GK820 VFD Applied in Magnetic Levitation Blowers

• Magnetic Levitation Bearing System
  The core technology lies in the magnetic levitation bearing system, which uses electromagnetic forces to suspend the rotor in mid-air, enabling contactless and frictionless rotation.
• Drive System
  High-speed permanent magnet synchronous motors (PMSMs) are typically employed as the drive system. These motors, powered by variable frequency drives (VFDs), generate an adjustable-frequency alternating current which creates a rotating magnetic field in the stator, driving the shaft at high speeds.
• Control System
  Advanced microprocessors and sensor technology allow real-time monitoring and control of the blower’s operating state, ensuring precision and reliability.
• Intelligent Monitoring
  Smart control systems collect and process operational data in real time while adjusting control strategies based on process requirements, enabling intelligent start-stop and variable-frequency speed regulation

Control Scheme for Magnetic Levitation Blowers

1. Magnetic Suspension Control
   The magnetic levitation controller activates the bearing system, suspending the motor’s rotor.
2. Operational Command Execution
   The HMI sends operational commands to a PLC. The PLC then relays these commands to the VFD/AC Drive, starting and regulating the motor operation.
