Using 3V vibration motors

[iyermihir]

I want to use this vibration motor with a voltage rating of 3V and a voltage range of 2.7 ~ 3.3 for a project. Is it okay for me to use the motor with this voltage regulator even though the regulator outputs 3.3V?

Item 2-2 in the vibrator datasheet is the operating voltage, which is 2.7-3.3v.
Item 4-3 in the vibrator datasheet is the starting current, which is 120mA.

Voltage doesn't look like it's a problem, and current draw at the start doesn't look like it's a problem for that particular voltage regulator.

Keep in mind you'll be working with an inductive load, so if you have any switching on the motor you'll want to have a flyback diode.


Hope this helps.
