Considering the trade offs of different fan bearing designs

Considering the trade offs of different fan bearing designs
Fans are a vital element of many electronic systems, designed to keep the device operating within recommended temperatures, while making sure the electronics are working at their optimum level. Attempts have been made to find alternative thermal management methods, with none proving as effective and economical as the fan.

Understanding the encoder resolution

Understanding the encoder resolution
An incremental rotary encoder can be used to measure rotational direction, speed and angular displacement. The encoder generates two output channels as it rotates, A and B. Each output is a square wave, and in a quadrature encoder, the two outputs are 90° out of phase. By Jason Kelly, Motion Control Design and Applications Engineer, CUI.

Encoder output choices for best performance and signal integrity

Encoder output choices for best performance and signal integrity
Motion control applications typically require one or more position encoders. Several types are available and the engineer must first decide whether an incremental, absolute, or commutation encoder is most appropriate. After this decision has been made, other selection criteria include resolution and mechanical aspects, such as the mounting pattern and motor shaft size.  By Jason Kelly, Motion Control Design and Applications Engineer, CUI

AC-DC efficiency measurements need to include power factor

AC-DC efficiency measurements need to include power factor
Power converter designers compete to minimise losses, chasing the last decimal points of efficiency, η, the ratio of output to input power. But when it comes to calculating efficiency in AC-DC power supplies mistakes are often made as a result of omitting or improperly measuring power factor, which is why it is important for designers to understand power factor basics and how to incorporate it.
