Although motion control specialist, Huco Dynatork has been actively broadening the scope of its power transmission range, the company is strategically populating it with many products that have distinct design and performance benefits over others on the market. Its AC motors are typical examples and currently include motors with integrated frequency converters, waterproof motors and motors without ventilation.

Falling into the same category is a new series of ATEX motors for use in explosive atmospheres. These aluminium bodied, induction motors are available for operation in Zones 1, 2, 21 or 22.

The EX models designed for operation in gas laden atmospheres are available as ‘increased safety’ and ‘non-sparking’ versions, respectively for ATEX categories 2G and 3G with EX e and EX nA protection. Choices include single or three phase and single or two speed motors with outputs of between 0.06 to 18.5kW.

The needs of ATEX categories 2D and 3D for safe operation in the presence of explosive dust are met by a similar range whose versions either provide ignition protection from conductive dust – EX tD A21 IP65 – or ignition protection from non-conductive dust – EX td A22 IP55. They too may be specified as single or three phase, single or two speed units and with outputs of between 0.06 to 18.5kW.

The motors are manufactured in an ISO 9001 environment and conform to the American and Canadian standards CSA C22.2 no. 100-95 and UL 1004.
