Variable Speed Drive - VSD / VFD Drives
Sales@VariableSpeedDrive.co.za. Variable speed drive fed motor from 50Hz to 60Hz. Most variable speed drive manufacturers require a reference to the neutral point of the winding, particularly for larger equipment. This connection serves as their primary "check" for unbalance in phase-phase and phase-ground circuits. As a side benefit, it keeps the VSD from accidentally damaging the machine winding insulation by over-voltaging the terminals by keeping the VSD and motor neutral at the same value. Variable ...
