摘要： The present invention relates to electric appliances for personal care, in particular electric shavers, comprising a drive unit having first and second drive components adapted to magnetically interact with each other, and a magnetic shielding at least partially surrounding the drive unit. Said magnetic shielding is formed by structural parts supporting the drive unit and/or transmitting drive movements of the drive unit, wherein such structural parts are made of a soft magnetic material. More particularly, a mounting frame and a transmitter frame together form a magnetic shielding cage which is movable as the mounting frame and the transmitter frame are movable relative to each other.

摘要： A motor-driven compressor includes a housing, a compression portion, and an electric motor, a drive circuit, a circuit housing, a control circuit, a communication lead, and a metal shielding member. The compression portion and the electric motor are received in the housing. The circuit housing is arranged outside the housing and defines an accommodation chamber that receives the drive circuit. The control circuit is configured to control the electric motor by controlling the drive circuit. The communication lead is connected to the control circuit and drawn from the inside to the outside of the accommodation chamber. The metal shielding member is arranged in the accommodation chamber and covers the communication lead. The circuit housing includes a metal shielding portion, which is electrically grounded. The shielding member is electrically connected to the shielding portion.

摘要： The disclosed apparatus provides a simple and low cost solution of reducing voltage stress on AC motors and cables in VFD fed motor systems without connecting apparatus to live circuits. Disclosed examples include apparatus to couple a motor drive to a motor, including a cable with a first end coupled with an output of a motor drive, a second end coupled with a motor, a plurality of conductors to convey an output signal of the motor drive between the first and second ends to drive the motor, and a plurality of shields, with a conductive junction to couple tap points of at least two of the shields together. Resistors can be used to connect the tap points to the conductive junction to provide an impedance in series with the corresponding shield to reduce voltage stress to the motor or the cable. In certain examples, the shields include a semiconductor material to provide an impedance between the first end and the conductive junction to reduce voltage stress to the motor or the cable.
