Shenzhen INVT Electric Co., Ltd.
INVT began with variable-frequency drives in Shenzhen in 2002. Today, its industrial-automation business combines motor drives, servo systems, PLCs, operator interfaces and elevator controls. Its development history includes the Suzhou industrial park and Guangming headquarters, while its published laboratory accounts describe both manufacturing-process research and test-equipment development. For a GD350A project, the defining choices are the motor, control mode, expansion hardware and installed electrical system.

From a Shenzhen drive business to a wider automation supplier.
The motor-drive operation belongs to an identifiable listed company, with a broader industrial product business.
Origin and legal identity
INVT’s company history begins in 2002 with its first generation of VFDs and records the introduction of vector drives in 2005. It entered the Shenzhen stock market in 2010. The 2024 annual report identifies the Chinese legal entity as 深圳市英威腾电气股份有限公司, stock code 002334, and gives its office at the INVT Guangming technology building in Shenzhen. These records connect the English brand to the reporting enterprise.[1][5]
Industrial automation is the relevant business here
The annual report lists PLCs, controllers, servo systems, frequency drives, HMIs, motors, sensors, elevator controls and industrial IoT within industrial automation. INVT’s corporate introduction separately describes network power, electric-vehicle equipment and photovoltaic/storage products. For machine builders, the useful breadth is the ability to discuss motor control together with sequence control, positioning and the operator interface; the enquiry should name those industrial components.[1][5]
Suzhou and Guangming in the published development record.
The company timeline dates the operating-site milestones rather than treating every group address as a drive factory.
- 2014
Suzhou Phase I enters operation
INVT records the first phase of the Suzhou industrial park becoming operational.[1]
- 2018
Guangming headquarters enters operation
The timeline identifies the Guangming headquarters milestone in Shenzhen.[1]
- 2023
Suzhou Phase II opens
The same account records Phase II opening and the start of Zhongshan industrial-park construction.[1]
Production development and headquarters have different roles
This chronology gives a concrete picture of INVT’s expansion: an operating industrial park in Suzhou, a headquarters in Guangming, and a later second Suzhou phase. The statutory report confirms the Guangming office location. For a delivered drive or cabinet, the order documents should identify its assembly location and responsible supplying entity; those details belong to the specific supply rather than the headquarters label.[1][5]
GD350A selection starts with the motor and the fitted interface.
The current official product page distinguishes control capability from expansion hardware.
Motor technology and control mode
GD350A supports asynchronous and permanent-magnet synchronous motors through V/F, open-loop vector and closed-loop vector control routes. Synchronous-reluctance operation is associated with customized software on the current product page. For a pump or production machine, state the actual motor technology, feedback and operating cycle together; those choices determine the configuration being discussed, including the software needed for a SynRM installation.[2]
Communication cards are part of the equipment list
INVT lists optional communication cards for PROFINET, CANopen, PROFIBUS-DP, EtherNet/IP, Modbus TCP and EtherCAT. It also identifies optional I/O and external-24 V power cards. A PLC-connected GD350A offer should therefore name the installed card and the required signal functions. The official download area separately names GD350A, GD350A-S and GD350A-HR documents; retaining the full variant prevents the wrong hardware instructions from entering the commissioning package.[2]
Temperature feedback and software handling are part of the machine interface.
These GD350A functions affect the motor wiring and the handover to the maintenance team.
The motor’s temperature signal
The product page identifies direct AI/AO connections for PT100, PT1000, KTY84 and PTC sensors. This makes the motor’s fitted sensor a useful item in the enquiry. Put the agreed sensor connection and protection response in the wiring and commissioning scope, especially when the drive replaces a unit whose temperature-monitoring arrangement is already part of the machine.[2]
Programmable expansion and firmware
A separately described programmable expansion card supports instruction language, ladder diagram and sequential function chart, with 16K-step storage. Firmware-maintenance routes include RS485, local serial connection, 4G expansion and USB storage. VFDMatch’s handover advice is to request the installed hardware list, software version, parameter backup and any expansion program with the delivered equipment, so the maintenance team receives the configuration actually used.[2]
Process research and test-equipment development are separate laboratory functions.
Two accounts published on 9 April 2020 describe the work behind manufacturing processes and automated testing.
Materials, assembly and failure analysis
INVT assigns its process automation laboratory work on auxiliary materials, production methods, tools and manufacturability standards. The account also describes investigating failures found during production or reported from the market, proposing improvements and verifying key-component assembly and production processes. This is a useful description of how manufacturing problems are examined and fed back into process development, rather than simply a general claim about product quality.[3]
Measurement and automated test systems
The equipment development laboratory account focuses on measurement and test solutions for individual business units. It describes a progression from manual testing to semi-automatic and fully automatic systems, including parallel testing and remote monitoring in the latter generation. The two laboratories are not consecutive assembly steps. Their published responsibilities concern process improvement and test-system engineering; the dated accounts do not establish the inspection result of a particular delivered drive.[4]
An Indonesian pulp pump brings motor control and a long cable into the same project.
INVT’s 23 December 2025 application report provides a specific GD350A/SynRM engineering example.
Starting behaviour, speed control and cable distance
The customer requirements in the report include starting torque, speed regulation, reliable operation and a 250-metre distance between the motor and drive. INVT proposes GD350A with a synchronous-reluctance motor. This gives the selection a concrete process setting: a pulp-production pump, the motor-control algorithm and the electrical installation all form part of the requested upgrade.[6]
Keep the cabinet description explicit
The same report separately names a GD800 PRO cabinet and DC, input and output reactors in its installation description. Preserve those equipment names when discussing the example; the listed reactors are part of the reported system proposal, not accessories automatically included with every GD350A. The report’s energy-saving language is qualitative here, with no independently measured percentage reproduced.[6]
What a comparable enquiry needs
For a similar pulp-pump project, provide the motor technology and nameplate, pump operating range, starting requirement, cable length and existing electrical arrangement. Ask INVT to identify the selected drive, software, cabinet and reactors together with the commissioning scope. These are VFDMatch’s project-preparation notes drawn from the particular constraints in this report.

Buyer questions
Can GD350A control a synchronous-reluctance motor?
The current product page lists SynRM control with customized software. Name the motor and software configuration in the offer.
Are the listed fieldbus connections supplied together?
The product page describes optional communication expansion cards. The fitted card belongs in the equipment list.
Why does the pulp-pump case also name a GD800 PRO cabinet?
The manufacturer’s report names GD350A/SynRM in its drive proposal and separately identifies that cabinet and reactors. A comparable quotation should explicitly identify all supplied equipment.
Which documents should accompany a GD350A replacement?
Request the manual for the exact variant, fitted-card information, wiring, software version and the parameter or expansion-program backup used during commissioning.
