    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.

    Existing reviews of 6 hp (4.5 kW) AC Servo Motor, 21Nm, 2000rpm
    A question for your 4.5kW servo motor/controller
    For your 4.5kW servo motor/controller, our performance requirements of the Idle Speed Test require very fast input changes and, likewise, very fast output speed changes. The rotational inertia and the available torque of the motor indicate that these speed changes are within the capabilities of the motor. However, I need to make sure that the motor controller is capable of responding to these fast input changes and also capable of controlling the motor to achieve these commanded output speed changes. What is the response time of the motor controller?

    ATO Responded
    The response time of the motor controller is 500Hz, and it is able to meet the performance requirements of idle Speed Test you inquire about.
