    Tips: Stainless steel servo motors for food packing machine

    Stainless steel is the optimal material for corrosion resistance chemical substance and high pressure water flow, which makes it become an important part of food packing machines.
    Stainless steel servo motor can reduce extra hardware and improve cleanliness, reliability and performance of machines at the same time. The motors adopt smooth and round design which is easy for cleaning, since meat and fluid will not easily gather in surface. The motor is made of grade-300 stainless steel and it will have special treatment after finishing components to remove impurities and further improve corrosive protection performance. In addition, cable outlets of motors are sealed when they leave factory, which can improve product reliability to the utmost extent.

    Good 6hp servo motor
    The 6hp servo motor was received, and the noise was very small and running. The store’s pre-sales and after-sales services are in place, thank you.
