In a similar post as our “Are your motors wireless?” article, here we’ll look at a common question we receive from those unfamiliar with electronics. We’re often asked if our motors are capable of providing vibrations for, say, 1 second then resting for 5 seconds. Again, the simplest answer is ‘yes’. This is because the timing function is not a feature of the motor, they turn when provided with a DC voltage and stop when the drive signal stops.…

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 applied in one direction is reduced. Due to the cyclical nature of vibration actuators (both ERMs and LRAs) high frequency vibrations only have a short period of time to displace the…

With our last post showing the haptic feedback test graphs for our Precision Haptic™ range, we can take a look at the performance enhancements achieved through these techniques. For a full discussion of the advantages of haptics, you may be interested in checking out these guides on our website: Haptic Feedback Overview Haptic Feedback and Vibration Alerting Integration Guide Again, we’re going to use the 305-000 haptic vibration motor as our reference, find the datasheet below:Time Reductions See the…

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, 6mm 306-109, and the 8mm 308-102 ERM vibration motors. The tests here are equivalent to the tests performed by Immersions in their TS2000 Actuator Performance Test. Download the 305-000 datasheet in the link below, the full test results are on…

We’ve all been working extremely hard on our upcoming Haptic Feedback Evaluation Kit that we announced back in December, ensuring that it offers you a high performance platform to experience haptic feedback. It will also offer a tremendous boost to the development process as you can immediately use it to start work on your own designs. Obviously, here at Precision Microdrives we’re really excited about it, and we’re happy to see that it has been the subject of many…
