ZE-Motor® (Zero Emission Motor)

Elektro-ceramic devices from ST

have been being used

by the global leaders in drive technology

and are instrumental in prolonging service life

as well as substantially reducing electromagnetic noise

Since the mid-1960s, Sintertechnik (ST) has been developing and manufacturing customised solutions for the reduction of electromagnetic noise and service life prolongations of small motors. For 30 years now, the two worldwide market leaders in drive technology have been using ST products in series, and these components have proven to be suitable for even the most unusual of conditions (e.g. on planet Mars!), as well as for vehicle or aircraft applications or in medical technology. Besides clearly reducing electromagnetic noise, the use of ST products can also extend the service life of certain motors significantly.

Devices for EMR reduction and prolonged service life in electric motors

The ever increasing use of small motors in every facet of our daily lives (e.g. electric windows or sunroof in cars, hairdryer, printer, DVD-player, PC, etc.), results in increasing interference between the devices, triggered by electromagnetic emissions fo the motors itself (“electromagnetic smog”). This problem will worsen in the future as conductor track density in microprocessors continues to increase, so they will become all the more sensitive to electromagnetic interference. Therefore, as early as 1996, the EMC Act (Act on Electromagnetic Compatibility) was passed, stipulating that the function of any and all electronic devices (including electric motors) must not be impaired. This development is documented, amongst other things, in the CISPR25 automotive standard, version CISPR25:2002 of which was applicable to the frequency range of 150 kHz to 108MHz, while the latest version CISPR25:2008 applies to a range of 150 kHz – 2.500MHz.

Since the mid-1960s, Sintertechnik (ST) has been developing and manufacturing customised solutions for the reduction of electromagnetic noise and service life prolongations of small motors. For 30 years now, the two worldwide market leaders in drive technology have been using ST products in series, and these components have proven to be suitable for even the most unusual of conditions (e.g. on planet Mars!), as well as for vehicle or aircraft applications or in medical technology. Besides clearly reducing electromagnetic noise, the use of ST products can also extend the service life of certain motors significantly (see below).

The suppression of the electromagnetic noise of a motor is always a very individual development task. The downloads contain a selection of motors in various power classes where, in some cases, the EMR was reduced substantially. We at ST are happy to develop and manufacture a suitable solution for EMR reduction in your motor!
