he so-called Hermetic Motors type is a structure in which the air around the motor does not circulate with the internal air of the motor and has a closed shell. It has the characteristics of preventing the intrusion of harmful substances from the outside, hermetic motor comprises only a wound stator and squirrel cage rotor, without any shaft bearings or motor housing of its own. According to the new market research report “Global Hermetic Motors Market Report 2023-2029”, published by QYResearch, the global Hermetic Motors market size is projected to reach USD 3.07 billion by 2029, at a CAGR of 3.3% during the forecast period.

This Ppt shows what is air handling and what kind of equipments are generally employed for air handling applications and Explain the different terminology related to air handling like pneumatic conveying, central vacuum cleaning, roots blower, roots compressor, vacuum booster, vacuum pump, dust collection, aeration in storage silos, dewatering and air drying. Visit http://www.acmeairequipments.com/company-profile.html to more information about air handling terminology. An air-handling unit is generally used for circulating and transporting air. It involves the use of squirrel cage blower powered by an AC electric motor to circulate the air. Vanes are used to control the rate at which air flows within. Air handling equipments operate through the principal of circulating and conditioning airflow through cooling, heating and ventilating units. The units are connected to a duct, which distributes air throughout the building unit.
Induction motors are simple and rugged in construction. They are used in most of the industries. The advantages of induction motors include their robustness and ability to operate in any environmental condition. DC motors which were earlier used for industrial applications have now been replaced by induction motors.
