Abstract

The present invention relates to a motor test water cooling and temperature control system, comprising a primary cooling device (1) and a secondary cooling device (2), wherein the primary cooling device (1) cools the secondary cooling device (2), and the secondary cooling device (2) cools a test motor (3), wherein the primary cooling device (1) outputs a cooling medium, which is a coolant, and the secondary cooling device (2) outputs a constant temperature medium, which is any one of a coolant or water. The present invention cools the secondary cooling device (2) by the primary cooling device (1), thereby ensuring good cooling efficiency, thereby accurately controlling the secondary cooling device (2) to output the constant temperature medium, achieving the purpose of temperature control, accurately simulating different temperature conditions, and facilitating the measurement of motor performance at different temperatures.
