Servomotors gain UL approval
Lenze's synchronous and asynchronous servomotors now fulfil the stringent fire and personal safety conditions required for export to the USA.
Lenze's synchronous and asynchronous servomotors now fulfil the stringent fire and personal safety conditions required for export to the USA The Hamelin-based drive technology manufacturer is looking to expand its business further in the USA and has therefore adapted its servomotors to obtain UL (Underwriter Laboratories) certification

Inverters: payback in 12 months in HVAC?
No matter what area of plant control you choose to scrutinise, there are few optional equipment alternatives that offer the operational benefits and cost savings of frequency inverters.
With these motors now certified, Lenze can offer a complete drive system for implementation in North America.
Even the new high-performance synchronous servomotors from the MCS range will be UL-certified from January 2004 and will also comply with CSA (Canadian Standards Association) requirements.
The 9300 servo controllers and 8200 vector frequency inverters are already UL-compliant, as are the cables, leads and mains chokes.
Before certification could be obtained, the motors first needed a few design modifications.
For instance, housing components such as plastic terminal box cable screws were replaced with metal components or the insulation material was changed.
In addition to UL-compliant design and choice of materials, certification also involves regular production inspections.
Motor and frequency inverter production is inspected every three months by a representative of the German Association of Electrical Engineers (VDE).
By using complete drive axes bearing the UL mark, it is much easier for mechanical engineering companies to export their equipment to the USA.
Compliance with fire and personal safety regulations is mandatory in the USA for operating production equipment. Request a free brochure from Lenze ...
