Abstract

The disclosure relates to an assembly composed of two or more electric drives, each of which is provided with a housing that is preferably closed all around; a transceiver or radio transmitter inside the housing of each electric drive is configured for wireless data communication with a master controller; for this purpose, a properly mounted transmission opening is provided in each housing in order for data to be transmitted and received through the transmission opening.

First claim

The invention claimed is:

1. An assembly comprising two or more electric drives, each of which is provided with a housing, wherein a transceiver or radio transmitter is provided inside the housing of each electric drive, wherein the assembly is configured for wireless data communication with a master controller, for which purpose a properly mounted transmission opening is provided in each housing in order for data to be transmitted and received through the transmission opening, wherein the respective transceivers are arranged on a motor circuit board directly behind the respective transmission openings of the slave units such that they are oriented on the circuit board towards the master.

2. The assembly according to claim 1 , wherein two or more transmission openings are provided within each housing of the respective electric drives.

3. The assembly according to claim 1 , wherein the housing of the electric drives is configured as a shielded housing resulting in EMC shielding at the same time.

4. The assembly according to claim 3 , wherein housing of the electric drives is configured as a non-metallic housing.

5. The assembly according to claim 1 , wherein the transmission opening(s) seal(s) housing against the ingress of dust and dirt by means of a non-metallic housing seal, but remain(s) transmissive for data transmission.

6. The assembly according to claim 1 , wherein the respective transceivers or radio transmitters are integrated on the motor circuit board of the electric drive, in particular directly and immediately behind a transmission opening.

7. The assembly according to claim 1 , wherein the transmission openings form a cable bushing within housing at the same time.

8. The assembly according to claim 1 , wherein the transceiver(s) or radio transmitter(s) is/are accommodated in a non-metallic terminal box of the electric drives.

9. The assembly according to claim 1 , wherein the wireless transmission technology is implemented by means of standard transmission methods including at least one of Wi-Fi, Bluetooth, ZigBee, LoRaWan, GSM, UMTS, LTE, and infrared, and the transceivers are configured for such transmission method.

10. A refrigeration or air-conditioning system, comprising an assembly according to claim 1 , configured as a wirelessly communicating master/slave system, wherein the controller is configured as a master and the electric drives are configured as slave units.

11. The refrigeration or air-conditioning system according to claim 10 , wherein the transmission openings of the slave units are oriented towards the master.

12. The refrigeration or air-conditioning system according to claim 10 , wherein, for changing parameters of the electric drives, an access code is assigned per serial number of the respective slave unit, and in that the master has its own access code.

13. The assembly according to claim 1 , wherein housing is closed all around.
