Three phase motor choke. Connected in the inverter output circuit between the inverter and the motor. This will help to reduce reflected waves, often caused by long or multiple motor cables. Reflected waves can damage the inverter output devices and cause greater RFI (radio frequency interference), this may cause any RFI filter fitted to be damaged. Motor chokes are recommended for all inverter application, regardless of motor cable length, for motor cable lengths of 30m or more motor chokes should be very seriously considered.
