Medium To High Power Servo VFD Variable Frequency AC Motor Inverter Drive

The medium to high power universal servo frequency drive is a high-end driving equipment developed by our company that combines servo control and frequency conversion technology. It is designed specifically for high load and high-precision industrial scenarios and has a wide range of applications in fields such as power, metallurgy, petrochemicals, mining machinery, and rail transit.

• High power density and wide speed range: Support kilowatt to megawatt level power output to meet the requirements of heavy-duty equipment. The speed ratio can reach 1:10000 or more, with a speed accuracy of ± 0.01%, suitable for complex working conditions. Typical case: Metallurgical rolling mill achieves stepless speed regulation from 0-3000r/min through frequency converter, with speed fluctuation<0.5%.
• Strong overload capacity and dynamic response: 3 times overload capacity for 1 minute, 1.5 times overload for continuous operation, suitable for instantaneous impact loads. The acceleration and deceleration time is less than 50ms. If an elevator uses a frequency converter, it can achieve an acceleration of 2m/s ² to ensure smooth operation.
• Multi axis synchronization and interpolation control: Supports 4-16 axis synchronous control, with a positioning accuracy of ± 1 arc second, meeting the high-precision requirements of CNC machine tools, robots, and others. The electronic gear ratio function achieves precise matching of speed/position between different shafts with an error of less than 0.001mm.
• Energy efficiency optimization and energy feedback: Adopting vector control and direct torque control, the efficiency is ≥ 97%, saving 20% -40% energy compared to traditional equipment. The energy feedback unit can feedback braking energy to the power grid with a feedback efficiency of>90%.
