Parvovirus B19. Parvovirus B19 infections in children present as a viral exanthema, and in adults as a cause of arthralgia and arthritis. The incubation period is 7â10 days with non-specific flu-like symptoms in the first week followed by arthralgias or arthritis in up to 60% of patients in the second week.
Variable Torque Motors - American Made Efficiency. One of the largest down-sides to electric motors is their inherent efficiency range and, in hybrid systems, the drag they can create on the drive train.
AC Inverter/Vector Duty Motors. Industrial electric motors from Baldor are available for most general purpose applications and processes. However, some AC Variable Speed applications require constant torque at zero speed. Inverter/Vector motors are designed specifically for adjustable speed applications in a standard NEMA Frame motor. Additionally, the AC Inverter/Vector Motors can be ran across the line for bypass operation and can deliver a 1000:1 Speed Range in a standard TENV or TEBC Enclosure.
