Coin Vibration Motor :: Pico Vibe™ Range

Overview

Precision Microdrives’ currently produces coin vibration motors, also known as shaftless or pancake vibrator motors, in Ø8mm and Ø10mm diameters for our Pico Vibe 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 very strong permanent self-adhesive mounting system.

Enclosures can be easily moulded to accept the coin form of the 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.

Applications

Due to their small size and enclosed vibration mechanism, coin vibrating motors are a popular choice for many different applications. They are great for haptics, particularly in handheld instruments where space can be at a premium:

• Mobile phones,
• RFID scanners,
• Industrial tools or equipment user interfaces,
• Portable instruments,
• Medical applications.

Design

Our coin or pancake vibrating motors are all Eccentric Rotating Mass (ERM) motors. Therefore they can be driven in the same manner as their pager motor counterparts. They have the same motor drive principles, including H-bridge circuitry for active braking.
