There are many challenges when designing a motion control system. One challenge that can overwhelm many engineers is nonlinear mechanics. These mechanics can make tuning a motion control system difficult. At Galil, we pride ourselves in being able to provide intuitive solutions for these nonlinear or unorthodox mechanics. This webinar will discuss six examples of applications with nonlinear mechanics, their inherent challenges, and the tools/solutions to address these challenges.
Below are the six examples of applications with nonlinear mechanics:

1. High-friction axis
2. Mechanics with backlash
3. Servo axis involving a spring
4. Axis exposed to large and unpredictable outside forces
5. Mechanics where inertia varies with position
6. Hydraulic axis

A clutch is a mechanical device that engages and disengages a power transmission, especially from a driving shaft to a driven shaft.  Clutches are used whenever the transmission of power or motion must be controlled over a time element (ie. electric screwdrivers limit how much torque is transmitted through use of a clutch).

A common way to generate precise linear motion is to use an electric motor (rotary motion) and pair it with a lead screw to generate a linear actuation system.  Depending upon what this linear actuator interfaces with it can be constructed in a number of different ways.  Here we will discuss several different ways to combine a lead screw and nut with a stepper motor to create a linear actuator system…

LEAD SCREW LINEAR ACTUATORS: When to Apply External, Non-Captive and Captive Step Motor Actuators

Servo motors are generally used as a high performance alternative to the stepper motor. Stepper motors have some inherent ability to control position, as they have built-in output steps.

This often allows them to be used as an open-loop position control, without any feedback encoder, as their drive signal specifies the number of steps of movement to rotate. This lack of feedback though limits their performance, as the stepper motor can only drive a load that is well within its capacity, otherwise missed steps under load may lead to positioning errors.

The encoder and controller of a servomotor are an additional cost, but they optimize the performance of the overall system (for all of speed, power and accuracy) relative to the capacity of the basic motor. With larger systems, where a powerful motor represents an increasing proportion of the system cost, servomotors have the advantage….

Power Off Brakes, sometimes referred to as Safety Brakes, Spring Set Brakes or Fail Safe Brakes, are widely used in the industry, usually on the back of motors, to hold a machine, pulley, Z axis, or robotic arm in position in case of a power failure.

A “voice coil” is a generalized term that refers to any galvanometer-like mechanism that uses a solenoid to move an object back-and-forth within a magnetic field. In particular, it is commonly used to refer to the coil of wire that moves the read–write heads in a moving-head disk drive. In this application, a very lightweight coil of wires is mounted within a strong magnetic field produced by permanent rare-earth magnets.

As an integral part of industrial machines and processes, ball screw assemblies often operate in environments with elevated temperatures. Heat can be generated by other mechanical and electrical components in the machine, and in some cases, is a byproduct of the process itself. And, like other motion products with sliding or rolling friction, ball screws generate heat of their own as they run. This heat, and especially the change in temperature that occurs over time, can have a detrimental influence on the screw’s function. But there are ways to mitigate heat and reduce its effect on life and accuracy.

Operating temperature recommendations for ball screw assemblies vary among manufacturers, but the typical upper limit for the most common ball screws is 80° C for short, instantaneous exposure, and 50° C for continuous duty. For standard annealed screws, a temperature over 100° C can cause a decrease in tensile...

Servo motor sizing is often done with the help of a manufacturer’s sizing program, but it’s important to understand the three most critical factors—speed, torque, and inertia—to ensure you select the best-fit motor for the application.

Selecting the right servo motor for a linear motion system is a complex task, beginning with initial assumptions and component selections, which must be checked through a series of calculations and, in most cases, repeated over several iterations until a suitable combination of motor and mechanics is found.

Most motor manufacturers offer online sizing tools that make the process easier, ensure that the best components are selected, and help preserve the design engineer’s sanity. But as a designer, or even an end user, it’s important to have an understanding of the three critical parameters of servo motor sizing: inertia, speed, and torque.

Can my step motor get hot enough to cook an egg?  In this segment of The Why? Series, Bob White, Manager, Training and Digital Marketing at Kollmorgen, explains why a typical step motor may get hot.  Learn why a step motor will heat up, and what can be done to reduce this heating…unless of course, you are looking to cook an egg!
