1. What Is a Variable Frequency Drive 15kW?
A variable frequency drive 15kW is a power electronics device that adjusts the frequency and voltage supplied to an AC motor, enabling precise speed control. SHUYI’s 15kW drive is designed for medium-power applications, such as 3-phase motors in pumps, fans, and conveyor systems, reducing energy waste and extending motor life.

2. How SHUYI’s 15kW Drive Works
SHUYI’s variable frequency drive 15kW operates through three stages to optimize motor performance:
- AC-to-DC Conversion:
Rectifies incoming AC power (200V–690V) into DC using high-efficiency IGBTs, creating a stable DC bus for the next stage. - DC-to-AC Inversion:
Converts DC power into adjustable-frequency AC output (0–400Hz), allowing motor speed to match load requirements. SHUYI’s advanced vector control algorithm ensures smooth torque delivery even at low speeds. - Intelligent Control System:
Monitors real-time data like current, voltage, and temperature. Adjusts output parameters to prevent overloads and ensure consistent performance.
3. Core Advantages of SHUYI’s Drive
SHUYI’s 15kW variable frequency drive stands out for its technical excellence and industrial reliability:
- Energy Efficiency:
Achieves up to 30% energy savings by matching motor speed to actual load needs, ideal for applications like pumps that operate at partial capacity. - Precision Speed Regulation:
Offers speed control accuracy within ±0.1% of rated speed, critical for processes requiring consistent performance, such as textile machinery or CNC machines. - Rugged Design:
Features an IP54-rated enclosure that resists dust and splashes, along with built-in surge protection to withstand voltage fluctuations in unstable grids.
4. Key Applications
SHUYI’s variable frequency drive 15kW optimizes performance in various industrial sectors:
- Manufacturing Plants:
Controls conveyor belts to adjust material flow rates, reducing product jams and energy consumption. Ideal for medium-power motors in assembly lines. - Water and Wastewater Systems:
Adjusts pump speeds to match demand, preventing water hammer and reducing wear on pipes and valves. - HVAC Systems:
Enables energy-efficient operation of fans and chillers by matching motor speed to real-time cooling needs, cutting electricity costs in commercial buildings.
5. How to Choose the Right Variable Frequency Drive
When selecting a variable frequency drive 15kW, consider these factors:
- Motor Compatibility:
Ensure the drive’s voltage (e.g., 400V three-phase) and current rating (30A–50A for 15kW motors) match your motor’s specifications. - Control Modes:
Opt for drives with flexible modes like V/F control (for basic speed regulation) or vector control (for precise torque control). SHUYI’s drive supports both for maximum adaptability. - Certifications and Support:
Look for international standards like CE, UL, or ISO 9001. SHUYI provides a 5-year warranty and 24/7 technical support for global customers.
