Abstract: A printed circuit board having an electrically insulative layer and a conductive solder pad. The conductive solder pad is disposed at least partially over the electrically insulative layer, and defines a solder contact area. The solder contact area is configured for making an electrical connection to an electrical component via laser soldering. The printed circuit board further includes a solder mask coating the conductive solder pad and defining an exposed area of the conductive solder pad. The conductive solder pad protects the electrically insulative layer from incident heat during the laser soldering by extending a length underneath the solder mask along a periphery of the exposed area.

Abstract: Networked automation systems having electric actuation from a high voltage source. The electric actuator includes a switch mode power supply coupled to the high voltage source as a principal power source. The networked automation systems include a controller device having an output network port wired to an input network port of the motor drive. The controller device is also coupled to an auxiliary source of power. Thus, a regulation circuit of the switch mode power supply can be coupled to the auxiliary source of power, thereby providing power for the regulation circuit at start up.

Abstract: A rotor for an electric motor with improved oscillation settling characteristics has a shaft rotatable about a longitudinal axis, a rotor section, disposed on the shaft for rotation together with the shaft, and, in certain arrangements, a permanent magnet disposed adjacent to the rotor section for rotation together with the shaft. The rotor section defines a recess around the shaft, extending from an end of the rotor section axially toward the opposite end of the rotor section, or the permanent magnet, if it is provided, and at least one mass is secured to the rotor section within the recess by a layer of deformable damping material, such as a dielectric gel. The rotor is particularly appropriate for use in a hybrid stepper motor, a variable reluctance motor, or a permanent magnet brushless motor, and a process of assembling the rotor is also referred to.
