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
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
Recently we had a few customers asking about driving our DC gear motors with H-bridges, and specifically, whether they would need additional fly-back diodes for each transistor in the bridge. As it happens – you don’t, and there are a few options that can be
Incremental encoders are used in many different motor applications, where they can provide information on the motor’s speed or the shaft position. Normally, the output signal from an encoder is at least one square wave, but most often it sends two square waves with their
Simply put, DC motors can turn in either direction (clockwise or counter-clockwise) and can be easily controlled by inverting the polarity of the applied voltage. Strictly speaking, the motors can actually create a force in either direction. We make this important distinction because some applications, such as
As it is possible for tachometers to perform the same basic function as encoders, it’s common to find that sometimes there is a bit of confusion between the terms. This can often lead to ‘over-design’ or ‘over-engineering’ because there is a wide range of complex
As our testing machines and capabilities have grown over the years, we’ve been able to offer more and more complicated customisations to our customers. So to help handle some of these enquiries and manage expectations, we’ve put together some content that answers many of the
Something we have discussed in the past is how varying the voltage to a vibration motor can change the amplitude, particularly with reference to haptic feedback and playing different effects. However, something we haven’t explicitly shown is why this happens, or discussed it in the
You may have noticed a recent change on our datasheets and in some sections of our website, relating to how we qualify our DC motors and gearmotors. The previous value of ‘Rated Torque’ has been replaced with ‘Rated Load’ (see bottom left in the image
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
