Vibration Motor Family Includes Brush And Brushless Versions

A family of brush and brushless dc vibration motors are aimed at a wide range of applications. The 10-mm diameter coin-shaped devices include the brushless dc vibration motors: the LBV10L at 3.4 mm (0.134”) thick, the LBV10B at 3.0 mm (0.118”) thick, and the slimmer LBV10C at 2.35 mm (0.093”) thick. Excitation voltage is a universal 3.0 Vdc. These higher-performance brushless dc coin vibration motors are used in many critical medical instrument applications, including insulin pumps and embedded defibrillators. The more cost-effective brush dc coin vibration motors are available in two frame sizes. The 10-mm diameter by 3.0-mm (0.118”) thick LAV10 consists of two models: one with a 2.0-Vdc input for PWM input signals and the other with a standard 3.0-Vdc input. Typical applications include force feedback systems. The larger 12-mm LAV11 diameter by 6.1-mm (0.240”) thick brush dc coin vibration motor is used in handheld games and other applications with higher load requirements. Using only 24 mA at 3 Vdc makes these motors ideal for applications where minimal current draw is critical. Some of the models are available with rubber boots and specified connectors.
