Motors efficiency ratings

The efficiency of an electrical motor is the ratio of mechanical power output to the electric power input. IE = International Efficiency : IE1 (Standard Efficiency) IE2 (High Efficiency) IE3 (Premium Efficiency) IE4 (Super Premium Efficiency)

Ingress Protection (IP) and what it means

Ingress Protection (IP) and what it means   The IP Code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating*) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms [...]

What is the Fan Characteristics Curve ?

Fan Characteristic Curve stands for the relationship between volumetric flow rate and the pressure drop across the fan (static pressure), which is described by the fan characteristic curve. It is usually provided by the fan manufacturer. Below table shows a characteristic curve for a common tube-axial fan for instance.  

Types Centrifugal Fan,Axial Fans and Common Blower

 The major types of centrifugal fan are radial, forward curved and backward curved. Radial fans are industrial workhorses because of their high static pressures (up to 1400 mm WC) and ability to handle heavily contaminated airstreams. Because of their simple design, radial fans are well suited for high temperatures and medium blade tip speeds. Forward-curved fans are used in clean environments and operate at lower temperatures. They are well suited for low tip speed and high-airflow work – they are best [...]

Difference between Fans, Blowers and Compressors

Introduction Fans and blowers provide air for ventilation and industrial process requirements. Fans generate a pressure to move air (or gases) against a resistance caused by ducts, dampers, or other components in a fan system. The fan rotor receives energy from a rotating shaft and transmits it to the air.   Difference between Fans, Blowers and Compressors     Fans,  blowers and compressors are differentiated by the method used to move the air, and by the system pressure, they must operate against. As per American  Society [...]
