Title:
ELECTRIC FLUID PUMP
Document Type and Number:
Japanese Patent JP2015053829
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a new electric fluid pump that can be miniaturized by shortening the length of a drive control part in the axial direction thereof.SOLUTION: A jumper wire guide by which jumper wires for at least two phases or less are guided, and a jumper wire guide by which all jumper wires for three phases are guided are provided, the height of the jumper wire guide is set in accordance with the number of guided jumper wires, an opening part is formed by cutting a part of a holder located in the vicinity of the jumper wire guide by which the jumper wires for two phases or less are guided, and electrical components are disposed in close vicinity to the jumper wire guide by which the jumper wires for two phases of less are guided through the cut part. Since the electrical components such as capacitors, inductance elements, or the like are disposed in close vicinity to the jumper wire guide by which the jumper wires for two phases or less are guided, the electrical components can be disposed by bringing them near to the stator part side by the length of a guide groove for guiding the jumper wire for one phase, and the length of a drive control part can be shortened by this length.
