Product Profile of Industrial Ac Flame Proof Motors

New bharat electricals brings ac flame proof motors. The company is the manufacturer and exporter of all types of electric motors like a.C motor ,d.C motor, pumps, gear motors, gear boxes, agriculture machineries, machine tools. The flame proof ac motors are designed to serve the industries such as refineries, coalmines, and petrochemical industries etc, where inflammable gases, vapors, fumes and coal dust are natural atmospheric hazard. The flame proof enclosures are made of sturdy cast iron parts to resist any internal explosion. The flame proof ac motors are compact in construction, lightweight, attractive appearance, safe and reliable operation life, good performance and easy maintenance. These flame proof ac motors are applicable for environments, such as outdoor location, indoor tropical humidity, outdoor tropical humidity, indoor tropical arid, outdoor tropical arid, indoor tropical, outdoor tropical and outdoor middle class chemical corrosion locations. Some construction features of this flame proof ac motors are as follows:

• The flame proof construction for exd,

• The degree of protection is ip 55 for motor main enclosures.

• The stator winding are of class f insulation and gives a large margin of safety in temperature rise and long service life.

• The stator winding are wound with polyester enamel round wire of high strength and treated with the progress of vacuum-pressure impregnation to make them solid. The winding insulation is good in electrical and mechanical properties, moisture resistance and thermal stability.

• A cylindrical shaft extension is furnished on motors that can be driven by coupling or spur gearing

• The rotors are of cast- aluminum and dynamically balanced to make the motor operate smoothly with small vibration and the low noise.

• The motors are fitted with low vibration and low noise bearings. The bearings are the with both side seals. The drive end bearings are per-loaded with special pre-loading wave washers to restrain efficiently the vibration and noise produced during working condition.

• Fans are made of cast iron, and have low wind age loss.

• The stator and rotor cores are laminated with high class electrical steel sheet with high permeability and the low loss, making the motors to posses low loss and high efficiency
