  • The turbine: the air motor packing maximum efficiency
    What happens when the power from your drive unit simply isn't enough? When the motor for your. robot-controlled plant has to supply maximum power yet has to be physically very small? When it has to produce very high revolution speeds, yet be fit for continuous operation? The automatic processes
  • Limited-Angle Torque Motors
    for heat-seeking sensors, and power other systems that rotate through small angles. The rotor in a limited-angle torquer carries field magnets, and the stator supports armature windings (similar to the construction of conventional brushless motors). LATs, however, are wound single phase, unlike conventional
  • How to make bearings last in electric motors
    by electric arcing. Bearings coated with a ceramic insulating material stop electric arcing (inset). Hybrid bearings that incorporate ceramic rolling elements stop arcing as well. Rolling-element bearings in electric motors support and locate the rotor, maintain a small and consistent air gap between
  • The Case for Electric Motors in Unmanned Vehicle (.pdf)
    Unmanned Vehicles (UV's) that are small enough for a man to carry provide one of the more promising technologies for obtaining live situation intelligence. However, UV's developed for applications, including air (UAV), ground (UGV) or underwater (UUV), with gas or diesel engines may
  • BLDC Ducted-Fan Motor for Unmanned Vehicles
    situations, as air (UAV), ground (UGV), underwater (UUV) to have plenty of operational time. For small UAV's this means enough operational time for surveillance, sensing and swarming. For UGV's and UUV's, the ring motor can eliminate transmissions; allow larger payloads, and the ability to move faster
  • Pneumatic or servo?
    approximately 30-lb continuous force to well over 4,000 lb. Linear-motor forces only range as high as 2,700 lb, but at significantly higher velocities. Rotary possibilities use carriage assemblies that contain small leadscrews with a rotary mount. When mated with NEMA-17 motors and indexers, these assemblies
  • Hydraulic Pumps
    for a specific small job. In that kind of task, an air-powered intensifier lets the pneumatic system power
  • Improving Energy Efficiency in Pharmaceutical Manufacturing Operations Part II: HVAC, Boilers and Cogeneration
    individually, each measure may offer small savings, but combined they add up to significant savings and short payback periods. First, let s consider HVAC systems, which consist of dampers, supply and exhaust fans, filters, humidifiers, dehumidifiers, heating and cooling coils, ducts, and various
