75 kW VFD: what site we ship it for

75 kW units we ship for 75 kW 380 V motors with nominal current around 145-150 A. Typical customer this year: trunk and back-flush pumps at water utilities. Screw compressors 13-14 m³/min in cement and woodworking. Crushers and shredders at foundries and mining sites. Aspiration on big 2000+ t grain elevators. Traction drives on test rigs. Dry-mill grinders. On 55 kW these jobs no longer hold: a compressor with 380+ A inrush exceeds the limit, the drive trips on OC within 0.2 s.

From the grid: 3-phase 380 V, the 660 V option exists for mining (INVT GD350-075G-6). Rated draw 145 A, breaker 200 A C-curve, cable 70 mm² copper up to 30 m (recalc beyond for voltage drop). Veichi AC70-T3-075G/093P per datasheet holds 150% for 60 s (G mode, crushers) and 110% continuously (P mode, pumps). INVT GD350-075G-4 is high-class with closed-loop vector control via encoder (for crane or hoist), Modbus RTU + Profinet onboard.

Which model we ship in 8 out of 10 cases

From main stock: Veichi AC70-T3-075G/093P (mid-tier, our top product in this band, in stock monthly). INVT GD200A-075G/090P (European feature equivalent). INVT GD350-075G-4 when closed-loop vector with encoder is needed for crane/hoist. Schneider ATV930D75N4 when the customer asks for Europe and accepts 7-14 days. Delta VFD750C43A: ship to order from Taiwan warehouse. ABB ACS580-01-145A-4 we ship when the site is already on ABB. Veichi SI23-T3-075G-A (solarized, MPPT 200-820 V) we ship for 75 kW solar pump stations without batteries.

Before paying we ask. First: load type G or P? Crusher, compressor, shock-load conveyor (G); pump or fan (P). This decides 75 kW in G or 55 kW in P. Second: braking resistor. For a 75 kW centrifuge the BR draws 18-22 kW. Third: cable length. Over 30 m a du/dt filter is required; over 100 m a sine filter. Fourth: ambient IP. Base drive is IP20; for dusty production we ship in a separate IP54 cabinet. 2-year warranty, 1-3 day delivery from our Kyiv warehouse.

Frequently Asked Questions

Which motor is a 75 kW VFD selected for?

A 75 kW VFD is selected for a three-phase electric motor with a rated power of 75 kW when the motor current does not exceed the drive rated current. Before ordering, check the motor nameplate: power, voltage, current, and wiring diagram.

What input voltage is required for a 75 kW VFD?

The input voltage depends on the site supply and the motor. For a single-phase 220 V supply, choose a 220 V input model if it is available for this power. Industrial motors usually require a 3-phase 380 V VFD.

Do I need extra power reserve for a 75 kW VFD?

For pumps and fans, selecting by the motor rated power and current is often enough. For heavy starts, conveyors, compressors, mixers, or frequent acceleration cycles, allow extra current reserve or move to the next power size.

Where are 75 kW VFDs used?

75 kW VFDs are used to control the speed of pumps, fans, conveyors, machines, and other equipment with asynchronous motors. The exact application depends on load torque, duty cycle, and installation conditions.

How can I quickly choose the right model?

Send a motor nameplate photo or provide the power, voltage, rated current, number of phases, and load type. A Chastotnik.ua manager will select a compatible VFD, check availability, and advise on basic startup parameters.
