ELECTRONIC COMPONENT HOUSING CAPABLE OF DETECTING CUTTING FLUID ADHERING THERETO AND MOTOR DRIVING DEVICE INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a motor driving device capable of detecting a cutting fluid adhering to a housing of an electronic component.SOLUTION: A housing 20 for housing an electronic component 14 of a motor driving device 10 has a top surface 22c which inclines relative to a horizontal surface so as to guide a cutting fluid X adhering thereto. The housing 20 further includes a storage part 26 which collects the cutting fluid X guided along the top surface 22c. A scale may be provided at the storage part 26 so as to measure an amount of the collected cutting fluid X. The storage part 26 may be formed so as to be removed from the housing 20.SELECTED DRAWING: Figure 2
