Operation of vacuum stepper motors
Posted on Friday 2nd July 2021 at 10:00
Stepper motors are typically digitally controlled using a stepper motor drive and can’t be driven in the same manner as a conventional AC/DC universal motor. They are the main components in open-loop motion-control positioning systems as they are capable of achieving clearly defined rotational positions, speeds and torques making them ideally suited to tasks requiring highly accurate and precise movement control. Our vacuum compatible stepper motors share the same basic operating principle... Read more

UHV-Compatible Custom 4-Axis Manipulator
Posted on Wednesday 28th October 2020 at 11:13
Arun Microelectronics specialises in the design and manufacture of in-vacuum motion systems and is a leading global manufacturer of vacuum compatible stepper motors for industrial, scientific and R&D applications. A customer contacted us requiring a UHV-compatible 4-axis manipulator for an electron beam application. We worked closely with the customer to design a custom manipulator stage. The travel and load parameters were provided as well as some other key design requirements. &nbs... Read more
How an AML UHV-compatible stepper motor is made
Posted on Monday 12th October 2020 at 10:00
AML stepper motors are used in ultra-high vacuum systems that require in-vacuum object manipulation. They are specifically designed to eliminate trapped volumes and are manufactured using only UHV compatible materials. The motors are assembled using UHV-compatible methods, in a dedicated cleanroom at our factory in the United Kingdom. All motor components are initially cleaned using UHV compatible processes and are vacuum conditioned at elevated temperatures, before amorphous carbon surface tre... Read more
