A Huge Thank You and Temporary Pause of our Tech Blog

  • 3 February 2016
    • A huge thank you to all our subscribers!
Around 5 years ago we started keeping a regular blog on our site. We thought it would be useful resource for customers, providing short articles that helped answer frequent questions or notifying people about our larger Application Bulletins. As more questions and comments about the articles on the blog came in, we wondered if people would like to have the content delivered straight to their inbox. So at the start of 2012 we sent our first email to a…

Are DC motors reversible?

  • 30 December 2015
    • Fleming's left-hand rule shows the direction of force on a current carrying wire in a magnetic field
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 haptic feedback, make use of ‘braking’ to control the motor without it actually turning in the opposite direction. If a motor is already in motion, the applied voltage can be inverted and…

Which haptic effects should you use?

  • 16 December 2015
    • What is the difference between haptic effects?
Haptic feedback is all about transmitting information to the user, often they are required to tell the difference between the multiple types of notification. This is where we enter the world of human factors engineering, or ‘ergonomics’. This is the discipline that considers how humans interact with other elements of a system and designs accordingly. For example, have you ever considered why the numbers on a calculator keypad are the opposite way from a phone’s keypad (#1 is in…

Tachometers vs Encoders - What's the Difference?

  • 3 December 2015
    • Tachometers provide information on speed, but encoders provide the position
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 are a wide-range of complex encoders available, but a simple tachometer will often get the job done. But first, let’s look at what each device does. In short, both tachometers and encoders are designed to provide some information about the…
