The differences between the 3 main types of sensors for three-phase motors: capacitive, inductive and barrier. Learn how to choose the ideal sensor for your application. Have you ever had to connect a three-phase electric motor? Probably yes, but what about using a capacitive sensor, or an inductive sensor, or even a barrier sensor (photo sensor), to activate the three-phase motor? In this video, we will talk about the three most common types of sensors for three-phase motors, and how to choose the right one for your application. 1. Capacitive sensor Capacitive sensors work by measuring the change in capacitance of an electric field. They are often used to detect nearby objects, such as a motor that is about to hit a barrier. 2. Inductive sensor Inductive sensors work by generating a magnetic field and measuring the change in inductance of a circuit. They are often used to detect metal objects, such as a motor that is about to come into contact with a ferromagnetic object. 3. Barrier sensor (photo sensor) Barrier sensors work by emitting a light signal and measuring the reflection of the signal. They are often used to detect solid objects, such as a motor that is about to collide with an obstacle. Choosing the right sensor to drive a three-phase motor depends on a number of factors, including the type of object to be detected, the distance to be detected, and the environment in which the sensor will be used. #### Link Commented in the video #### http://eletri.co/d021023 ????????
