Motor-independent cooling loop system and manufacturing method

Abstract

The invention discloses a motor-independent cooling loop system and a manufacturing method. The system comprises a servo motor and a cooling loop system; multiple cooling runners are arranged in a motor shell of the servo motor, the cooling runners are connected with an oil inlet and an oil outlet; the cooling loop system comprises a first cooling pipeline, a second cooling pipeline, a first checkvalve, a second check valve, a cooling medium storage tank, a cooling water tank and a fan; the first check valve is arranged on the first cooling pipeline, the second check valve is arranged on thesecond cooling pipeline, the cooling medium storage tank, the first cooling pipeline, the oil inlet of the motor shell, the cooling runners of the motor shell, the oil outlet of the motor shell and the second cooling pipeline are orderly connected end-to-end so as to form a vacuum sealed cycle channel. The system disclosed by the invention adopts the principle of reducing the boiling point of theliquid-state cooling medium in vacuum, is simple in structure, small in space size and low in production cost; a set of cooling loop system can be suitable for the servo motors in different specifications and oil inlet and oil outlet sizes, and the universality is strong.

Description

technical field [0001] The invention belongs to the field of motor equipment technology and manufacturing, and in particular relates to a motor independent cooling circuit system and a manufacturing method. Background technique [0002] The temperature and temperature rise of the stator and rotor when the servo motor is working are the main indicators for measuring the performance of the motor. The design and development of the motor cooling system is not only the core technology of motor development, but also a key factor affecting the manufacturing cost of the motor, and ultimately determines the competitiveness of the motor in the economic market. Due to the low temperature of the stator and rotor and the low temperature rise of the liquid cooling system motor, its application and development range will continue to expand. [0003] At present, the liquid cooling system motor is divided into a combined cooling circuit system and an independent cooling circuit system. The...

Problems solved by technology

The combined cooling circuit system is difficult to achieve good compatibility due to the huge system and complicated structural design, and the different cooling requirements of each component

Although the general independent cooling circuit system is relatively simple, the structure is not complicated, and the cooling effect is good; but due to factors such as limited equipment space and high cost, the application development speed is slow
