    摘要: A permanent magnet synchronous motor driving system includes: 1) a permanent magnet synchronous motor, and 2) an inverter. The permanent magnet synchronous motor includes three phase terminals. A resonant frequency is generated between an inductance and a ground electrostatic capacitance which are measured between the following: a) one of the three phase terminals of the permanent magnet synchronous motor, and b) a ground. The inverter drives the permanent magnet synchronous motor. The inverter generates a carrier frequency. The resonant frequency of the permanent magnet synchronous motor is free from a conformance with the carrier frequency of the inverter and is free from a proximity of the carrier frequency of the inverter.

    摘要: A cable mounting structure for an electric apparatus is provided which ensures sealing properties, such as waterproof properties and dustproof properties, and which can effectively contribute to downsizing, while easing restrictions on the size of a connecting tool mounted on one end of a cable connected to an electric apparatus body. The cable mounting structure comprises a housing (10) for accommodating an electric apparatus body, a cable (11) connected to the electric apparatus body via a second connector (12) or the like, a grommet (20) mounted on the cable (11), a recessed housing section (15) provided in the housing (10), and a lid (30) for closing the recessed housing section. The recessed housing section is formed in a closed-bottomed tubular shape recessed inwardly of the housing. A grommet mounting hole for fixing the grommet (20) thereto is formed in a peripheral wall section (15a) of the recessed housing section, and a pass-through section (31) through which the cable is passed is formed in the lid. The connecting tool is disposed within the recessed housing section, and the pass-through section is positioned to the grommet.
