Definitions
- the invention relates to a temperature measuring device for measuring the temperature on a component of an electric motor provided with windings.
- thermocouples For temperature measurement, it is known to attach a thermocouple as a thermal sensor in the area of the windings. Due to the strong insulation, however, thermocouples are relatively slow and the positioning of thermocouples with selective measurement is not optimally reproducible, which can lead to a measurement error of + 10 ° C.
- the invention has for its object to provide a temperature measurement device for electric motors that can be used easily and provides accurate and reliable results. Furthermore, a method for temperature measurement is to be specified.
- the measuring element made of a material with temperature-dependent material properties, the measuring element extending over a section along at least one winding and changes in the material properties being detected via a detector device.
- the measuring element can be designed, for example, as a rod, the temperature-dependent change in length of which can be detected by suitable distance sensors acting on one or both ends of the rod. Basically, this can also be done optically.
- the measuring element is designed as a rod or as a glass or plastic fiber and can be used, for example, as a light guide.
- the measuring element is preferably formed from a uniform material in the region of the section.
- the measuring element runs over a section of at least one winding, the material of the measuring element heats up in this section, so that the temperature-dependent material property changes accordingly and the temperature can be inferred from this change.
- an additional line made of uniform, electrically conductive material can be used as the measuring element, which runs over a section along at least one winding and the ends of which are led to the outside of the motor.
- the electrical properties, in particular the temperature dependence of the resistance, of a known material are generally known or can be measured in a simple manner. Since, according to the invention, the additional line runs over a section of at least one winding, the material of the additional line heats up in this section, so that the resistance changes accordingly and the temperature can be inferred from this change.
- the measuring element or the additional line can be placed on a winding or, preferably, embedded in a winding so that the temperature inside the winding can be determined.
- the additional line is preferably designed as an insulated single wire.
- the section of the measuring element is also arranged in this area, in particular in such a way that the section covers the entire area of the winding which lies within the winding core , wherein the section can be divided into several sections.
- the additional line can be designed as an insulated double line with a short-circuited end; it is also possible to wind the additional line as a coil in the area of the winding.
- the measuring element can in particular be easily integrated into the winding structure if the diameter of the measuring element is approximately as large as the diameter of the winding wires forming the windings.
- the temperature measuring device and the method according to the invention are suitable both for rotary electric motors and for linear electric motors.
- Fig. 1 is a schematic end view of a primary part of a linear motor
- FIG. 2 is a top view, partially broken away, of the primary part of FIG. 1.
- the primary part of a linear motor shown in the figures basically has a conventional structure consisting of a winding core 10 with winding teeth 12 to which windings 20 are applied. Since the further construction of a primary part of a linear motor is known, an explanation is omitted here.
- the primary part according to the invention comprises at least one additional line 30 with a section which is embedded in at least one winding.
- the line 30 comprises two sections 32 and 36, which are embedded in the form of an insulated double line with an insulated short-circuited end 34 in the coils such that they cover essentially the entire area of the coils or windings 20 between the winding teeth 12.
- the sections 32 and 36 are connected to one another via a bridge 38.
- the connections of the additional line 30 are led out of the primary part and can be connected outside with the necessary electrical circuits for measuring the resistance.
- three additional lines 30 are shown, each of which is assigned to a coil 20. These three additional lines can be operated separately for temperature measurement in the individual windings, so that each phase, U, V, W can be regulated individually when operating with three-phase alternating current.
- the electrical resistance of the additional line 30 is measured by suitable methods, which are generally known and therefore not explained in detail, and compared with resistance values which are calculated from the dimensions of the lines and the temperature-dependent material properties and / or are determined by calibrating the additional line. Any electrically conductive materials with a suitable temperature dependence can be used as materials for the additional lines.
- the conductors of the additional lines should at least in the region of the section on the windings consist of a "uniform" material, ie of a single material. This avoids voltage effects at contact points and the determination of the resistance value is simplified.
- the coils or windings 20 themselves to determine the temperature. Since material properties are also temperature-dependent here, measurement of electrical variables can be used to draw conclusions about the resistance or changes in resistance. Such measurements can be carried out, for example, with a single coil or with all coils belonging to a phase by suitable calibration of the primary part, for example by recording resistance values depending on a set temperature, a table for determining the resistance values and thus the temperature values can be created.
