Embodiment Construction

[0037] based on Figure 1 to Figure 3 For motor 2 with electronic thermal relay (see Figure 4 ), an example of a processing device that performs adjustment of model parameters for estimating the temperature of the motor winding by the electronic thermal relay will be described. In addition, in the embodiment of the present disclosure, the motor 2 only needs to have a structure in which the stator is wound with windings and has a rotor, and the specific structure thereof is not limited to a specific structure. In addition, inside the motor 2, a temperature sensor 3 is arranged so as to detect the temperature of the winding. More specifically, the detection portion of the temperature sensor 3 is located in the vicinity of the winding, and the detection portion is preferably in contact with the winding. A temperature sensor 3 is arranged in this manner.

[0038] here, figure 1 The schematic configuration of the calculation model 10 for calculating the winding temperature incl...

Abstract

The processing device acquires a first rising shift as a rising shift of the temperature of the winding and a second rising shift as a rising shift of the temperature detected by the temperature sensor in a state in which a voltage for rising the temperature of the winding to a predetermined temperature is applied, and acquires a second rising shift as a rising shift of the temperature detected by the temperature sensor based on the second rising shift. A predetermined parameter is calculated to determine a predetermined temperature characteristic model, and a winding-related parameter is calculated to determine a winding temperature characteristic model on the basis of the first rise transition.

Description

technical field [0001] The present invention relates to techniques for performing adjustment of model parameters related to electronic thermals of motors. Background technique [0002] Motors are used in various fields, and rotational speeds, motor loads, and the like that are conditions of use are also various. In addition, the surrounding atmosphere of the motor is not necessarily constant, and generally, when the surrounding temperature of the motor becomes high, it becomes difficult to dissipate heat from the motor, and the use environment becomes severe. When driving a motor, if it is placed in an overloaded environment, the temperature of the winding of the motor may rise excessively, and the winding may burn out. In order to avoid such burnout of the winding, there is a technique in which a temperature sensor such as a thermistor and a thermostat is embedded in the motor, and the temperature of the winding is directly detected by these to avoid overload operation of ...
