While servo motors and drives are prevalent in a wide variety of industrial applications, what should be considered when they operate in extreme or hazardous environments? In many cases, the motor itself operates in the extreme environment, while the drive electronics are protected from hazards. This blog addresses the servo motor performance challenges and the design considerations needed when a motor operates in extreme environments.

Every machine builder knows that they have to meet stringent safety requirements to protect workers from the risk of injury. If they build machines for the EU market, they should know that the European regulatory landscape is more advanced than in most other regions, with newer and more rigorous requirements for safety design and testing.

How do I calculate a motor’s continuous torque when it is operating in an environment above its rated temperature? Since the motor’s continuous torque (Tc) is rated in a 40°C ambient, how can I estimate the motor’s continuous torque during my worst-case ambient temperature of 55°C?  

In the automation world there can be a fine line between what is considered a motion controller and what represents a basic servo drive.  It is critical to understand the functionality and intelligence of each device since, in many applications, both a motion controller and a servo drive are required to complete the system.

A motion controller is a programmable device that manages connected electronic drives and motors to perform specific functions for automating and controlling machinery.  Motion controllers can range from very simple microprocessor chips embedded into the electronics of 3D printers to sophisticated multi-axis CNC systems operating precision machining centers. 
Using a conventional single motor and gearbox style setup on your horizontal flow pack machine could be the reason you’re not realizing the flexibility and performance you need to keep up with demand.

For manufacturers looking to offer personalization capabilities, true mass customization to batch size of one will require more than purchasing the latest 3D printer or equipment. It’s important to understand the entire supply chain involved, from product ideation and design to manufacturing and logistics.

Working with motion control experts like Kollmorgen makes selecting a servo system easier and faster, resulting in an optimal system for the application.

There are lots of reasons to choose a frameless motor. They’re extremely compact, simple, efficient and precise. Is that what your application requires?

An explosion proof motor is clearly marked with a nameplate that identifies its suitability for a given hazardous environment.  The nameplate will indicate the hazardous Class, Division, and Group for which the motor is suited.
