THE APPLICATION & SOLUTION Vibration is not only used for haptic feedback, and user interface notifications. In this example, our customer is a manufacturer of bench-top pill and tablet counters. Some parts of their machines were being upgraded to handle larger quantities of pill and tablets, and
THE APPLICATION & SOLUTION Vibration alerting is a key feature for many applications. This is especially true when communication can mean life or death, such as an emergency services radio. But vibration alerting in this application is very different from a consumer cell phone. Firstly, the
THE APPLICATION & SOLUTION Many companies are developing intelligent consumer medicine dosing devices, which enables monitored patients to take correctly dosed medicines, at home. Previously this industry designed purely mechanical dosing devices such as insulin epipens. The challenge with pure mechanical devices, is that the
THE APPLICATION & SOLUTION Haptics is often associated with touchscreens, but in this application our customer introduced haptic feedback with a very different goal – to simulate the feeling of a patient’s heartbeat! Our customer is a medical company with the expected high requirements on
THE APPLICATION & SOLUTION Weather balloons are used to perform all kinds of experiments in the atmosphere. The balloon is filled with enough helium to reach the target atmospheric layer, and carries underneath it a small radio-controlled measurement lab. In this case study our customer
THE APPLICATION & SOLUTION Current robotics research is generating some very unique applications, and one particularly interesting field is ‘swarm robotics’. These applications seek to mimic the behaviour of simple creatures such as ants, where the ‘intelligence’ is observable at the swarm / group level. Our customer
Introduction We’re commonly asked for information such as MTTF (Mean Time To Failure), FIT (Failure In Time) or the total number of “cycles” that our DC motors and gearmotors will reach. This is a difficult question to answer as there are a variety of parameters
Introduction Cogging is an undesirable characteristic of some permanent magnet motor designs. It’s also known in stepper motors as ‘detent’ or ‘no current’ torque. Cogging torque is generated when the sides of the rotor teeth line up with the sides of the stator teeth within
Introduction At PMD we not only manufacture high-quality miniature motors and mechanisms, but we also design and make our own testing equipment. This means that we have a wide range of proprietary dynamometers, environmental and longevity testing equipment so that we can have confidence in the
This blog post is part two of a 2-part series. Part one was a quick re-cap of how LRA’s work and how they are driven by dedicated driver ICs. This part is about what happens when the LRA’s don’t work entirely as expected with selected
