ESP32 is an upgraded version of the famous ESP8266 module developed by Espressif Systems. The newly added features like an additional core, faster Wi-Fi and, dual-mode Bluetooth (4.2 and BLE) made it preferable for IoT applications. Even today, many enthusiasts prefer this tiny yet powerful SoC (System on Chip) over other development boards. This article … Read more
ESP8266 is a low-cost SOC (system-on-chip) developed by Espressif microsystems. The unique feature of ESP8266 is that it lets you to connect to a 2.4GHz Wi-Fi network, using IEEE 802.11 b/g/n. Due to this feature, it finds applications in numerous IoT devices. Although it’s been a while since the ESP8266 made its debut, it is … Read more
Motor and generators are two of the most popular electrical machines used in an electrical system. There might be many differences between a motor and a generator, but their construction is almost similar. The main difference between a motor and a generator lies in energy conversion. While a motor converts electrical energy to mechanical energy, … Read more
There are three main synchronous motor starting methods: The first is by reducing the supply frequency, the second is by using an external motor, and the last is to start with damper windings. The external motor drives the synchronous motor shaft. It can either be a pony motor, a DC motor, or an Induction motor. … Read more
If we classify an induction motor based on the type of rotor used, there are two types of induction motor. The first is a Squirrel cage Induction motor, and the other is a Wound, aka slip ring Induction motor. Both these induction motors have a difference in their construction, starting, cost, and their application. This … Read more
There are four methods to start a squirrel cage induction motor. These are Direct On-Line (DOL), Stator resistance, Auto-transformer, and Star-delta starting, while for a slip-ring induction motor, we prefer rotor resistance starting. Now, you might think that an induction motor is self-starting, then why do we need induction motor starting methods? Right? Don’t worry … Read more
