor, wherein the stator is mounted in the casing, a gap is kept between the stator and the casing, the gap is provided with a water-cooled device, two ends of the casing are provided with end covers, central portions of the end covers are provided with shaft holes used for erecting the rotor, the rotor is rotatably arranged in the stator through the shaft holes, and the end covers are internally provided with cooling fans which are in fixed connection with the rotor. Through the water-cooled device, heat in the stator can be dissipated fast, so temperature in the motor can be effectively reduced, and thereby a fault of the motor caused by over-high temperature of an inner portion of the motor can be avoided.
Description
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of water cooled machine.
Background technology
Motor is the instrument that electric energy is transformed into mechanical energy, and its composition generally comprises stator, rotor and end cap.Wherein comprise stator core and rotor core in stator and the rotor, along with the development of society and the enhancing of industrial technology, people further strengthen the requirement of motor power output, and this has just promoted the appearance of heavy-duty motor.The power of motor is more big, its stator and rotor core also just inevitably need to increase, motor is in the middle of the process of running, owing in the winding passing through of electric current arranged, on the lead of motor winding, can produce Joule heat, like this, in the middle of the process of motor rotation, need to have a large amount of caloric requirements to discharge, for low power motor, because the length of its stator core and rotor core is less, thereby in the middle of the process of running, can satisfy the cooling requirement of motor by the flabellum with the main shaft rotation that is loaded on the bottom, but along with the disconnected increase of motor power output, the stator core of motor and the length of rotor core is also in continuous increase, therefore only relies on the flabellum of motor bottom of the prior art can not satisfy the demand of motor radiating.
Discover that the internal temperature rise of motor is more little, the maximum power of its output and the difference of rated power are also just more little, the probability that motor breaks down is just more little, in view of this, still be for the low-power machine for heavy-duty motor no matter, the cooling of motor internal is vital.
In view of this, motor internal is better cooled off, improve its peak power output, reduce its probability of failure, be the technical problem that those skilled in the art need solve.
