Embodiment Construction
[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] see figure 1 , which is a structural schematic diagram of a motor cooling cycle system. In actual operation, the cooling cycle system is operated by a water pump 12 to circulate the cooling water in the system. Among them, the motor 10 and the motor controller 11 are mainly used for cooling and heat dissipation. The radiator 13 is used to dissipate heat from the water output ...

The invention provides a cooling control method and device for a motor and its controller. The method includes first obtaining the following parameters: the real-time rotational speed, power and stator temperature of the motor; the temperature of the coolant at the inlet of the motor; the real-time power and temperature of the motor controller; The time the fan is running at its highest gear. Secondly, the flow demand is calculated from the motor speed, power and water temperature, and the flow demand is corrected according to the stator temperature; the flow demand is calculated from the motor controller power and water temperature, and the flow demand is corrected according to the motor controller temperature; take the higher of the above two correction values The larger one is the target traffic demand. Then, the target flow demand is corrected based on the fan running time at the highest gear. Finally, according to the relationship between the pump speed and the flow rate, adjust the water pump to the corresponding speed. The invention dynamically adjusts the speed of the water pump according to the speed and power of the motor, the power of the motor controller and the water temperature, which is more accurate and energy-saving.
Description
technical field [0001] The invention relates to the technical field of cooling, in particular to a cooling control method and device for a motor and a controller thereof. Background technique [0002] The cooling of the motor and its controller refers to the heat generated due to internal loss during operation. The cooling medium cools the motor windings, iron core and power components in the controller to maintain the temperature of each part within the allowable range. Usually, the cooling of the motor and its controller has the following requirements: first, the temperature of the water inlet of the motor and its controller must be less than 65°C; second, the water flow of the motor and its controller must be within the range of 8-12L / min. [0003] At present, the usual control method for cooling the motor and its controller is as follows: firstly, adjust the speed of the water pump so that the flow rate is at a certain value between 8 and 12L / min; secondly, check whether...
