Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings, as shown in the figure: a motor cooling system with encapsulated end turns in this embodiment includes a rectangular motor housing 1, spanning the length of the rectangular motor housing 1 The stator cooling water pump 2 at one end of the direction and the stator cooling water pump driving device for driving the stator cooling water pump 2 to move from one end of the motor housing 1 to the other end and simultaneously rotate around the axis of the stator cooling water pump 2 itself. In this embodiment, the stator cooling water pump The water pump 2 adopts the flat stator cooling water pump in the middle. Of course, as long as the stator cooling water pump of circular or other shapes can be installed on the motor, the purpose of the present invention can be achieved. The height of the initial section of the moving route of the stator cooling water pump gradually rises. W...

The invention discloses an electric motor cooling system with packaged end part wire turns. The electric motor cooling system comprises an electric motor shell, a stator cooling water pump transversely crossing one end of the electric motor shell, and a stator cooling water pump pushing apparatus used for driving the stator cooling water pump to move from one end of the electric motor shell to the other end and rotating around the axial line of the stator cooling water pump at the same time; the heights of the starting sections of the moving route of the stator cooling water pump are raised gradually; when the stator cooling water pump is in the starting position, the middle of the stator cooling water pump is connected with the stator in the electric motor shell; when the electric motor cooling system is in use, the electric motor shell is fixedly mounted at first; the stator cooling water pump in the starting position is mounted in the electric motor, so that the water pump can automatically put cooling water in the stator cooling water pump; the stator cooling water pump pushing apparatus pushes the stator cooling water pump to cool the electric motor and to perform water circulation as well; and in addition, due to the good cooling effect, the service life of the cooled electric motor is greatly prolonged, and the problems of damage caused by overheat and the like do not occur frequently.
Description
technical field [0001] The present invention relates to electric motor cooling apparatus and more particularly to an electric motor cooling system with encapsulated end turns. Background technique [0002] The motor cooling system is the main heat exchange part of the motor and an important product to maintain the operation of the motor. It directly affects the temperature rise, output and life of the motor. All turbo generators, hydro generators, and AC and DC motors must use motors cooler. [0003] The traditional motor cooling system is completely dependent on the fan. When cooling, the motor needs to be injected with cooling water first. The surface of the motor is covered with a cold water pipe, and then the stator cooling water pump of the water pump injects cooling water into the stator cooling water pump to continuously circulate the stator. The cooling water pump will eventually reduce the temperature of the motor. This method has the following disadvantages: 1) Th...
