All kinds of mechanical systems use a critical component commonly known as an encoder. Large industrial machines performing delicate work, high-precision prototyping, or repeatable tasks use encoders predominantly. Production of advanced electronics also requires the use of encoders. Encoders can be linear, angle, or rotary and the electronics sector uses them in some form or the other. Semiconductor fabrication, with its small components and work areas, requires encoders of the highest resolution Read more [...]
All closed loop systems use feedback to control speed and or position. This plays an important role in keeping equipment operating accurately and smoothly. When using feedback for the best benefits in an application, it is important to understand how feedback works, because a variety of devices as well as models is available for the purpose. The most popular among them are tachometers, Hall sensors, encoders and resolvers.
Tachometers are rotating electromagnetic devices. Typically, Read more [...]
