Definitions

  • the invention relates to an electrical drive arrangement with a direct current motor, in particular with a permanent magnet excited air coil motor, with a control circuit with an electronic commutator.
  • Phase current shaping is a new development in the field of electronic commutation of motors for hard disk drives.
  • the phase current is modulated in the three individual phases with the purpose of achieving a certain - for example approximately sinusoidal - course of the phase currents.
  • the motor voltage is pulse-width modulated (PWM), otherwise the switching losses would be very high.
  • PWM duty cycle serves as a manipulated variable. Because of the difficult zero crossing detection of the induced voltage, this method generally requires a PLL-supported commutation control.
  • phase current shaping is not readily transferable to air coil motors (for example with a foil winding). Compared to the iron anchor types, these have considerably smaller electrical time constants (about a tenth) and require a correspondingly higher clock frequency of the PWM, which in turn can only be achieved with increased effort.
  • Another method for reducing the torque ripple solely by modifying the current in the intermediate circuit and while maintaining the conventional I20 ° block commutation, preferably by sensorless commutation (EMF commutation), is specified in EP 0773624.
  • EMF commutation sensorless commutation
  • the signal for this is obtained from the discharge process of an RC element.
  • the torque ripple can only be reduced to a certain extent in this way, since it is important to keep the product of current and flow chain change constant at all times. This requires constant adjustment of the current.
  • This method is not very suitable for motors with a very small electrical time constant.
  • a control signal is derived from an induced motor voltage detected by means of a measuring device and from a reference value which is used to regulate the speed of the DC motor, and in that the derived control signal is used by adjusting the motor currents (ia, ib , ic) to cause a substantially constant torque of the DC motor.
  • This motor control reduces the commutation-related torque ripple of low-inductivity DC small motors.
  • the 120 ° block commutation with zero crossing detection is maintained and only the intermediate circuit current is modulated, which means that the individual phase currents are not modulated and a conventional commutation method such as sensorless commutation (EMF commutation) can be used.
  • EMF commutation sensorless commutation
  • the embodiment according to claim 2 enables a simple determination of the reference value for the motor current at which the motor torque is constant.
  • the embodiment according to claim 3 enables a determination of the reference value for the motor current at which the motor torque is constant, even if the motor speed is not constant.
  • the embodiment according to claim 4 allows a simple setting of the intermediate circuit current by means of a series regulator and an actuator by the control signal.
  • the actuator can be dispensed with by directly controlling an inverter belonging to the commutator by the controller.
  • FIG. 1 shows a block diagram of an electric drive arrangement according to the invention
  • FIG. 2 shows the more precise structure of the reference value determination of the motor current in block 4,
  • FIG. 3a shows a basic circuit diagram and FIG. 3b shows a practical approximation of the signal processing which takes place in block 6 and FIGS. 4a to 4h the course of some signals in the engine control.
  • the entire drive consists of an inverter 1, a direct current motor 2, an EMF commutator 3 as well as a block 4 for obtaining the reference signal and a block 5 which converts this reference value for the intermediate circuit current with the aid of an actuating intervention to see.
  • the EMF commutator 3 works with 120 ° phase shift in block mode and with zero crossing detection, the abbreviation EMF (electro-motive force) stands for sensorless commutation, which measures the induced motor voltage in the currentless of the three phases Ea, Eb, Ec ,
  • EMF electro-motive force
  • Torque ripple which is why a block 4 is added with a new circuit.
  • FIG. 2 shows the structure of block 4 for reference value formation in detail. Its input variables are on the one hand the commutation signal V_FG, shown in FIG. 4b, the measured induced voltage E_sample, shown in FIG. 4a, where ⁇ denotes the electrical angle of rotation of the motor 2.
  • the EMF commutator provides these two sizes.
  • V_i_av which outputs a control circuit (not shown here) with which the speed of the motor 2 can be set.
  • the signal V_i_av is the reference value generated in a superordinate speed control for the time average of the motor current. Since the two signals V_FG and E sample are already available in the EMF commutator 3, only an additional new block 4 is required in order to minimize the torque ripple of the motor 2.
  • the reference value for the current motor current is now obtained in block 4, as shown in FIG. 2, by first doing E_sample in every second commutation period is inverted and the signal E_sample2 generated in this way is integrated, which results in the signal dFlux.
  • a filter can also be connected between inversion and integration in order to filter any DC component that may be present from the signal E_sample2.
  • the course of dFlux can be seen in Fig.4d.
  • the signal dFlux is then forwarded to block 6, the functioning of which is explained below.
  • the reference value V_i_ref for the instantaneous value of the motor current, which causes a constant motor torque, can be obtained from the signal dFlux by the relationship given in FIG. 3a.
  • the signal flux from FIG. 4e is obtained using the relationship 1 + cl * dFlux.
  • a normalization factor cl is set so that there is a ratio of the maximum value to the minimum value of the signal Flux, which corresponds to the ratio of the maximum value to the minimum value of the rectified induced voltage. For an ideal three-phase motor, this ratio is a factor of 2I-J3.
  • the factor cl must be adapted to the current speed, but this is possible via an arithmetic logic unit using the speed-dependent signal V_FG.
  • the algorithm described in FIGS. 2 and 3 can be implemented using either analog or digital signal processing.
  • the signal V_i_ref is the reference variable for the current i_dc of an intermediate circuit controller 8, which can be set with the aid of a target / actual value comparison with subsequent control intervention via an actuator 5. This can be done, for example, by a series regulator 8.
  • the intermediate circuit current i_dc is then commutated by the inverter 1 into the three phases.
  • the output of the controller 8 can also be used as a reference variable for a common actuation intervention on the inverter transistor 1, which is shown in broken lines in FIG. 1.
  • the supply voltage is v_bat and DC link voltage v_dc identical, since the actuator 5 is omitted in this embodiment.
  • the control of the inverter 1 turns out to be more complicated, since it no longer only takes over the commutation, but also has to regulate the torque ripple, which requires coordination of the two processes in an electronic circuit 7.
  • 4h shows the motor current ia of a phase Ea with minimal torque ripple, the other motor currents are then respectively out of phase by 120 °.
