De EM-A serie omvat nieuw ontwikkelde permanente magneetmotoren die gebruikmaken van de gepatenteerde salient-poolkern.
De rotor bestaat uit de salient-poolkern en een aan het oppervlak gemonteerde permanent magneet, waardoor de motorinductantie verandert afhankelijk van de rotatiepositie.
Noise filter for compliance with EMC directives.
Output filter for du/dt reduction and sinusoidal filter for sine wave output voltage.
Passive harmonic filter to reduce mains pollution.
The internal options comprise input and output extensions as well as communications options supporting the operation of the inverter within a network or connected to a personal computer or PLC.
In addition to the parameter unit that enables interactive operation of the frequency inverter the available external options also include additional adapters, modules and intercompatibility attachments.
The mains supply chokes compensate voltage fluctuations and simultaneously increase the efficiency. Applying the appropriate power choke an overall efficiency of up to 90% can be achieved.
The use of a power choke is especially recommended for main circuits where high capacities are switched, for example via thyristors.
