RFID Solution for Data Acquisition in Stator Production

Chinese electric motor manufacturer ensures quality and traceability of stator production by using Turck's RFID system to track the workpiece carriers

A Chinese system integrator automates the quality assurance and traceability of its customer’s motor stator production using RFID technology. The company chose Turck’s BL ident RFID system, which can be seamlessly integrated into the existing systems thanks to multi-protocol Ethernet. The solution enables flexible production on complex mixing lines, provides actual data for production management and allows comprehensive production monitoring. Turck’s robust RFID technology guarantees reliable read processes even under harsh conditions, thus increasing the productivity and efficiency of the production line.

RFID tags store production data and enable unique identification of the material on the carrier plate
Turck’s compact TBEN-S2 RFID interface ensures fast and reliable data transmission
With 10 billion write operations, the TW-R30-K2 also guarantees very good readability in the long term
Turck’s robust Q80 HF read/write head enables reliable RFID detection

With the rapid rise of electric vehicles in recent years, the automotive industry has changed considerably. A key component of these vehicles is the electric motor, consisting of a stator and a rotor. Assembling the stator requires maximum precision, especially with regard to the winding and connection of the cables. The materials and components used must be logged throughout the entire production process and be traceable at all times.

A Chinese automobile manufacturer therefore commissioned its system integrator to implement a solution for recording this data for its motor stator production in order to ensure the quality of the motors already in the production stage and to also be able to document the use of the correct materials over the long term.

Digital workpiece carriers as the ideal solution

Digitized workpiece carriers with embedded RFID tags proved to be the ideal solution. They enable unique identification of the material on the carrier plate, as they can be read and written contactlessly and reliably, even in demanding environments. RFID tags can also store larger amounts of data and are more resistant to soiling than barcodes.

Improved traceability and productivity

At the start of the assembly line, the relevant data is written to the RFID tag on the pallet. As soon as a stator is placed on the pallet, the system writes a range of different information, including the product ID, from the Enterprise Management System (EMS) to the RFID tag.

For efficient and reliable data acquisition, the system integrator opted for a TBEN-S RFID interface, which as a Turck multiprotocol device also supports Profinet and offers a 16 kByte data buffer per channel for fast read processes. The module provides a mode in which it automatically reports data to the controller as soon as a tag is located in the detection range of the read/write head. This automatic data reporting function simplifies the programming of the PLC and reduces the load on the control system and the network in the process.

The Q80 HF read/write head with its extended read distance used in the system guarantees reliable operation of the RFID system, even if a tag is not located in the center of the read range with millimeter precision. For the choice of tag, the system integrator opted for the TW-R30-K2 FRAM chip, which supports up to 10 billion write operations.

By implementing Turck’s RFID system, the system integrator was able to ensure reliable tracking of the materials during stator assembly. Turck’s robust RFID technology in IP67 ensures that the carriers can be reliably read even under harsh environmental conditions, thus increasing the overall productivity of the production line and leading to a significant increase in operational efficiency.

“By using Turck’s RFID products, we have achieved reliable material traceability in the stator assembly process. This not only opens up the data flow in production, but also provides effective data support for production decisions,” the system integrator sums up.
