Definitions
- Circuit arrangement for the selective operation of at least two electrical machines
- the invention relates to a circuit arrangement for operating at least two electrical machines with different inductance requirements on a converter power unit.
- Machine driven used.
- the replacement of the spindles is usually done by a tool robot.
- the two driven by synchronous motors spindles are to be operated inexpensively on a power unit.
- the electrical machines are often designed as synchronous motors. Due to the necessity of operating the electric machines with a specific power in the field weakening range, a choke inductance as a ballast inductance (ballast inductance) is required, which must be adapted to the inductance of the respective electrical machine. Therefore, a cost-effective interconnection of reactor inductances and electrical machines is sought for the two operating cases.
- a circuit arrangement for the selective operation of at least two electrical machines, which are respectively supplied via a plurality of phase lines comprising:
- a voltage protection module for limiting a DC link voltage
- a switch arrangement for selecting one of the electric machines by switching the phase lines; - First inductor inductances in each of the plurality of phase lines between the switch assembly and the voltage protection module, wherein in parallel to one or more of the first inductor inductance in each case a second inductance inductance can be switched depending on the selected electric machine.
- the circuit arrangement advantageously allows the number of components required for operation of two electrical machines are needed on a power unit to reduce.
- the voltage protection module can be designed to short-circuit the phase lines as a function of a DC link voltage.
- the second inductor inductance can be switched by a contactor depending on a switching signal, wherein the switching signal is provided for driving the switch arrangement.
- a drive system with the above switching arrangement and with a plurality of electrical machines is provided.
- the first inductor inductances can be designed such that a first of the electrical machines is operable in field weakening operation
- the second inductance inductors can be designed such that a second of the electrical machines with in at least one of the phase lines connected in parallel first and second reactor inductance in Field weakening operation is operable, wherein upon selection of the first electric machine, the second throttle inductances are not switched on and wherein at
- a method for the selective operation of at least two electrical machines, which are respectively supplied via a plurality of phase lines, and wherein a voltage protection module is provided for limiting an intermediate circuit voltage, wherein one of the electrical machines is selected by switching the phase lines, being parallel to one or more first
- Inductance inductors which are arranged in each of the plurality of phase lines between the switch arrangement and the voltage protection module, in each case a second inductor. depending on the selected electric machine is switched on.
- 1 shows a schematic representation of a drive system with two selectable motors
- 2 shows a schematic representation of a drive system with two selectable motors according to an embodiment of the invention.
- FIG. 1 schematically shows a basic circuit 100 for operating two motors 1, 2 on a power section 3.
- One of the motors 1, 2 is selected by a selection switch 4.
- the power unit 3 is connected to the motors 1, 2 via a voltage protection module (VPM, Voice Protection Module) 5 with a first changeover switch 6 and a second changeover switch 7.
- the switches are designed as contactors.
- the voltage protection module 5 is a safety module and ensures that no higher voltages than 830V can occur in the converter DC link, thus the voltage protection module VPM primarily contributes to the inverter protection, and it ensures that the spindle is braked in a defined time. This is achieved by shorting the three phase lines.
- the circuit shown in FIG. 1 furthermore has the following features:
- the motors for example, correspond to spindle motors and are designed in synchronous technology, ie, that there are permanent magnets in the rotor, which generate the excitation of the motor.
- the upstream inductor inductances are required, which must be adapted to the inductance of the respective motor 1, 2 respectively.
- the motor acts like a generator.
- an EMF can arise up to 2kV.
- the voltage protection module 5 limits this voltage to a maximum of 830 V in that the three phase lines (power lines) are short-circuited.
- the circuit / arrangement of the components must be selected such that a secure limitation of the EMF on the phase lines is ensured even in the event of power failure.
- the voltage protection module 5 remains connected to the motor (spindle) 1, 2, to ensure the limitation of the EMF to 830V. This is not fulfilled in the above proposal of FIG. 1, since the change-over switches 6, 7 designed as contactors in FIG.
- the circuit arrangement 101 of the components to be interconnected has been selected such that the worst-case case of a failure of the power section 3 is reliably controlled both during operation of the motor 1 and the motor 2 and thus no unsafe states can occur.
- the voltage protection module 5 is connected to the power part 3 via three phase lines.
- the voltage protection module 5 is connected to one of a motor arrangement with a plurality of motors 1, 2 via three phase lines.
- the motor arrangement comprises the motors 1, 2 to be controlled via the common power unit 3, wherein the motors can only be operated individually on the power unit 3.
- the motor arrangement has a changeover switch 4, which selects the respective motor 1, 2 according to a specification and connects it to the phase lines of the voltage protection module 5.
- In the phase lines between the voltage protection module 5 and the switch 4 are each a first inductance inductance. 8
- second inductor inductances 9 ⁇ can be connected via a respective switch 10.
- the switch 10 is switched depending on the switching of the switch 4 and preferably driven with the same signal.
- the worst-case case can be e.g. come about when one of the motors 1, 2 runs at maximum speed and exactly at this time the inverter located in the power section 3 fails due to a mains voltage failure or other error due to pulse cancellation.
- Inductor inductances 8, 9 ' are required to operate the motor at a certain power in the field weakening range.
- the inductance of the corresponding throttle inductances 8, 9 ' is dependent on the power of the motor 1, 2 to be operated therewith, the field weakening operation that has been run and the achievable maximum speed of the motor.
- An advantage of the circuit arrangement of FIG 2 is that the interconnection of the components has been chosen so that the requirements (limitation of the EMF in the worst-case case) can be reliably ensured. This is achieved by the always continuous and non-disconnected connection between the voltage protection module 5, the first inductor inductance 8 and the currently selected motor 1, 2. This is especially ensured even if e.g. due to power failure of e.g. trained as a contactor switch 10 changes its switching position.
- the circuit also has the advantage that an additional contactor between the voltage protection module 5 and the throttle inductances 8, 9 'is not required, whereby the total number of components can be reduced.
- the switch 10 is turned on only when using the motor 2.
- the required total inductance for motor 2 is produced via the switched-in inductor 9 ', the inductance of the parallel connection of the inductance 8 and the inductance 9' being the total inductance in each phase line.
- the motor current can always flow through the inductance inductance 8 via the voltage protection module 5 and thus the EMF of the motor 2 is safely limited.
- phase lines three are assumed in the above-described embodiments, and the number of phase lines may be larger or smaller. Furthermore, instead of only two motors, an arbitrary number of motors can be provided, which are individually selectable. Depending on the selected engine, either no second throttle inductances or the second throttle inductances 9 ⁇ assigned to the respective motor are connected in parallel with the first throttle inductances 8.
