Definitions
- the present invention relates to a circuit and a method for determining the rotor position at low speed or at rotor standstill.
- the speed or position of the motor rotor can be determined indirectly by measuring only electrical quantities (e.g., phase voltage and / or phase current).
- electrical quantities e.g., phase voltage and / or phase current.
- the position of the rotor can be determined by electromotive force (EMF) or by position-dependent inductance (also referred to as anisotropy or magnetic flexibility).
- EMF electromotive force
- position-dependent inductance also referred to as anisotropy or magnetic flexibility
- the rotor is referred to as a rotor, regardless of whether a rotational or translational movement is performed.
- a rotational or translational movement In a translation
- the determined position angles are converted into correspondingly traveled distances.
- WO2004019269A2 a rotor position detection is described, which is operated with pulse width modulation.
- a pulse pause a high-frequency (HF) signal is fed into the electric motor. From the received return signal, the rotor position is estimated.
- the disadvantage here is that the RF response signal is modulated onto the normal pulses. This requires a corresponding filtering of the pulses, which results in an inaccuracy.
- US696746B1 a method has been described that represents an improved method for RF signal injection.
- Object of the present invention is to eliminate the disadvantages of the prior art by means of an arrangement and a method for evaluating the signals obtained.
- the filter consists of at least one capacitor. In a combination of this capacitor and a coil, the filter comprises an LC element. In a combination of the aforementioned capacitor and a resistor, the filter comprises an RC element. The filter is switched to high pass.
- the Clarke transformation is used to determine the rotor position.
- the voltages to the stator coils are transformed into two non-zero components (w "and wp) and a zero component (u 0 ): where u v , u v and u w denote the voltages of the stator coils U, V and
- a high frequency (RF) voltage signal is impressed into the zero component.
- the filter at the star point causes the passage of the RF signal and blocks the other frequency components of the zero component.
- the RF signal There are several ways to impress the RF signal.
- the first possibility is via a signal generator which is connected directly or via a transformer to the filter at the neutral point.
- the frequency range is from 1 to 100 kHz.
- the second option is to use pulse width modulation (PWM) for motors with inverters (inverters).
- the filter at the neutral point is connected to the inverter.
- the PWM-controlled inverter generates a zero component with a frequency equal to the switching frequency of the inverter. It is also possible to use harmonics of the switching frequency or a low-frequency HF signal fed into the PWM.
- Magnetic features are present in most engines, albeit to a lesser extent. Due to the magnetic properties, the HF voltage signal, a current component in the non-zero component (i a and i ß ) impressed, from which the rotor position can be determined.
- ⁇ ⁇ , i v and i w are the currents of the stator coils U, V and W.
- the measured current must first be filtered in order to eliminate other frequency components which do not correspond to the frequency of the RF signal.
- k c is a constant that depends on the motor, and ⁇ is the rotor position.
- the constant k c is up to four times higher than in conventional methods where the RF voltage signal is impressed into the non-zero component.
- the filtered current signals i a and i ⁇ are demodulated.
- the demodulation is carried out by multiplying the current signals by the signal sin (cö c and is filtered by means of the following low-pass filter.)
- the rotor position is determined as the rotor angle by calculating arctan2 of the two demodulated signals and then dividing by 2:
- the rotor position can be determined from the two demodulated signals via a phase locked loop (PLL).
- PLL phase locked loop
- the current is sampled synchronously with the pulse width modulation.
- the times at which the current is sampled are 90 degrees offset from the zero crossing of the zero component. So that the position can be determined according to the invention, the current values should be sampled immediately before the zero crossing of the zero component. This is possible by shifting the sampling time or by modifying the space vector pulse width modulation.
- i dif k la k ⁇ la (fc-1)
- i ' ⁇ dif k Z ' ⁇ fc - Z ' ⁇ (fc-1) where ke is the sample number.
- the demodulated signals / t and k are then filtered with a low-pass filter, in which, for example, the instantaneous value and the value of the previous sampling period are averaged:
- i ' av k ⁇ 2 (quarrel k + £ adem (fc-1))
- Z ' ßav fc ⁇ (i ' ßdem / fc + Zßdem (fc-1))
- T s is the sampling period
- the rotor position is called rotor angle by the calculation of arctan2 of the signals iaav k and , and subsequent division by 2.
- the rotor position can be determined from the two signals via a phase-locked loop (PLL).
- PLL phase-locked loop
- the RF signal is fed continuously or the PWM outputs a signal to generate or initiate the RF signal. Accordingly, the sampling of the current values, in which a signal is output by the PWM, detects the current component or the current component is constantly detected.
- Another alternative is to generate the RF signal by the PWM by sending the PWM pulse for zero crossing as an RF signal with a frequency in the range of 1 kHz to 100 kHz, preferably 75 kHz.
- the current component is determined. This makes it possible to send an RF signal at each zero crossing of a phase and to determine the current share after the filter.
- the determination of the current component comprises the determination of a signal which is proportional to the current component.
- the evaluation is carried out by determining the derivative of the signal.
- Another alternative is to send at least parts of the PWM pulse outside the zero crossing as an RF signal. This means that no waiting is necessary until the next or the next zero crossing of a phase. This makes it possible in a time-shifted sequence each to send an RF signal and to determine the current share after the filter.
- the RF signal is fed in addition to the PWM pulse, e.g. at the zero crossing or in the pauses between two PWM pulses.
- the rotor position is calculated by means of trigonometric functions from the determined current component or current component signal.
- the rotor position can be determined by current signal evaluation by means of phase-locked loop (PLL).
- PLL phase-locked loop
- a filter is connected to the neutral point of the stator coils.
- the filter comprises a capacitor, LC element or RC element.
- the filter is connected to a voltage source.
- the voltage source comprises a signal generator, an inverter, an inverter or the PWM signal generation.
- At least two stator coils are each equipped with a current connected measuring device.
- the current measuring device comprises a transformer, one or more coils with or without ferrite core, individual wire windings with or without ferrite core, conductor tracks with ferrite core on a double-sided or single-sided circuit board.
- the dimensions of the rotor are not limited. Preference is given to using rotors with a diameter of 3 mm to 5 m, particularly preferably 1 cm to 30 cm.
- the number of poles is also not limited. Preference is given to using motors having a number of poles of 3 to 100, more preferably 7 to 50.
- the RF signal is fed in addition to the PWM pulse. In this case, an RF voltage signal is fed into the neutral point of the stator windings during a PWM pulse. The RF signal passes through the stator coils.
- the RF signal that has passed through the stator coils causes a non-zero component in the three-phase system (alpha-beta or d-q component). From this non-zero component, a current share signal is generated.
- the current share signal comprises the current component, a different proportion of the current component or the derivative of the current component.
