Hazardous area electric motors

TECO has unveiled additional models to join its established range of MAX-E design electric motors. Like the rest of the MAX-E range, the new motors meet the stringent International Electrotechnical Commission safety standards for electrical equipment used in hazardous areas.

New TECO electric motors are available from 0.18kW to 450kW on a short lead-time or up to 560kW on a build to order basis. These complement the existing IEC Ex certified TECO MAX-Ex de range of flameproof stock motors.

Certification available

The new low voltage series is IEC Ex certified from frame sizes D71 up to D355 with certification also available in the following hazardous areas:

• TECO MAX-Exe; increased safety

• Exe e, Zone 1, Gb, IIC, T3, 40°C ambient to IECS60079.7: 2006-2007

• TECO MAX-ExnA; non sparking

• Ex nA, Zone 2, Gc, IIC, T3, 55°C ambient to IECS600795: 201D

• TECO MAX-ExtD; dust ignition proof

• Ex tD, Zone A21, T135°C IP66, 55°C ambient to IECS614241.1: 2004

• Certificate Nos: IEC Ex TSA12.D016X, TSA 12 0017X, TSA12.0018X

Whether modified in Australia, or supplied direct from TECO’s factory in Taiwan, TECO can now adapt the MAX-E2 or the latest MAX-E3-H66 Premium High Efficiency, Class H insulated, IP66 mining duty motors to meet the safety requirements of most hazardous areas.

Meets numerous applications

The MAX-Ex range of stock motors can be modified to meet numerous application specific requirements including foot (B3) or flange (BS-B14) mounting options, auxiliary protection such as thermistors, RTD’s for stator or bearing temperature monitoring, anti-condensation heaters, separate terminal boxes for accessories, or even special paint finishes.

High efficiency

With the addition of the MAX-Ex hazardous area motors, TECO now offer a complete range of electric motors combining the highest levels of environmental safety with the lowest possible running costs. With a proven and sophisticated electromechanical design and high efficiency, the MAX-E3-H66 range is perfect for the rugged conditions required by the Australian mining sector and other demanding applications.

TECO Australia supplies a complete range of electric motors, variable speed drive systems and motor controls for all industries.
