Stepper motors are brushless DC motors that are widely used in motion control devices such as linear actuators when precision motion is required. They have emerged as cost-effective alternatives for DC servomotors in several applications ranging from machine tools, medical equipment, to computer peripherals and automotive devices, among others. A stepper motor-based linear actuator, which uses a stepping motor as the source of power, is widely recognized as a cost-effective and reliable motion solution. Trends towards miniaturization and cost reduction immensely contribute to the wide acceptance of the quieter, more efficient and durable stepper motor-based linear actuators. What else adds to their popularity for applications demanding high performance and exceptional endurance in a very small package? This post discusses the same in brief.
