Document Type and Number:
Japanese Patent JP2018127925
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for reducing a current leaked from a motor to an outside of a container.SOLUTION: This pump (100) for fluid comprises: a container (10); a motor (11) having 3-phase coils (24, 26, 28); a pump mechanism (12) for sucking and emitting liquid by power of the motor (11); and a driving device (30) for driving the motor (11) by causing a current to flow through the motor (11). The driving device (30) causes the current to flow through at least two phases windings selected from three-phases windings (24, 26, 28) to generate heat while prohibiting rotation of the motor (11) beyond 360 degrees at a machine angle before starting the pump mechanism (12).SELECTED DRAWING: Figure 4
