DESCRIPTION OF THE TPS-COMPACT
The TPS-compact pumping system consists of a
pump with an integrated controller and a forepump
and is available in sixteen models which differ in
the TPM size, high vacuum flange and voltage.
The models are:

Turbopump Description
The turbopump consists of a high frequency motor
driving a turbine fitted with many bladed stages
and Macrotorr stages. The turbine rotates in an
anticlockwise direction when viewed from the high
vacuum flange end.
The turbine is made of high-strength, light alumin-
ium alloy, and is machined from a single block of
aluminium. The turbine blades have five different
angles, from 44° to 12°, while the Macrotorr stages
are in the form of discs.
The turbine rotor is supported by permanently lu-
bricated high precision ceramic ball bearings in-
stalled on the forevacuum side of the pump.
The static blades of the stator are fabricated in
stainless steel. These are supported and accu-
rately positioned by spacer rings.
The Macrotorr stators are in the form of self-
positioning machined discs with pumping channels
and an opening restricted by the corresponding

rotor discs. These are fabricated in aluminium al-
loy.
During normal operation, the motor functions with
a power feed at 54 Vac three-phase at 1330 Hz
(TV81M) or 963 Hz (TV301). To reduce losses
during start-up to a minimum, the frequency in-
creases according to a ramp with a higher initial
voltage/frequency ratio.
A thermistor sensor is mounted near the upper
bearing to prevent the pump from overheating.
The pump is balanced after assembly with a resid-
ual vibration amplitude less than 0.01 µm.
Controller Description
The integrated controller is a solid-state frequency
converter which is driven by a single chip micro-
computer and is composed of a PCB which in-
cludes a power supply with a 3-phase AC output,
analog and input/output section, microprocessor
and digital section. The controller recognizes the
mains presence and converts the single phase AC
mains supply into a 3-phase, medium frequency
output which is required to power the pump.
The controller can be operated by a remote host
computer via the serial connection.
