Is your Step Motor and Driver Contributing to the Inaccuracy of Your System?

Getting all components of a system to function together like a finely tuned engine is a long and exhausting process. There are many reasons why all components will not work in harmony. This paper discusses the issue of inaccuracy in a system and indentifies the two main culprits: the step motor and the driver.

Adhesives Enable Innovative Improvements in Stepper Motor Performance

Stepper motors are some of the most sophisticated motors used in the most challenging applications today. They require high step accuracy, high resolution and smooth motion all in a very compact size. In addition, stepper motors must often be customized to achieve optimum performance in a specific application. This paper discusses how the use of Loctite adhesives has helped increase quality and reduce cost in the manufacturing of Lin step motors.

R-Winding

Most step motor users are familiar with Series and Parallel connections; now, the patented R-Winding (U.S. Patent No. 6,969,930) has been created to reduce noise and vibration for lower-torque applications.

Step motors typically run with a driver that either half steps or full steps. For example, a 1.8° stepper, one step will be 1.8° if set to full stepping or it will be 0.9° if it is set to half stepping. Looking closer at the electrical phase changes during half stepping, a typical sequence is to turn on, or give full current to, the A phase. Next, both A and B phases will be turned on, then A will turn off and only B will turn on, and so on. When only 1 phase is energized, we define this as the 1-Phase ON position. The chart below shows the sequencing process to make a motor turn.

Step Motor Accuracy

Often times when an engineer is selecting a step motor for his or her application, one important decision that needs to be made is whether or not to choose a 0.9° or a 1.8° step motor. When making a decision of this magnitude, two factors will invariably come into play: performance and price. With the ever increasing role of competition in today’s motion control industry, both performance and price are major difference makers in every decision.
