Ac motors cope better in harsh environments

Paul Boughton

Rotor (UK) is launching the new, high-specification Rotor NL range of 'standard' AC motors for use in demanding processing and pharmaceutical applications. The new Rotor range is designed and manufactured in Europe to a very high specification, making it suitable for applications that are too tough for conventional 'standard' models to reach their full operating life.

The highly robust design includes cast iron construction (from frame sizes 100 upwards), high-integrity seals and oversized bearings; these features ensure greater reliability and improved motor life in harsh working environments. Rotor believes there is a large part of the motor market that requires a better quality motor at a highly competitive price.

Commenting upon the launch of the Rotor NL range, Jerry Hodek, managing director of Rotor (UK), says: "At Rotor we want to ensure that our standard range of motors is the best available, allowing our 'standard' Rotor NL motors to be used with confidence in harsh operating environments. As a manufacturer we are also able to deliver modifications at very short notice, making our motors suitable for most applications. Our motors are also accredited to all major quality standards, allowing them to be fitted with complete confidence to any processing application."

The Rotor NL range is available in frame sizes up to 315, and certain sizes come with larger bearings than standard motors. The motors are readily available in face-, flange- and foot-mounted options from a large stock held by Rotor.

Rotor UK can also meet special demands at short notice. These can include special shafts and customised motors to provide additional security from harsh conditions, including epoxy protective coatings, ATEX certification, and increased ingress protection to IP56.
