Jiangsu GTAKE Electric Co., Ltd.
Founded in Nantong in September 2009, GTAKE combines industrial drives with vehicle controllers and electrical-test equipment. Its production presentation identifies incoming, board and assembled-product checks. For film converters, the GK820T application explains how encoder feedback, changing roll diameter and tension compensation fit into a slitting line.

The company behind the brand
The official English site identifies Jiangsu GTAKE Electric Co., Ltd. Its corporate history starts with both industrial AC drives and vehicle motor controllers, explaining why today's catalogue spans production machinery and power-conversion systems. A Nantong municipal 2021 project entry independently names 江苏吉泰科电气股份有限公司 for passenger-vehicle controller research. That record concerns a research project, rather than a certification of all industrial drives.[1][6]
Shenzhen and Nanjing have distinct research roles in the published company geography.
The origin in Nantong and the named research bases can coexist without treating every contact as a factory.
Two named research bases
The R&D presentation separately identifies the Shenzhen R&D Center and Nanjing R&D Center. The company describes work across motor control, industrial drives and clean-energy power conversion. For a technical enquiry, the important connection is the team responsible for the offered drive or system, its software configuration and the destination support arrangement.[5]
Industrial control and test systems
The corporate development path associates PowerPard equipment and four-quadrant drive systems with automotive, aircraft and general-equipment test rigs. Those systems have a different supply scope from a film-slitter motor drive. Keeping the production-machine and electrical-test discussions separate makes the catalogue easier to use without treating unlike equipment as substitutes.[1]
The factory's published workflow puts checks before and after assembly.
The quality graphic shows ten connected activities from purchasing through shipment.
Purchasing and incoming checks
The graphic begins with purchasing, incoming inspection, and preparing/issuing materials. It then places a single-board processing test before assembly. This sequence distinguishes component receipt and board-level verification from checks on a finished unit; they are separate activities in GTAKE's published manufacturing flow.[2]
Assembly and product testing
After assembly, the graphic identifies process inspection and a further test stage. It does not name a test load, duration or acceptance threshold, so those details should come from the proposed equipment's production documentation. The useful factory question is which recorded checks apply to the serial-numbered drive being supplied.[2]
Packaging through shipment
The final sequence is packaging, warehouse and shipment. For an export order, VFDMatch recommends connecting that handover to the actual accessory list, model identity and technical documents. These are practical order details a buyer can discuss against the manufacturer's published flow.[2]
GK820T's winding task sits at the end of a moving-web process.
The manufacturer's application follows the film through nip rollers, alignment and slitting before the final roll.
Locate the driven mechanism
In GTAKE's application explanation, film leaves the upstream roll mechanism, passes through the nip roll and deviation-correction system, and reaches the slitting mechanism. The cut material is then wound into finished rolls. The page identifies GK820T as the drive for the winding motor, giving the equipment a specific place in the machine rather than an unspecified automation role.[3]
Changing roll diameter
The described drive includes an encoder interface without a separate card. In the stated mode without a tension sensor, it calculates winding diameter and supports constant-tension control. The page also describes a user-defined taper-tension curve. These functions address a changing roll, so the useful application information includes the material, core and final diameters and the intended tension mode.[3]
Friction and inertia compensation belong to the winding mechanism.
The GK820T explanation goes beyond a frequency command by naming the mechanical compensation functions.
Compensation during motion
The application lists sliding-friction and high-speed friction compensation, together with a mechanical inertia compensation coefficient. Those functions are relevant when the winding roll accelerates, changes size and experiences different mechanical resistance. They give a machine builder concrete subjects to discuss with the drive supplier during application engineering.[3]
An enquiry tied to the web
For this application, VFDMatch recommends describing the web path, winding direction, motor and encoder, diameter range and acceleration cycle. Add whether tension comes from a measured sensor or the described sensorless calculation, and the required taper behaviour. This gives the supplier a defined mechanical task to evaluate instead of asking for a generic drive of a particular kW rating.

Buyer questions
Where did GTAKE originate?
Its official history records September 2009 in Nantong, Jiangsu. The research presentation separately names Shenzhen and Nanjing centres.
What does GK820T control in the film-slitter example?
The manufacturer identifies it as the winding-motor drive, with diameter calculation, encoder input, taper tension and compensation functions.
Does the H suffix in the manual's 30 kW example include a braking resistor?
It identifies a built-in brake chopper and DC reactor. The resistor remains external.
What checks appear in the published factory workflow?
Incoming inspection, single-board processing test, process inspection and a further product test appear before packaging, warehousing and shipment.
