The increasing trend towards miniature multi functional devices brings with it the problem of electromagnetic interference (EMI).

There are many ways in which we can help you achieve electromagnetic compatibility (EMC).

Varistors
To reduce the effects of radiated noise we can offer dc motors with an internal varistor ring. This device is fitted across the motor coils and offers low cost suppression.

 

Filters
The effects of electromagnetic noise can be reduced by fitting capacitors and chokes close to the dc motor. We offer a range of populated pcb’s that can be fitted directly across the motor terminals.

Wiring looms
We can design and manufacture wiring looms which incorporate twisted power leads, electromagnetic shielding and ferrite beads, all of which offer significant reductions in EMI.
