Miniature Motors for Valve Actuation

Posted by Anant Bhalerao   Jan 27, 2016   4 Comments

An expansion valve is a flow-restricting device present in a refrigeration system that causes a pressure drop of the working fluid. The valve needle remains open during steady-state of operation. The size of the opening or the position of the needle is related to pressure and temperature of the evaporator. When set and controlled properly, an expansion valve will keep the evaporator active throughout its operation.  There are two types of electric expansion valve technologies popular in the market place - pulse width modulated valves, and stepper motor driven valves.

Miniature Motor Driveline Solutions for Aerospace Applications

Posted by Jigar Fulia   Oct 15, 2015   0 Comments

The technology world is rapidly adapting to miniaturization, with terms like “Micro”, “Nano” and even “Pico” increasingly in vogue. This has created an immense need for anything that can provide packaged products in smallest possible sizes, and miniature motor solutions play a critical role in addressing this need. With a growing number of applications, these motors now need a wide range of capabilities, from working in a simple office to functioning in extremely hazardous environments. An application demand from Aerospace & Defense (A & D) industry falls in the latter category. Stepper motors play an important role for any A&D application need that requires some precise positioning.
