Abstract: A flexible, multilayer thin film capacitor comprises a flexible substrate and at least two electrode layers mounted on the substrate alternately with at least one dielectric layer. The dielectric layer may include amorphous hydrogenated carbon. The at least two electrode layers and the at least one dielectric layer are capable of acting as at least one capacitor, and the flexible substrate is capable of being manipulated so as to have a desired shape.

Abstract: Method of operating an electronically commutated motor, controlled by a board mounted electronic circuit, wherein current surges in such circuit are suppressed while dissipating heat associated with such suppression from motor structure as opposed to the control circuit. The heat associated with control circuit current surge suppression is dissipated into the bowels of the motor as opposed to being dissipated from a heat generating resistor mounted on the control circuit board as has been done heretofore. Illustrated structure includes current surge suppressing special winding turns on the motor core. Such special winding turns are connected with a known electronic control circuit so that power supplied to such circuit is transmitted through the special winding on the motor. Current surges associated with operation of the motor control circuit are then suppressed, during operation, by the special winding inside the motor.

Abstract: Motor vibration isolating arrangements and systems using such arrangements are disclosed. In preferred arrangements, leaf spring mounting arms have low torsional spring constants and yet strength to withstand shipping and handling loads. The mounting member spring constants for axial, radial and tilting vibration modes are selected in specific forms so that the characteristic vibration transmissibility ratios for these modes are each close to unity, but so that torsional mode vibration transmissibility is substantially less than unity. In particularly preferred arrangements, sheet steel having a martensitic grain structure is utilized. In some forms, the motor shell constitutes one weldable member and a holding plate is weldable. The spring material is protected by heat sinking from being softening and weakened by conventional welding processes. The heat sinking members also contribute to a very strong fastening scheme.

Abstract: The disclosure describes flexible motor mounting members particularly adapted for vibration induced flexing movement. In illustrated forms, leaf spring mounting arms have low torsional spring constants and yet have sufficient strength to withstand shipping and handling loads for motor-blower assemblies and to permit all angle motor mounting. The free end of the lug is specifically configured to prevent deformation and tearing, and the lugs are extremely easy to mount to a blower housing simply by deflecting the mounting arms (when necessary) with finger pressure so as to align holes in the mounting arms with previously provided holes in the blower housing.

Abstract: Disclosed subject matter includes flexible motor mounting members particularly adapted for vibration induced flexing movement combined with oscillatory movement about a pivot axis at a point of attachment on a blower housing or other support. Short but strong mounting members are provided that have low torsional mode vibration transmissibilities. Leaf spring mounting arms have low torsional spring constants and yet have sufficient strength to withstand shipping and handling loads for motor assemblies and to permit all angle motor mounting. The mounting member spring constants for axial, radial and tilting vibration modes are selected in specific forms so that the characteristic vibration transmissibility ratios for these modes are each close to unity. However, the characteristic torsional mode vibration transmissibility is substantially less than unity. In particularly preferred embodiments of the invention, sheet steel having a martensitic grain structure is utilized to form the mounting members.
