Abstract: A strain relief plug to restrict movement of wires on a printed circuit board, the strain relief plug having an elongated stem along a vertical axis of the strain relief plug. The strain relief plug has an in-board flange defined by the elongated stem, the in-board flange configured to seat in a bore defined by the printed circuit board. The strain relief plug has an anchor defined by a first end of the elongated stem configured to prevent the strain relief plug from releasing from the printed circuit board. The strain relief plug has a bar defined by a second end of the elongated stem and transverse the vertical axis, the bar forming wire channels. The strain relief plug provides strain relief for wires on the printed circuit board of an electric motor in a vertical dimension resembling the thickness of the printed circuit board.

Abstract: A rotor having a plurality of laminations joined together and mountable on a shaft for rotation relative to a stator of a rotary electric machine arrangement has a solid section that surrounds an opening within which the shaft is receivable. The solid section includes an outside diameter, magnet receiving voids, and steps delimiting a plurality of pole spans from flux directing features at sides of each of the pole spans. Adjacent flux directing features between adjacent pole spans are disposed on opposite sides of scalloped areas or other such recesses, permitting cooling air flow past the rotor. The invention also concerns a lamination usable together with additional laminations to provide such a rotor, as well as an arrangement, such as an AC motor, generator, or motor/generator, including a stator and such a rotor.

Abstract: A printed circuit board has a solder joint inspection system including a substrate surface having at least one solder pad thereon, at least one conductor wire having an end attached to the at least one solder pad, and a first inspection feature. A first inspection feature is marked on the substrate surface adjacent to the at least one solder pad to define a conductor end zone on the at least one solder pad. The end of the conductor wire is in the conductor end zone when properly attached. The at least one solder pad may define a second inspection feature to mark an extent to which the at least one solder pad is covered by a flow of solder when the wire is properly attached.

Abstract: A torque-limiting safety circuit servo drive for AC permanent magnet motors including a three-phase inverter bridge, a first current sensor in series with a first motor phase, a second current sensor in series with a second motor phase, a third current sensor in series with the DC bus, and a drive control circuit that controls the six pulse-width modulated gate drive signals for the three-phase inverter bridge. The drive circuit has first and second safety channel STO inputs whereby either channel can shut down the three-phase inverter bridge, emits a signal set to represent the switching state of the three-phase inverter bridge, and modifies the switching pattern of the PWM to ensure the dwell times of PWM is sufficiently long to allow a valid measurement of phase current using the bus current sensor. First and second safety processors controls the first and second safety channel STO inputs, respectively.

The control circuit includes: a switching regulator configured to control a magnitude of voltage applied to a brake coil of the electromechanical brake; wherein said switching regulator includes at least one semiconductor switch, one diode, one capacitor and one inductor; the control circuit is configured such that, in operation, at least one signal from a process sub-system specifies the magnitude of the voltage for the brake coil; and at least one brake applying control signal from a safety sub-system can cause the brake coil voltage to be reduced to a level low enough to apply the brake by opening a switch and each brake applying control signal from the safety sub-system has a corresponding diagnostic feedback signal to the safety sub-system that indicates the state of the corresponding switch. A method and a system are disclosed.
