Claim 3:
4. The turbo compressor according to claim 1,
wherein the drive support unit includes first and second coils through which respective first and second coil currents in the predetermined current range flow, and
wherein
the driving magnetic flux BM is generated in the drive support unit as a result of the flow of the first coil current through the first coil, the supporting magnetic flux BS is generated in the drive support unit as a result of the flow of the second coil current through the second coil,
a value of the first coil current flowing through the first coil when the driving torque corresponding to the maximum torque load is generated is represented by a maximum torque current IBMmax,
a value of the second coil current flowing through the second coil when the maximum radial load of the drive shaft is supported is represented by a maximum support force current IBSmax, and
a combined magnetic flux generated in the drive support unit by causing a current obtained by adding together the maximum torque current IBMmax and the maximum support force current IBSmax to flow through the first and second coils, respectively, is represented by BMSmax,

the drive support unit is configured such that a relationship given by BMSmax<BMmax+BSmax is satisfied.
