This article explores additional servo motor sizing considerations and the often-resulting communication issues that may arise for an application requiring a dominantly maintained load with little movement through an in-depth explanation of the term: Stall, as typically utilized in the servo motor industry. This information is then utilized relative to the axis’ effective RMS force/torque calculation for proper motor sizing.

Producing wholesome quality food is challenging work. In addition to designing and manufacturing creative and tasty products, a laser focus on food safety is necessary for food processing companies to survive and thrive. Effective sanitation of machinery and facilities is critical in the production of safe food products.

When intermittent power density is of a required high value, you may not want to use classic RMS calculations and speed-torque performance curves as your only method to select a servo motor and drive. Doing so might cause an under-sizing of the motor or drive.

Direct Drive servo motor and drive technology not only reduces an axis’ parts count, mechanical losses and often its objectionable noise; Direct drive technology also increases a machine’s efficiency, lowering operation cost for the user due to its inertia ratio, as compared to the more common mechanically advantaged multi-body axis designs. Reducing the mechanical transmission components such as gearboxes, timing belts, pulleys, cams, lead screws and so on, between the motor and its load is only part of the savings!
