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 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
The Concept Recently we were contacted by the GravityLight™ team regarding a very interesting project they are working on, an alternative to kerosene lamps that is powered only by gravity. Kerosene lamps are still commonly used in the developing world, despite the numerous financial and
What makes brushless vibration motors long life? The clue’s in the title! The precious metal brushes are typically the most common source of failure that limits the lifetime of normal DC motors. They are integral to the operation of our eccentric rotating mass vibration motors in the ‘Vibration Motor’
Most questions we are asked are answered somewhere in our datasheets or on the website, and we’re more than happy to help our customers with all the information you need. Unfortunately, the answer to one of the most common questions is not to be found. “How long do your motors
At Precision Microdrives we believe our vibration motor in-house testing is second to none. We want to produce accurate and informative datasheets to help our customers understand our products, whilst ensuring our quality control is of the highest standard. It is this mentality that helped earn
