Definitions
- the invention relates to a method and a system for monitoring at least the motor temperature as motor parameters when operating at least one electric motor on power electronics.
- a disadvantage of these methods is that the evaluations only consider the engine temperatures as such. Furthermore, there is a reduced functional reliability, since the motor is only switched off in the event of a thermal overload due to incorrect parameterization of operating points that is not suitable for the corresponding motor or in any case not optimal. In addition, incorrect parameterization of operating characteristics of the electric motor in the event of a malfunction or damage results in increased effort in fault finding.
- a method for monitoring at least the motor temperature as a motor parameter when operating at least one electric motor on power electronics is proposed, the electrical motor large by measuring with a measuring device and creates a parameter file with motor parameters based on the measured motor sizes or reads the motor parameters from a data memory.
- a control device controls the electric motor with respect to at least the temperature as a motor parameter on the basis of the further motor parameters from the parameter file. It is beneficial that additional engine parameters are recorded and saved in the form of the parameter file. This means that operating points that have already occurred can be optimally regulated and critical areas can be identified at an early stage. This leads to a lifespan extension of components to be commutated by avoiding overload. It is also advantageous that the method runs parallel to the temperature determination.
- the further motor parameters of the electric motor in question are the speed, the motor voltage, the current strength and / or an output of the motor. Since these specific motor parameters have a significant influence on the temperature development during the operation of the electric motor, the monitoring of these parameters optimizes the temperature-dependent control of the electric motor.
- the measuring device and the control device of the electric motor or motors is or are present in the power electronics or are connected between the power electronics and the electric motor. It is advantageous if the optimal circuit can be flexibly selected depending on the application.
- an embodiment is favorable in which the power electronics and the measuring device and the control device are arranged centrally on a common circuit board.
- the advantage of this is that the compo- number of components is significantly reduced, which noticeably reduces assembly and maintenance costs.
- the power electronics and the measuring device as well as the control device are arranged completely or partially integrated in the electric motor unit of the respective electric motor, thus decentrally. This significantly simplifies the control of a number of electric motors operated independently of one another, since the power electronics only have to relate to the parameters of the one electric motor in each case.
- the method according to the invention is designed such that the at least one electric motor is designed as a fan or a compressor. As a result, the method is suitable for several different applications and the possible uses are increased.
- Electric motor are determined and from the respective winding resistance and / or the winding inductance, the electric motor is designed on the basis of stored parameter maps or using a stored computing algorithm. As a result, functional safety is increased.
- the motor parameters determined are also used for stored motor or temperature models that are incorporated into the control of the respective electric motor.
- the method according to the invention preferably enables an error evaluation based on the engine parameters or the parameter file to be carried out in a targeted manner in the event of a malfunction or a damage event, all of the parameters recorded being able to be incorporated directly or indirectly into the evaluation. This has the consequence that the error evaluation is optimized, since in the In the event of damage, the critical engine parameters can be identified precisely.
- a system preferably comprises at least two electric motors for monitoring at least the motor temperature as motor parameters when operating the electric motors, the power electronics with an intermediate circuit and an intermediate circuit voltage provided on an intermediate circuit capacitor for supplying the electric motors.
- Each electric motor has an output stage and an EMC filter, and the power electronics and the measuring device and the control device are arranged centrally on a common printed circuit board.
- the invention provides that the system comprises at least two electric motors for monitoring at least the motor temperature as motor parameters when operating the electric motors, the power electronics with an intermediate circuit and an intermediate circuit voltage provided on an intermediate circuit capacitor for supplying the electric motors.
- Each electric motor has an output stage and an EMC filter, and the power electronics and the measuring device as well as the control device are arranged for each electric motor completely or partially integrated in the respective electric motor unit.
- FIG. 1 shows a system arrangement for the method with three electric motors, each with an integrated power or measuring device
- FIG. 2 shows a system arrangement for the method with three electric motor with a central power or measuring device on a printed circuit board.
- FIG. 1 shows a system arrangement for the method with an electric motor 1, a fan 9 and a compressor 10 with fully or partially integrated power or measuring device 2, 3.
- Each of these electric motors 1, 9, 10 has a separate power electronics 2.
- the power electronics 2 is connected to an intermediate circuit and an intermediate circuit voltage provided on an intermediate circuit capacitor for supplying the electric motors 1.
- Each electric motor 1 has a DC / AC output stage and an EMC filter which, like the measuring device 3 and the control device 4 of the electric motors 1, are arranged in the power electronics 2.
- the power electronics 2 and the measuring device 3 and the Regelungsvorrich device 4 are integrated in the electric motor unit.
- the electrical motor sizes are recorded by measuring with the measuring device 3 and a parameter file 6 with motor parameters 4 is created on the basis of the measured motor sizes or the corresponding motor parameters 4 are read out from the data memory 7.
- control device 5 controls the electric motor 1 with respect to at least the temperature as a motor parameter on the basis of the further motor parameters 4 from the parameter file 6 or the parameter maps 11.
- FIG. 2 shows a system arrangement for using the method according to the invention with an electric motor 1, a fan 9 and a compressor 10 with a central power device 2 or measuring device 3.
- the system structure differs only in that the power electronics 2 differ ,
- the measuring device 3 and the data memory 7 are arranged on a common printed circuit board 8.
- FIG. 1 For the rest, reference is made to FIG. 1 to avoid repetition insofar as the same reference numerals are involved.
- the embodiment of the invention is not limited to the preferred exemplary embodiments specified above. Rather, a number of variants are conceivable which make use of the solution shown, even in the case of fundamentally different types.
