Technical Field

The invention relates to a control drive comprising a drive motor, a control unit and a primary energy supply.

Background

In such control drives, it is customary for the primary energy supply to be carried out via a three-phase current connection which provides sufficient power for energizing the drive motor. The energy supply to the control unit with a dc voltage is then effected, for example, by a power supply unit formed by the primary energy supply device. Alternatively, it is also known to supply the primary energy with a dc voltage of 24V, with which the drive is operated in this case.

Disclosure of Invention

The aim of the invention is to reduce the energy consumption for adjusting the drive.

This object is achieved according to the invention by an actuating drive having the features of claim 1.

The actuating drive according to the invention is therefore characterized in that the primary energy supply is used to power the control unit, wherein the primary energy supply has a power which is lower than the rated power of the drive motor, and the actuating drive has a secondary energy supply for powering the drive motor.

In this way, a power supply for supplying the operating voltage to the control unit can be dispensed with, so that the actuating drive is of simpler design.

In one embodiment, the control drive has a connection for a control line, a field bus and/or a photovoltaic system as a primary energy supply. In this way, in particular the control unit can be supplied with energy from a control conductor or energy source having only a low power.

In one embodiment, the control drive has at least one energy store, which can be charged by the primary energy supply.

The energy store can be used to assist the primary energy supply, in particular when the primary energy supply takes place via an energy source with fluctuating power, for example a solar cell. The energy store can compensate for times with little or no insolation.

In one embodiment, the energy accumulator serves as a secondary energy supply for the drive motor. Since the drive motor of the actuating drive is usually moved only very little, the energy accumulator is provided with sufficient time to be charged by the low-power primary energy supply. The energy accumulator can have a sufficient capacity in order to provide a very high energy for driving the motor, also at least for a short time. In this way, the actuator can be operated completely by means of the primary energy supply, the continuous and maximum power of which is less than the rated power of the drive motor.

In this way, the motor can be supplied, for example, by data bus lines or by lines, for example, by photovoltaic connections, in which case the rated power which would otherwise be required is not available.

This can be particularly advantageous if the actuating drive is to be operated at a remote or remote location without the power grid.

In one embodiment, the actuating drive has a power supply connection, in particular a high-current connection or a three-phase current connection, as a secondary energy supply. In this way, the power supply of the control unit can be carried out, for example, by a data bus, so that a power supply for the control unit can be dispensed with. At the same time, the drive motor is supplied independently of this on a line which permanently supplies the required nominal power. This can be particularly advantageous when the adjustment drive must be moved frequently.

In one embodiment, the actuating drive is formed in two parts. In this case, at least the control unit and the primary energy supply are provided in the first part and the drive motor is provided in the second part. In this way, for example, a more flexible construction can be achieved.

In one embodiment, a secondary energy supply is provided in the second part. The secondary energy supply device can be either a power supply connection or an energy store. The first and second parts are in this embodiment connected to each other by a control wire. When the secondary energy supply device is an energy store, the energy store can be chargeable by the control line, i.e. the primary energy supply device of the first part.

In an alternative embodiment, the secondary energy supply is arranged in the first part and the second part are connected to each other by a motor connecting line. In this embodiment, too, the secondary energy supply can be a power supply connection or an energy store.

The energy store can be, for example, any accumulator, such as a lead accumulator, a capacitor, such as a supercapacitor, or another energy store.

In one advantageous embodiment, the energy store is formed as a nickel metal hydride (NiMH) battery. In this way no special authentication is required.

Drawings

The invention is explained further below with the aid of embodiments with reference to the drawings.

Showing:

fig. 1 shows a one-piece actuating drive comprising an energy accumulator as a secondary energy supply and

fig. 2 shows a two-part actuating drive of the power supply connection in the second part as a secondary energy supply.

Detailed Description

Fig. 1 shows a one-piece actuating drive 1, which comprises a control unit 2, a drive motor 3, an energy store 4 and a primary energy supply 5.

The primary energy supply 5 is, for example, a field bus 6. However, the primary energy supply can also be another control line, a data bus or a photovoltaic system.

The primary energy supply 5 is sufficient here to supply the control unit 2, but has a power which is lower than the rated power of the drive motor 3. The energy accumulator 4 serves in this embodiment as a secondary energy supply 7 for driving the motor 3.

The accumulator 4 is preferably a nickel metal hydride battery. However, it can also be any other energy storage device 4, such as a lead accumulator or a capacitor, such as a supercapacitor or a supercapacitor.

The energy store 4 is charged via a primary energy supply 5. The energy accumulator 4 is preferably dimensioned such that the actuating drive 1 can be displaced by at least one, preferably two, complete actuating strokes. This ensures that the actuating drive 1 can be opened and closed again at least once. Furthermore, a significantly higher power can be supplied to the drive motor 3 by the energy store 4 than by the primary energy supply 5.

Fig. 2 shows a two-part actuating drive 1. In the first part 8, a control unit 2 and an optional accumulator 4 are provided. The primary energy supply 5 is realized here by a photovoltaic system 9. However, the primary energy supply can also be realized via a data line or a control bus.

The energy store 4 serves here only to assist the primary energy supply 5, in particular to buffer voltage peaks and to compensate for voltage fluctuations, which can be produced, for example, by shading the photovoltaic system 9.

In the second part 10 a drive motor 3 is arranged. The first portion 8 and the second portion 10 are connected to each other by a control wire 11.

The second part 10 has a secondary energy supply 7, which is formed in the example by a three-phase current connection 12. The three-phase circuit current connection provides sufficient power to operate the drive motor 3. Each of the two components may be provided, for example, in a separate housing.

Other arrangements than the two illustrated embodiments are envisaged. For example, the embodiment of fig. 2 can also be formed in one piece. The embodiment of fig. 1 can also be designed in two parts, wherein the energy store 4 is arranged in the first part 8 or in the second part 10. The actuating drive 1 may also have a plurality of parts. In particular, the energy store 4 can be designed as a separate part, which can be easily replaced.

The application is thus not limited to the embodiments shown.
