<P>PROBLEM TO BE SOLVED: To provide a pump and a pump system capable of restraining a variation in a Q-H characteristic, capable of reducing a variation in a product, capable of detecting abnormality of the system in advance, capable of easily changing an electric current detecting resistance 104, and capable of enhancing convenience of the system. <P>SOLUTION: This pump 1 has a rotor for fixing a permanent magnet, a plurality of stator coils 12 arranged around the rotor, a control circuit (a motor driver IC 14) controlling current-carrying to the stator coils 12, and terminal parts P<SB>1</SB>to P<SB>5</SB>which is electrically connected to the control circuit and can be connected to an external part. The terminal parts have an electric current detecting terminal P<SB>6</SB>detecting an electric current flowing to the stator coils 12. <P>COPYRIGHT: (C)2007,JPO&INPIT |
