Where to buy a VFD for a motor without choosing the wrong supplier
The safest place to buy a chastotnik, meaning a variable frequency drive for an electric motor, is a specialist industrial automation supplier. A good supplier checks the motor nameplate, confirms 220 V or 380 V supply, verifies stock and does not sell a drive that is "almost the same". For Ukraine, the fast route is simple: open the variable frequency drive catalog, filter by power and brand, then send the motor nameplate photo to the manager. This prevents common mistakes, such as buying a 3x220 V output drive when the motor needs 3x380 V, or choosing a model without enough current reserve. In practice, a buyer looking for a drive needs three things: correct sizing, a real price and fast shipment, in that order.
In short, what to look at before buying. For a motor, the starting point is always voltage, rated current and load type, not the machine name. Price is best compared together with warranty, lead time and what is included: keypad, EMC filter, braking resistor. And a "near me" request in industrial automation almost always means a supplier with stock and technical support rather than the nearest storefront, which matters more than physical distance.
Which chastotnik supplier is right for buying
The right seller is not simply the one with the lowest advertised price. The right seller can confirm the drive model, input voltage, output voltage, current rating and shipment date. A VFD is not a light bulb. One wrong digit can mean the motor will not start, or the drive will trip during the first ramp-up.
| Where to buy | When it works | Main risk |
| Specialist automation store | Sizing for a motor, pump, fan, machine or conveyor | You need to provide motor data; otherwise sizing is approximate |
| Official brand dealer | When you need a specific Schneider, Danfoss, Delta, Veichi or INVT series | A cheaper or faster alternative may not be offered |
| Marketplace | When the exact model is already known and startup support is not needed | Warranty and technical support can be unclear |
| Used drive seller | Temporary replacement when budget is very tight | Unknown operating history, aged capacitors and no clear service path |
For most buyers, the safer start is a specialist catalog. On chastotnik.ua we use separate pages for frequency converters, VFDs for electric motors and VFDs for pumps. If you are already comparing models, open the VFD rating article. It helps explain why a budget AC10, a general-purpose GD20 and a higher-priced Altivar are bought for different jobs.
What to send a seller when you need a chastotnik for a motor
For a motor, the seller needs nameplate data, not just the machine name. That is the difference between proper sizing and guessing. If the nameplate photo is blurred, write the values manually: kW, A, V, Hz, rpm and star/delta connection data.
Find motor power in kW and rated current in amperes.
Check the site supply: single-phase 220 V or three-phase 380 V.
Read the motor voltage line: 220/380 V or 380/660 V. This is where many errors start.
Describe the load: pump, fan, conveyor, compressor, spindle or mixer.
Mention whether you need PID control, external keypad, Modbus, braking or generator operation.
Example. A 2.2 kW pump on single-phase supply does not always need the same drive as a 2.2 kW fan. The pump may need PID and a 4-20 mA pressure sensor. The fan usually needs smooth acceleration and quiet operation. A compressor is stricter: starting torque, inertia and overload trips matter. If you are choosing between a soft starter and a VFD, read the soft starter vs VFD comparison first.
Where to compare prices and get a good deal
A good deal on a chastotnik is a fair price for the correct model, with real stock or an honest lead time. A cheap drive without the required current rating quickly becomes expensive: line downtime, repeat shipping and a second sizing process. Compare in two steps: technical fit first, price second.
Compare input: 1x220 V, 3x380 V or another site supply.
Compare output: some 220 V input models output 3x220 V, not 3x380 V.
Compare current: use the motor nameplate amperes, not only kW.
Compare features: PID, vector control, braking transistor (built in on some models; on higher-power series the braking chopper can be external), EMC, Modbus RTU.
Compare service: who will help with P0/P1 parameters (the parameter group prefix depends on the brand: Veichi uses F-groups, INVT and Delta-style drives use P-groups), terminal wiring and the first fault code.
There is one practical pitfall that trips buyers most often. If the drive outputs 3x220 V, the motor must also be rated for 3x220 V, or connected in delta for 220 V. Otherwise a motor wired for 3x380 V in star will be under-supplied and will not reach rated torque. So verify not only the drive input, but also the voltage the motor windings are actually connected for.
What makes up the price of a VFD: first power and rated current, then brand and series (a budget Veichi versus Schneider or Danfoss), and finally options such as a braking resistor, EMC filter, remote keypad or expansion board. For a quick budget check, use our article on VFD price in Ukraine. The final price should still be checked in the product card or with a manager, because stock and currency can change. The chastotnik.ua VFD catalog includes many active series: Veichi AC10/AC310, INVT GD20/GD200A, Delta MS300/VFD-EL, Schneider Altivar, Danfoss VLT, Mitsubishi FR-D/FR-E and others. That makes comparison easier because you do not need to jump across ten different websites.
How to read the query "chastotnik suppliers near me"
If you are in Ukraine, "near me" for a VFD often means a supplier that ships fast and answers wiring questions, not only the nearest storefront. In practice it looks like this: for Kyiv, pickup from the warehouse; for Lviv, Dnipro, Odesa, Kharkiv or a smaller town, shipment by Nova Poshta on the payment day when in stock, with proper packaging and pre-start support. So before ordering, it is worth asking the manager two things up front: whether the specific model is in stock and the rough quote turnaround time. That saves more than physical distance to a shop.
| Buyer query | Real need | Where to look |
| Where can I buy a chastotnik? | A VFD catalog with prices and real stock | /preobrasovateli |
| Chastotnik for a motor | Sizing by motor nameplate | /invertors-for-motors |
| Compare chastotnik prices | Series and budget comparison | VFD price article |
| Good deal on a chastotnik | Balance of price, warranty, features and lead time | VFD rating |
We do not recommend buying a VFD only because the listing says "fits 2.2 kW". For a pump, a fan and a lifting mechanism, that phrase can mean different things. It is better to spend 5 minutes checking the nameplate than to diagnose an OC or OL trip on site later.
Frequently Asked Questions
Where can I buy a chastotnik?
In Ukraine, you can buy a chastotnik from a specialist industrial automation store, for example in the VFD catalog on chastotnik.ua. Before paying, prepare a clear motor nameplate photo and check stock with the manager.
Who sells chastotniks for motors?
Automation stores, brand dealers and some electrical suppliers sell them. For a motor, choose a seller who checks current, voltage and load type, not only one who ships a box.
Where can I compare chastotnik prices?
Start with the catalog, then use the VFD price article to understand the range. Compare models with the same voltage class and similar current rating, otherwise the numbers are misleading.
Can I buy a chastotnik online without consultation?
Yes, if you already know the exact model, voltage and current. For a first motor sizing, ask a manager and send the nameplate photo.
What matters more: price or brand?
Technical fit comes first, then price and brand. A simple fan can use a budget series, while a machine tool or a PID pump should not be selected only by the lowest price.
The practical next step is simple: open the chastotnik catalog, choose supply voltage and power, then verify the model against the motor. If you need a drive for a specific motor, start from VFDs for electric motors. That way you do not just find companies that sell chastotniks; you buy a drive that should start correctly on your site.
