Epoxy-based Hermetic Feedthroughs Boost Switchgear Reliability

With medium-voltage switchgear, progress is being made with regard to finding alternatives to SF6 as an insulation gas. Designs that incorporate dry air or a mixture of fluoroketone, nitrogen and oxygen as the insulating gas are being explored to minimize environmental impact.

How to Prevent Step Losses with Stepper Motors

While stepper motors are an excellent solution for many applications, a key concern is step losses. However, in most instances step losses can be prevented or corrected. It is important to remember that a stepper motor does not operate like a DC motor. This white paper from MICROMO engineers provides guidance to determine step losses or non-operation across a variety of applications.

Integrated Epoxy Feedthroughs Improve Fuel Pump Reliability

Of all the design decisions that affect the operation of an in-tank fuel pump, the way you seal the pump housing may top the list. A bad seal will allow liquid fuel to work its way into the housing, which will eventually corrode the electronics and potentially cause a risk of fire.
