C h a p t e r 1 | M o t o r T y p e s a n d T h e i r C o n t r o l C h a l l e n g e s speed and high torque. Additionally, because stepper motors do not inherently provide feedback, they are vulnerable to missed steps under heavy loads, which can lead to positioning errors. Hybrid stepper motors and advanced control techniques such as microstepping have been developed to address limitations around reliability, vibration, and audible noise and ensure a smooth motor run. On the other hand, a higher microstep resolution requires computational power for the step generation. Integrated motion controllers can unload software from this type of real-time critical tasks and significantly ease the generation of advanced motion profiles including positioning while eliminating software development, certification, and maintenance efforts. Microstepping allows for smoother operation and finer positioning control, while hybrid stepper motors combine the benefits of stepper and BLDC motors. The large variety of inexpensive stepper motors and inexpensive stepper motor driver systems makes them very popular in home, office, and lab automation. However, most inexpensive legacy stepper motor drive systems do not focus on energy-efficient operation, which makes stepper motors often run hot and have a low degree of efficiency. More advanced closed-loop servo control electronic systems rely on algorithms using a combination of current and position sensing to achieve effective motor control, as these two parameters are foundational for ensuring accurate, efficient, and reliable motor operation. Current sensing, which measures the electrical current flowing through the motor's windings, is needed to control torque, manage power consumption, and While selecting a motor control technique, start by looking at the type of industry and the specific needs of the application, like speed, tolerance, and torque. Consider safety features and whether an open or closed-loop system is best. Then think about quality, support, precision, efficiency, and other engineering capabilities needed for success."
