Abstract

The invention provides a motor convenient for fluid flowing. The motor comprises stator windings and ventilation channel steel. According to the technical points, two pieces of rectangular ventilation channel steel are arranged between two adjacent stator windings of one group, one piece of trapezoid ventilation channel steel is arranged between one group of two adjacent stator windings and another adjacent group of two stator windings, and the width radio of the upper half part to the lower half part of the trapezoid ventilation channel steel is 2:1. The ventilation channel steel after changing changes a lot both in shape and distribution, and the lower part of each piece of trapezoid ventilation channel steel is narrowed, so that the flowing range of a fluid is increased, and the flowing speed of the fluid is increased; the eddy current loss is reduced due to the change of the direction of the fluid, and the concave-shaped design of the upper part of the trapezoid ventilation channel steel further increases the flowing speed of the fluid; in addition, the distribution mode of the trapezoid ventilation channel steel and the rectangular ventilation channel steel facilitates the heat exchange between the inner part and the outer part of the motor, the temperature rise of the motor is reduced, and heat loss through convection is facilitated.

Description

Technical field: [0001] The invention belongs to the technical field of motor ventilation, and in particular relates to a motor for facilitating fluid flow. Background technique: [0002] The heat dissipation of traditional medium and high voltage motors is not good, and when each part of the motor fails, it will also cause the heat of the motor to increase, which will bring a greater burden to the cooling system of the motor. The temperature rise of the motor not only determines the safety of the motor operation, but also seriously restricts the increase of the power density of the motor. At the same time, it also has a great impact on the efficiency, output, service life and other performance indicators and economic indicators of the motor. [0003] A rectangular ventilation channel steel is arranged between every two adjacent stator windings of the existing motor. This structure is not conducive to the flow of fluid and affects the overall heat dissipation effect of the m...
