Title:
POWER CONVERSION DEVICE INTEGRATED MOTOR
Document Type and Number:
Japanese Patent JP2016019399
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power conversion device integrated motor capable of improving cooling efficiency of a power conversion device while sealing a power conversion device side housing.SOLUTION: A power conversion device side housing 3 and a motor side housing 4 are sealed by sealing plates 5i and 5m of a double structure formed in a housing coupling member and cover member 5. In the housing coupling member and cover member 5, a communication hole 15 opposite to a radial direction of a rotary shaft 6 of a motor 2 is formed between the sealing plates 5i and 5m of the double structure. Therefore, a natural convection that is generated by positioning the communication hole 15 in a vertical direction, is generated between the sealing plates 5i and 5m of the double structure and as a result, the sealing plate 5i at the side of the power conversion device and the sealing plate 5m at the side of the motor are cooled, such that cooling efficiency of a power conversion device 1 is improved.SELECTED DRAWING: Figure 1
