| Abstract |
Pulse Width Modulation (PWM) drives have the ability to cause EMI. The impact of Modern Adjustable Speed Drive (ASD) on wireless communications is investigated. Electromagnetic (EM) field in ASD environments was measured. The measurements were focused on frequencies used for radioservices where radiated emission may produce problems (ie. AM broadcasting). The measuring results show that modern Adjustable Speed Drives may disturb wireless communications that operate at LF and MF frequencies (up to couple MHz). They may also cause health hazards to humans if the maintenance works are carried out during the ASD operation while the cabinet door is open. |
