17 Technical Information
Turbopump Description
During normal operation, the motor functions with a power feed at
54 Vac three-phase at 1167 Hz. To reduce losses during start-up to a
minimum, the frequency increases 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 residual vibration
amplitude less than 0.01 m.
