Let's face it. Motion control projects are fun. Sure, we may be a little biased, but if you're reading this we bet that you agree. We also bet that like us, you're always looking for a good deal. Well, let the worlds of motion control and good deals come together again... Applied Motion presents Closeout Sales on step motors and servo motors.

If you read our article Why Do Step Motors Get Hot? you may have wondered "What does this mean to me?” Step motor losses are important because the energy lost in the motor results in heat. Any motor has a thermal constant that can be used to compute how hot the motor will get for a given level of energy dissipation. Once the windings exceed 130°C, the insulation on the motor windings will melt and it’s game over.

Step motor motion is conceptually simple: Just rotate the stator field and the rotor will follow, so long as you don’t expect it to violate the laws of physics.  An easy but unpleasant way to violate said laws is to ask for more acceleration than the motor can achieve.  So how does one perform step motor trajectory calculations? As we learned in the post Dynamic Torque & Step Motor Sizing, maximum acceleration is determined by torque divided by inertia.
