Pololu item #: 1638
Brand: Unspecified
RoHS 3 compliant


This tiny, button-type, vibrating motor shakes with a vibration amplitude of 0.75g and draws approximately 60 mA when 3 V is applied to its leads. The shaftless design keeps this motor small: 10 mm in diameter and 2.0 mm in height.

Overview

This shaftless vibration motor is fully-enclosed with no exposed moving parts. Its small size (10 mm diameter, 2.0 mm height) and shaftless design mean you can mount it on a PCB or even place it in a pocket to add quiet, haptic feedback to your project. The motor has a 3M adhesive backing on it for easy mounting and 1.5" leads for making quick connections. Polarity is not important; the motor can run CW or CCW.

We offer this vibration motor in three different sizes:

All three of these motors have the same vibrational amplitude (0.75g), but the 10×3.4mm version has more mass than the other two, which results in a slightly greater vibrational force.
