Buy Small ERM Vibration Motors From A Manufacturer!
If you’re sourcing for ERM and LRA vibration motors manufacturer, Kegu-Motor is the right place. No agent fees, because we are the source manufacturers of small vibration motors. Eccentric rotating mass vibration motors are made of two parts, the brushed coreless DC motor and a eccentric rotating mass. This kind of motor have many advantages: high efficiency, low starting torque, low noise, it’s a kind of precision microdrives. When the coreless motor is mounted with eccentric rotating mass onto shaft, drive motor become vibration motor. The vibration force is depended on speed of the motor and the weight of eccentric mass. Generally the rated voltage is 1.5V, 3V DC. ERMs include coin vibration motors and pager motors, another small vibration motor is the Z-direction linear resonant actuators. All these three kinds for vibrator motor can provide sense of touch, however different form factors. When in supermarket, hearing loss, congenital disability, how to get vibrating alert? Use vibration feedback to replace sound remind is proper solution. This kind of vibration alert is most widely used in mobile phones and pagers. If you are in an important meeting, it can alert you in a more humanized way. Instead of a rough way through the loudly sound. When you receive a message or a call request, the vibrating reminder is an excellent way as a supplement the sound. Eccentric Rotating Mass Vibration Motor Working Principle The principle of erm vibrates like an incomplete fan blade. The motor uses a eccentric rotating mass to rotate at a high speed inside the mobile phone to generate vibrations. The eccentric wheel size used in the phone is very small. When the motor is rotating, eccentric mass will make a circular motion to generate centrifugal force. The rapid change of the force will generate vibrations. Cylindrical Vibrators (ERM type) also called pager motor that are always used for handle devices for vibration alerting. The pager motors rely on the rotation of an unbalanced load to create vibration effects. They are more recently being used for haptic feedback as well as vibration alerting. Our range of vibration motor’s have been developed primarily with communication application such mobile phones and pagers in mind. The range is widely developing to meet the demand for smaller, more powerful and low current consumption motors. ERM – Cylindrical Vibrator Motors Coreless Pager Cylindrical vibration motors are usually called pager motor, for in the early applications on pagers. And then started applying it to the phone for haptic feedback. Cylindrical vibration motor belong to the ERM(eccentric rotating mass) type. This is the weight found on rotating vibration motors to offer the vibration. This coreless vibration motor perhaps is the most common type that it’s uncomplicated and cost effective, the eccentric rotating mass is external visible and unprotected. The custom wire length is available for MOQ: 1k pcs, adding custom connectors for MOQ: 1k pcs, custom FPC is available for MOQ: 6k pcs, tooling & design fees will apply for custom FPC.
