40HP Single Phase to 3 Phase VFD

With easy parameter configuration and rugged construction, CSIVEI factory’s 40HP Single Phase to 3 Phase VFD provides a solid foundation for basic motor speed control applications.

Core Parameters and Specifications

Typical Applications

The CSIVEI 40HP Single Phase to 3 Phase VFD is engineered for heavy-duty industrial applications requiring high starting torque and continuous duty:

Large pumps – irrigation pumps, drainage pumps, main water supply pumps

Centrifugal compressors – industrial air compressors, refrigeration systems

HVAC chillers – screw chillers, centrifugal chillers, large air handlers

Mining equipment – slurry pumps, ventilation fans, crushers

Metalworking machinery – lathes, milling machines, presses

With advanced vector control and multiple communication options, it integrates seamlessly into automated production lines.

Advanced Control Technology

The CSIVEI 40HP Single Phase to 3 Phase VFD employs state-of-the-art motor control algorithms to deliver precise speed regulation and exceptional torque performance across the full speed range.

Sensorless Vector Control (SVC) – Provides high starting torque (up to 150% at 0.5Hz) without the need for an encoder, making it ideal for applications requiring stable low-speed operation such as conveyors, mixers, and hoists.

V/F Control – A classic control mode suitable for fans, pumps, and general-purpose applications where simplicity and reliability are prioritized. Auto-tuning function automatically identifies motor parameters for optimal performance.

Closed-Loop Vector Control (CLVC) – Available on select models, this mode uses an encoder feedback to achieve 0.1% speed accuracy and 200% starting torque, meeting the demands of high-precision applications like CNC spindles, extruders, and cranes.

Customer Case

Customer Case: Constant Pressure Water Supply

A residential complex in Southeast Asia was experiencing fluctuating water pressure during peak usage hours, leading to tenant complaints. The existing pump system ran at fixed speed, wasting energy during low-demand periods.

Solution: A CSIVEI 3-5.5kW VFD was installed to control the main booster pump, with a pressure sensor providing feedback to the built-in PID controller.

Results:

Stable water pressure maintained at 4.5 bar regardless of demand

Energy consumption reduced by 38% compared to fixed-speed operation

Pump motor starts reduced from 20+ times per day to continuous smooth operation

Payback period achieved in 11 months

The system has been operating reliably for over two years with no unscheduled downtime.
