App note: Vibration motor best practices from mobile/cell phones
App note from Precision Microdrives on how to design drivers for vibration motors on battery powered mobile devices. Link here The mobile phone industry is a huge market in which vibration motors are an established component. Now almost every device has the ability to produce vibration alerts and the field of haptic feedback is rapidly […]
App note: Experiments in waterproofing / Overmolding vibration motors
App note from Precision Microdrives experimenting on which is the best method to waterproof their vibration motors. Link here We have mentioned some interesting vibration motor applications which may benefit from being waterproof or water resistant. For example, performance indicators for athletes, or stroke rehabilitation gloves would require regular cleaning. Naturally, the most convenient method […]
App note: Driving brushless long-life vibration motors
App note from Precision Microdrives on new brushless motor design and how to drive them efficiently. Link here For a long time, all motors driven by DC supplies relied on using metal or carbon brushes to provide electrical power to the motor’s internal components. Meanwhile, in larger motor designs it has also been possible for […]
App note: Securing vibration motor leads and wires
App note from Precision Microdrives on how to properly connect wires on to vibration motors for reliability. Link here Vibration motors require electrical power, which must be delivered by wires or PCB tracks to the motor. Precision Microdrives vibrating motors are available in a range of connector forms. From stock, they are available with factory […]
App note: Vibration Motors – Voltage Vs Frequency Vs Amplitude
All about vibration motors and how its frequency and amplitude be controlled in this app note from Precision Microdrives. Link here We’re often asked how to adjust the vibration amplitude or frequency of our various vibration motors. In this article, we’ll look at how simple it is, why it can be useful, and how we […]
App note: Lifetime of DC vibration motors (MTTF & FIT)
DC vibration motors failure analysis by Precision Microdrives. Link here Reliability is an important consideration for engineers and product designers. It is also very context specific. For example consider a car, which is made from lots of individual components. If the radio antenna should fail, the car still operates. However this is not the case […]
App note: Driving linear resonance vibration actuators
Linear resonance vibration actuators are great alternative to Eccentric rotating mass (ERM) motors, these are both used to vibrate handheld devices such as cellphones, driving LRAs is not the same as driving ERMs for such that LRA needs a specific resonant frequency. More on these on Precision Microdrives’ link here. Linear Resonance Actuators (LRA) use […]
App note: Mechanical mounting for vibration motors to bulkheads
Vibration motor bulkheads mounting guide from Precision Microdrives. Link here The word bulkhead has a few different meanings, in this context we are using it to represent a large flat surface or sheet. For example, a large metal chute which is carrying materials which are prone to coagulating, may require a vibration motor. This bulletin […]
App note: Mechanical mounting for vibration motors to PCBs
Vibration motor PCB mounting guide from Precision Microdrives. Link here There are many methods for mounting a vibration motor to a Printed Circuit Board (PCB), each with their own advantages and disadvantages. Some techniques are specific to different types of motor. This guide will help you evaluate different mounting methods and perhaps introduce some options […]
