Programmable source powers dc micromotors

摘要

The circuit in Figure 1 is a simple, economic, compact, and tricky way of using the LM723 as a programmable voltage source to drive dc micromotors. Because of the μPs' accurate positioning and control, these motors are useful in applications such as optical mounts and flexible shaft control, which take advantage of the higher speed and fast movement of servo controls compared with stepper motors. These designs require a stable, programmable dc-voltage source.
