تجهیزات زیادی نقش محافظتی موتور را عهده دار هستند، یکی از این تجهیزات بیمتال زیمنس می باشد. بیمتال ها موتور را در مقابل جریان های اضافی که سبب آسیب رسیدن موتور می شود را حفظ می کنند. از دو نیمه هادی با ضرایب انبساطی متفاوت ساخته می شوند. این فلز ها با زیاد شدن تغییر طول می دهند و قطعه هادی بیمتال به سمت فلز با ضریب انبساطی کمتر خم می شود. اگر بخواهیم دقیق تر بگوییم در ساختمان داخلی بیمتال ها از دو نوع فلز آهن و برنج که بر روی هم پرس شده اند استفاده می گردد.
