We’re seeing a great number of startups and early projects looking for design advice. In part this is thanks to advancements and cost reduction in 3D printing, but also the general adoption of crowdfunding has provided small companies and individuals with more opportunity to get
Introduction If you are looking to run more than a single motor from a driver or MOSFET you may be concerned with the additional power consumption and exactly what happens in the circuit. We’ll look at series and parallel connections, highlighting what this means for drivers. In addition, there’s
Introduction Just as with other components in your system it is important to profile vibration motors, in particular, to test its strength or frequency. Our specialised facilities allow us to quickly and easily run a variety of tests to fully analyse the performance of the motor
We are delighted to announce our Haptic Feedback Evaluation Kit has been made available through our product catalogue. If you are unfamiliar with the kit, it is a tool for people to experience haptic feedback and compare it to vibration alerting. It includes our Precision Haptic™ actuators so
The harder you strum a guitar, the more you feel it vibrate. Similarly, kick a bass drum pedal and you’ll feel a definite tactile response as the mallet strikes the drumhead. Increasingly, musicians are using computers in their live performances – sometimes as instruments in
DC motors don’t just produce electrical noise, they can also create audible noise. The perceived level of noise is extremely dependant upon the motor’s environment. For example, in an anechoic chamber, the sound of a motor running (or any noise at all) would appear very loud,
So how does a vibration motor cause an entire object to vibrate? For eccentric rotating mass vibration motors, the unbalanced force created causes the motor to displace. The displacement is very small because the motor rotates so fast (the direction of the force changes as the
Is there an ideal frequency for vibration alerting or haptic feedback? Different nerves in our skin are more sensitive to different frequencies, but generating vibrations at these frequencies may not be quite so simple. As the vibration frequency increases, the duration of time for the force to be
As promised in December, our Precision Haptic™ range now includes three ERMs in addition to the two existing LRAs. In this blog post, we are explaining the new graph that appears on the datasheets for the 5 mm 305-000 (since depreciated), 6mm 306-109, and the 8mm 308-102 ERM vibration motors.
Those looking for the Quick Vibe Estimator will find the tool in AB-031: Vibration Motor Calculators – ERMs and LRAs Our vibration motors and linear resonant actuators use the unit G to describe their vibration amplitude. It leaves some of our customers with the question exactly what is G?
