ZF900-E medium to high power servo variable frequency 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.
Key Features
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%.
Application
Heavy industry sector
Mine hoist: The frequency converter drives the hoist motor, achieving ± 0.1m/s speed control and overload protection response time<10ms.
Oil drilling rig: By controlling the speed of the mud pump through a frequency converter, the pressure fluctuation is less than 2%, which extends the service life of the equipment.
High-end equipment manufacturing
Numerical Control Machine Tool: The spindle frequency converter achieves stepless speed regulation from 0-24000r/min, with a machining accuracy of ± 0.005mm.
Industrial robot: Six axis servo frequency converter achieves ± 0.01mm repeatability positioning accuracy and trajectory tracking error<0.1 °.
New Energy and Infrastructure
Wind power generation: The doubly fed frequency converter achieves maximum power point tracking (MPPT), increasing power generation efficiency by 5% -8%.
Rail transit: The output torque fluctuation of the traction frequency converter is less than 2%, meeting the acceleration requirements of the subway from 0-80km/h.
