This HEW DCEx 71KH/2K is an explosion-protected three-phase electric motor intended for industrial installations where electrical equipment requires certified protection for potentially explosive gas atmospheres.
The motor has a rated mechanical output of 0.37 kW and operates from a 50 Hz electrical supply. At its rated operating point, the motor runs at approximately 2855 rpm, identifying it as a high-speed 2-pole motor configuration.
The motor is designed for dual-voltage operation. It can be connected in delta at 230 V with a rated current of 1.61 A, or in star at 400 V with a rated current of 0.93 A. The stated power factor is cos φ 0.77.
The enclosure is rated IP55, providing protection against dust ingress and water jets. The winding insulation is specified as Class F, making the motor suitable for demanding industrial duty within the manufacturer's specified operating limits.
The motor carries ATEX certificate number BVS 14 ATEX E 114 X and is marked II 2G Ex db eb IIC T4 Gb. This identifies the motor as explosion-protected equipment for gas-hazardous environments, with protection concepts including flameproof and increased-safety construction. Suitability for a specific hazardous zone, gas group and installation must be confirmed against the complete plant requirements.
The identification plate also references the IEC/EN 60079 series of standards and carries CE marking together with notified body number 0158.
Electrical cable entry is provided through 4 x M20 x 1.5 entries, allowing connection of the motor and associated hazardous-area cable glands as required by the installation.
This type of explosion-protected motor is suitable for driving pumps, fans, mixers, gear units and other industrial machinery installed in areas where certified Ex electrical equipment is required.
