RFID solution for motor production

Since 2004 VEM, manufacturer of system and engine solutions, has been testing the implementation of RFID tags to collect data right on the motor. In the year 2005 the technology was introduced. The latest transponder generation allows users to read and write detailed product information, proofs of maintenance and custom data during operation without further documents. At the production location in Wernigerode VEM serially equips the newly developed Transnorm motors of the size series 400 with RFID, smaller series can be optionally equipped. „The demand for Memory Motors increases“, reports Sebastian Chyla, graduate engineer, VEM, during the visit of „RFID im Blick“ at the plant in Wernigerode.

Almost every motor is an individual item

With three company locations in Dresden, Wernigerode and Zwickau and an annual production of 59,000 engines, VEM is one of the largest engine manufacturers in Europe. The products range from micromotors to wind turbines and power plant machines. Around 240 motors of different sizes from shaft height 112 to 400 millimeters are produced every day at the VEM plant Wernigerode. Customer wishes have a significant influence on the production: „It is common practice that each of the 240 motors is an individual item“, Chyla reports. „We are more and more turning into an individual producer. Currently 1,4 is the average lot size of the orders.“

RFID as extended digital name plate

An assembly card and a name plate serve to identify the motors during and after the production. Every motor is overcoated at the end of the process. „All barcodes, plates and signs for identification are theoretically unreadable afterwards“, says Chyla. Although RFID was not used for internal purposes, this problem had been the reason to think about using RFID in the first place, he continues. „Basically we digitalized the name plate back then. Now by means of a data variety specifically adapted to the customer's needs, version 2.0 has the advantage that every customer can save their own data on the transponder in addition to technical information.“ If required by the customer, VEM equips the motor with an RFID transponder, size 400 features RFID as a standard.

Product specific manual

RFID technology offers various advantages to the user which range from simple identification to the constant availability of application-specific setting information, as Chyla explains: „Every motor can be identified by the name plate in general, however: according to the field of application it might become unreadable. In cases of delivering larger quantities – we provide among others all AIDA ships with motors – the customer also knows exactly where to place the machine. If for instance the package leaflet gets lost, the according information cannot be found on the name plate but on the RFID chip.“ Even parameters about the specific operation of the motor are available any time with RFID: „When it comes to using converter motos, the converters have to be specifically adjusted. We measure the engines at the production plant and save the measured data on the transponder. Thus it's possible to check exactly at the connected machine, whether the values match the guide values.“

Motor saves his history

The RFID transponder enables the motor to „remember“ his history: Thus every performed service and maintenance can be noted on the transponder. Detailed instructions about maintenance procedures can be recalled by the stored serial number. Motors are also often modified on site by VEM or by intermediaries according to customer wishes. The RFID tag allows to document every machine modification so that all changes remain comprehensible in the future for further users.
