Vibration motor with electric actuator

The primary function of the vibration motor is to alert the user to incoming calls. Vibration motors are normally classified into cylinder type and button type. Here, we will look at how the cylinder type works. Coreless Motors A coreless motor is a DC motor with a rotor that does not have an iron core. Instead, it has a permanent magnet inside and a coil outside. Eliminating the iron core from the rotor offers the following advantages: Smaller rotational inertia and faster Smoother rotation due to absence of magnetic
