Low Voltage VFD Frequency Inverter

PUTAI Low Voltage VFD Frequency Inverters provide adjustable-speed control for industrial AC motors. They serve OEMs, equipment manufacturers, distributors and maintenance teams sourcing drives for new equipment, system integration or replacement projects.

Sensorless Vector Control: Supports low-speed stability and improved low-frequency torque performance.

Speed and Torque Control: Supports speed and torque adjustment for applications with changing load demands.

Motor Control Optimization: Dead-zone compensation improves low-frequency torque performance and helps suppress motor oscillation. Optimized PWM control supports motor control performance.

EMC-Oriented Design: Incorporates electromagnetic compatibility considerations for industrial system integration.

Protection and Overload Capability: Hardware design supports reliable operation, with protection functions and overload limits depending on the model.

Modular Design and Protective Coating: Features modular hardware circuitry and a three-proof coating process.

Motor Parameter Identification: Supports drive-system stability and control accuracy.

Integrated Automation: Built-in PLC and PID control, automatic sleep/wake-up and up to 16 speed settings.

Flexible Control Interfaces: Multiple input/output terminals and main and auxiliary speed-reference methods support different control arrangements.

Environmental Adaptability: Designed with consideration for grid conditions, temperature, humidity and dust. Permitted operating limits depend on the model.

Water Supply and Booster Pumps: Adjust pump speed to changing water demand. PID control and automatic sleep/wake-up can support pressure regulation when configured for the application.

HVAC and Industrial Ventilation: Regulate fan and blower speed to match airflow requirements in ventilation, air-handling and exhaust systems.

Belt Conveyors and Material Handling: Adjust conveyor speed to coordinate material movement across production, sorting and packaging lines.

Industrial Process Machinery: Provide variable-speed control for compatible mixing, feeding and processing equipment requiring adjustable operating speeds.

Factory Automation: Support compatible AC motor-driven machinery using functions such as PLC control, multi-speed settings and external speed references.

PUTAI supports OEMs, equipment manufacturers, distributors and maintenance suppliers sourcing drives and related industrial electrical products.

OEM Supply
For new equipment projects, buyers can provide motor nameplate details, application requirements, power supply information and required control functions. PLC/PID control, multi-speed operation, external speed references and system interfaces can be assessed against the proposed model. OEM labeling, packaging and other project requirements can be discussed according to the available supply arrangements.

Replacement Matching
For replacement projects, provide the existing inverter model, motor nameplate, input supply details and available wiring or installation photos. Matching should consider input voltage, motor current, control mode, load characteristics, speed range, braking requirements, interfaces and installation conditions-not rated power alone.

Distributor Supply

Distributors and spare-parts suppliers can submit model requirements, quantities, end-user applications and known technical specifications to support product enquiries and recurring orders.

Related Product Sourcing
PUTAI's portfolio includes AC motors, DC motors, medium-voltage motors, starters and drives, motor windings and related components. Availability and compatibility depend on the requested products and project requirements.

PUTAI Electric Motor Equipment Co., Ltd. specializes in the R&D, production and supply of electric motors and related electrical equipment. Its published company profile lists:
Factory area: 200,000 m²
Workforce: More than 120 employees
Technical team: 18 engineers
Fixed assets: RMB 80 million
Motor industry experience: More than 25 years
These figures describe the wider company, not VFD-specific production capacity.

PUTAI's published manufacturing information covers material preparation, manufacturing, intermediate inspection, testing, packing and shipment across its broader business. Its documented motor processes include winding, insulation treatment, rotor production, assembly and motor testing; these should not be interpreted as VFD production procedures.

For inverter projects, buyers can request applicable product specifications, operating manuals, wiring information, inspection records and conformity documents. Documentation availability and scope depend on the actual model and supply arrangement.
