Matching Inverter Guidance
A VFD is selected around the three-phase motor and application duty—not from frame size alone.
Electrical match
Confirm motor nameplate voltage, full-load current, frequency, overload duty and the required control method.
Low-speed operation
Review cooling and thermal margin for prolonged low-speed duty; forced ventilation or an inverter-duty motor may be required.
Installation protection
Long motor cables may require output reactors or dV/dt filters, with EMC filters and braking resistors selected where applicable.
Important: A normal capacitor-start/capacitor-run single-phase motor should not be assumed suitable for operation from a standard three-phase VFD.
