 Q - coin vibration motor

 

We currently produces coin vibration motors, also known as shaftless or pancake vibrator motors, generally in φ8mm - φ12mm diameters coin vibration motors. Pancake motors(disc motor, pager motor) are compact and very convenient to use for any haptic feedback (force touch) applications. They integrate into many designs because they have no external moving parts, and can be affixed in place with a strong permanent self-adhesive mounting system.

 

Enclosures can easily be moulded to accept the coin form of our shaftless vibration motors. Within the coin motor range, we offer both leaded and spring & pad mountable versions. Like all of our vibration motors, we are happy to quote for variations to the base design such as a modification to the lead length and also connectors.

 

 Micro ERM vibration motor

 

Need-For-Power Electric DC Motors, the leader in global micro vibration motors supplier, offering custom engineering solutions based on a wide range of low voltage DC vibrating motor platforms. We have developed technical expertise particularly in ERM miniature vibration motors and linear resonant actuators (LRAs) used for haptic / tactile feedback and vibration alerting. Our understanding of vibration actuation is relied on by customers worldwide in handheld, medical, automotive, massaging and mechanical-aid applications. pmdc motor manufacturer, pmdc motor working.

 

We carry a wide range of products with a variety of frame sizes from as small as ˜4mm for same-day dispatch. We produce customised and high volume demands to order and frequently modify our base (stocked) parts upon request.

 

 Linear resonant actuator LRA

 

Within our Precision Haptic range of vibration motors, we offer several types of Linear Resonant Actuator (LRA) vibration motors (also known as linear vibrators) such as ELV - 1030A, ELV - 1036A. LRA motors are different to Eccentric Rotating Mass (ERM) vibration motors in the way that they work theory and how long they can last their lifetime in your wearable feedback application.

 

When you have an application that requires a low power consumption, high amplitude, our Linear Resonant Actuator (LRA) vibration motors as an alternative to long life brushless vibration motors is your best choice. However, please understand that such longer lifetime and control does come at a slightly increased cost of complexity.

 

Linear vibration motors are an excellent choice for haptic feedback applications requiring a device with high reliability and exceptionally long life. Compared to traditional ERM vibration motors, LRA’s are a superior choice for haptic applications due to their faster rise / fall times. Vibration energy is generated by an internal mass that oscillates back and forth along one axis at its resonant frequency.

 

Our LRA’s are designed to have a resonant frequency / vibration frequency in the 205 hz range which research has shown to be optimal for the nerve receptors of the skin. LRAs are an excellent alternative to brushless vibration motors as the only internal parts that are subject to wear and failure are its internal springs. Unlike conventional brushed DC vibration motors, linear resonant actuators must be driven by an AC signal at the devices resonant frequency. A number of companies make haptic IC drivers for linear vibration motors that supply the correct AC drive signals and contain a library of haptic effects you can choose from. These driver ICs also provide over drive and braking signals to the vibration motor which further improves rise and fall times thus providing a superior haptic feedback experience for the user. Unlike brushed ERM vibration motors, varying the amplitude of the applied voltage will only change the amplitude of the vibration force, not the frequency of vibration. The frequency of vibration is fixed at the LRA’s resonant frequency. Due to the LRA’s Hi-Q, applying a frequency above or below the resonant frequency of the LRA will result in the LRA producing a lower vibration amplitude or if far from the resonant frequency, no vibration at all.

 

We can produce following models with a quite cheap price compare to PMD (No middleman profits).
