Vector Control 50hp 3 Phase VFD Ball Mill Variable Frequency Drive Custom

DLT-QG Series Vector control Ball Mill Dedicated Drive Variable Frequency Drive

Vector control type ball mill dedicated frequency converter is a high-performance frequency converter designed for the load characteristics of ball mills. It adopts vector control technology and achieves efficient and stable operation by accurately controlling the motor flux and torque.

FEATURES

• Vector control technology
  Equivalent three-phase AC power to two-phase DC power through coordinate transformation, achieving independent control of motor flux and torque, with fast dynamic response and high speed regulation accuracy, especially suitable for low-speed heavy load conditions.
• High torque output
  At low speeds (such as below 10Hz), it can still maintain a rated torque output of 150% -180%, meeting the requirements for full ball mill start-up and heavy-duty operation.
• Optimize starting performance
  Adopting a special starting mode (such as S-curve acceleration and deceleration) to shorten the start stop time (up to 10 seconds) and reduce the impact on machinery and the power grid.
• Multi speed operation
  Supports multi-stage speed settings (such as 3-32 stages), allowing for flexible adjustment of ball mill speed according to process requirements and optimization of grinding efficiency.
• Intelligent protection function
  Integrate overload, overcurrent, overvoltage, undervoltage, overheating and other protections to extend equipment life and reduce failure rates

Application advantages

• Energy Saving
  By optimizing motor operation through vector control, the energy saving rate can reach 13.5% -20% (such as comprehensive energy saving after removing hydraulic couplings), reducing production costs.
• Improve grinding efficiency
  Accurately control the speed of the ball mill to avoid excessive grinding, shorten the grinding cycle, and improve product quality.
• Extend equipment lifespan
  Smooth start stop and stable operation reduce mechanical wear and maintenance costs.

Selection Suggestions

• Power matching
  Choose a frequency converter based on the power of the ball mill motor, and recommend models with the same or slightly higher power (such as a 250kW frequency converter for a 250kW motor).
• Control mode
  Prioritize vector control (SVC) or closed-loop vector control (VC) to ensure low-speed and high torque output.
• Functional requirement
  Attention should be paid to whether it supports multi speed, PID regulation, communication interfaces (such as Modbus, Profinet), and other functions.
