1.4 Precautions for safe operation of the STP pump
1.4.1 Usable gases
The STP-iXR1606 is non-corrosion resistant type. Therefore, it cannot use the following gases
including chlorine and fluorine system gases.
Gases including alkaline metals except Li gas.
Gases including Ga, Hg, In, or Sn.
HBr gas.
WARNING
To prevent an accident, confirm the characteristics of gases to be used, referring to the
Material Safety Data Sheet (MSDS) you obtain from the gas supplier, and, keep MSDS
and a safety advice of gas supplier.
WARNING
Warn of the danger of the gas with the warning label when the use gas is hazardous
chemical material.
WARNING
Secure safety by wearing personal protective equipment when using the gas which
might influence damage health. In addition, take appropriate measure for depending
upon the properties of the gas to be used.
CAUTION
NEVER use any gas that is not specified as usable in this Manual. The use of such gas may
corrode the STP pump and damage it.
CAUTION
Introduce a dry N2gas (purge gas) to protect the inside of the STP pump when using gases
including hydrogen. The use of these gases may result in product damage.
CAUTION
The STP-iXR1606 is non-corrosion resistant type. Therefore, the use of corrosive gases and active
gases (radical gases) may damage Advanced Composite Materials (ACM) used in the part of rotor.
Note that the costs for repair of the product will be at the customer's own charge.

1.7 Operation principle of the STP pump
Turbomolecular pump (abbreviated to "STP pump" throughout this manual) is used for high vacuum
pumping. It is principally used for manufacture and inspection equipment of semiconductor, flat panel,
solar battery.
The STP pump (Figure 6) is configured so that rotor blade (1) and stator blade (2) are aligned
alternately in the axial direction. Gas molecules are pumped from the inlet port to the outlet port by
the high speed rotation of the rotor.
The STP-iXR1606 pump is a magnetically-levitated turbomolecular pumps, each with the following
features:
1. Oil free
2. Low vibration
3. High reliability
4. Compact size (Integrated control unit)
5. Dust and water protection
1. Rotor blade 4. Radial electromagnet 7. Touch down bearing
2. Stator blade 5. Axial sensor 8. Control unit
3. Radial sensor 6. Axial electromagnet

INTRODUCTION

1. Oil free
Rotor blade (1) is supported by the magnetic bearing without mechanical contact. Therefore, the STP
pump requires no lubrication oil unlike conventional turbomolecular pumps using ball bearings.
2. Low vibration
The magnetic bearing consists of 5 pairs of active magnetic bearings. The rotor is supported in the
radial direction by 4 pairs of radial direction active magnetic bearings that consist of radial sensor (3)
and radial electromagnet (4). A pair of axial direction active magnetic bearings consists of axial
sensor (5) and axial electromagnet (6) to support the rotor in the axial direction. Because the rotor is
supported without mechanical contact, it can rotate at low vibration.
3. High reliability
There is no periodic replacement of magnetic bearings unlike conventional turbomolecular pumps
using ball bearings because there is no friction. Taking into consideration a breakage of magnetic
bearings, touch down bearings (7) have been installed. They do not contact with the rotor during the
rated operation. The status of the rotor and magnetic bearing is continuously monitored via circuits
detecting rotor displacement, rotational speed and pump temperature. If an abnormality/error occurs,
the rotor will stop.
4. Compact size (Integrated control unit)
To save space for installation, the STP pump mounts the control unit (8) that includes the power
supply which converts the alternating input to direct current output. In addition, the following circuits
are integrated; the magnetic bearing control circuit, the motor drive circuit which drives rotor blade,
the supervisor circuit which monitors pump operation status and operates the pump in remote
operation mode.
5. Dust and water protection
The STP pump can be installed in the location subject to dust or sprays of water.

1.8 STP pump specification
External appearance, installation and unpacking method differ depending to the STP pump
specification. Refer to the followings:
Standard type
(Without anticorrosion
treatment type)
STP-iXR1606
The display unit iDT-001 is available as an optional accessory with the STP-iXR1606.
The display unit operates the STP pump, confirms the pump status and sets various settings. (refer
to Section 6.2 and the Instruction Manual of the "Display Unit iDT-001".)
