coin vibration motors, also known as shaftless or pancake vibrator motors, generally in Ø8mm – Ø12mm diameters for our range. Pancake motors are compact and convenient to use. 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.

Voice coils were originally developed for loudspeakers for the conversion of electrical energy into sound waves through the use of a diaphragm. Loudspeakers were used to amplify or create a louder voice; thus the name “voice coil.” Today they are called audio speakers, and their ability to achieve the desired frequency response is where this technology excels. Voice coil actuators (VCAs) use similar technology to speakers, but they are designed to produce higher forces over a larger distances or strokes. The increased force and stroke capability does come at a price with regard to frequency response, i.e. most voice coil actuators do not operate above 200 Hz unless the stroke is extremely small (.5 mm or less).  Linear Voice Coil Motor Micro Rectangular Magnets N30H

Since their inception, VCAs have found wider use in applications where proportional or tight servo control is necessary. By virtue of their high acceleration, VCAs offer numerous advantages in applications such as medical valve actuators, semiconductor manufacturing Z-axis applications, and instruments used in spectroscopy and chromatography. In VCA applications where position accuracy is important, position resolutions are only limited by the position feedback device and control electronics, not by the VCA itself. With control electronics and feedback sensors, VCAs can perform a wide variety of motion profiles. They can accelerate quickly then come to a gentle stop at a very precise position. They can also push with a precision amount of force in both directions. High-speed wire bonding is a good example of an application where VCAs are used in a high-speed position loop. Voice coil actuators are ideal for life and stress testing applications.  Cell Phone Vibration Motor Coin Type Magnets N40
