Explosion-proof Electro Adda PE-Ex-de engines

Three-phase asynchronous electric motors with a closed-loop rotor manufactured by the company Electro Adda The PE (Ex-de) series are equipped with an explosion-proof housing made of high-strength steel, a rotor made of copper alloy and additional protection by a box terminal. The winding is impregnated with resins in vacuum, according to VPI technology, and additional insulating materials based on polyester or fiberglass are also present in the electric motor. The design of the electric motor is dynamically balanced, the shaft is cylindrical (steel grade C45), keyed connection. To protect against thermal shock, electric motors are equipped with thermal sensors, and an automatic switch is also provided for critical indicators. Considering the technical advantages of electric motors of this series, the company Electro Adda It positions them as explosion-proof, since they were designed for safe operation in areas with a high probability of explosion (explosive atmosphere, risk of explosion spread, sources of ignition).
