YUFU · MAGNETIC LEVITATION SERIES

MAGNETIC LEVITATION

No mechanical contact.
No conventional friction.

0
Mechanical Contact in the Bearing System

Active electromagnetic force supports the rotor without
conventional bearing contact, reducing friction and
eliminating the need for bearing lubrication.

01

Non-Contact Rotation

The active magnetic bearing keeps the high-speed rotor suspended
without conventional mechanical bearing contact.

02

Oil-Free Operation

No lubricating oil is required in the magnetic bearing system,
supporting clean air delivery and simplified maintenance.

03

Frequent Start / Stop

The magnetic suspension architecture supports repeated
start-stop operation without conventional bearing wear.

04

Safe Shutdown

Self-power generation maintains rotor levitation during
a power interruption until the system completes a safe stop.

CORE TECHNOLOGY

Five technologies.
One integrated blower.

The aerodynamic, motor, bearing, power-safety and variable-frequency
systems are designed together as a complete high-speed blower platform.

01
3D Flow Impeller
High-strength aluminum alloy centrifugal impeller manufactured
with precision CNC machining for efficiency, durability
and aerodynamic stability
.
02
High-Speed PMSM
High power density and reduced thermal loss support efficient
high-speed operation, with motor efficiency exceeding
95% according to the product specification.
03
Magnetic Bearing
Controllable electromagnetic force levitates the rotor,
reducing conventional contact, friction and lubrication.
04
Self-Power Generation
During a power interruption, the system uses stored rotational
energy to support rotor suspension until a controlled shutdown.
05
Dedicated High-Speed VFD
The dedicated VFD and cooling architecture adapt blower speed
to operating demand and support stepless airflow control.

EFFICIENCY ADVANTAGE

Lower energy use.
Lower operating cost.

OPERATING PRINCIPLE

Levitate.
Accelerate.
Move air.

The YF Series uses active magnetic bearings and a
high-speed permanent-magnet synchronous motor to directly
drive the aerodynamic impeller.

01

Rotor Levitation

The magnetic bearing control system generates electromagnetic
force to suspend the rotor without conventional bearing contact.

02

High-Speed Motor Drive

The permanent magnet motor accelerates the suspended rotor and
directly drives the centrifugal impeller.

03

Aerodynamic Compression

The three-dimensional impeller converts rotational energy
into kinetic energy and pressure for continuous air delivery.

04

Intelligent Adjustment

The dedicated VFD and PLC control system adjust operating
speed and airflow according to process demand.

OPERATING RANGE

The YFC Series covers multiple pressure levels and motor powers,
allowing model selection according to required airflow,
discharge pressure and operating conditions.
