  • Intelligent Thermal Management Using Brushless DC Fans
    . The limitations become apparent,. The types commonly used in consumer electronics. however, when driving larger fans at higher power. resemble small axial-leaded capacitors. Surface mount. levels or when attempting to idle fans at low speeds in. or screw mount types are also available. Due to certain. order
  • Fan Efficiency, An Increasingly Important Selection Criteria
    Corporation – NMB Technologies Corporation, a Minebea Group Company, is the world's largest manufacturer of miniature precision ball bearings and a volume leader in the design and manufacturing of precision electro-mechanical components, including cooling fans and blowers, precision small motors
  • Electronically-Controlled Hydrostatic Fan Drive Systems (.pdf)
    (hysteresis) is very small, approximately 1°C. This. permits precise control of the coolant temperature with. minimal temperature fl uctuations, even when there are. extreme changes in the engine load. 5. Reduced Engine Wear — Fig. 5 shows the extent to which. cylinder wear in an engine in infl uenced
  • Airflow Performace and Speed at a Glace: Fan Curves and Optimum Operating Points (.pdf)
    of their construction, all small fans have relatively small low-performance drive. motors. This means that depending on the different loads placed on them their speed and power consumption. alter dramatically. With axial fans for example the maximum speed is achieved at the greatest flow rate but at the. same time
  • What Is The Correct Type Of Fan: Axial, Radial, Diagonal? (.pdf)
    into the fans). Press News. The theory and practice of small fans (1). What is the correct type of fan: Axial, radial, diagonal?. Fans are as varied in their construction as they are in their applications. These "air-donors " are primarily. differentiated according the physical principle of the transfer
  • Fan Variants: What Type Of Drive, What Type Of Material? (.pdf)
    , the speed of the motor should only demonstrate minimal fluctuations,. even though the torque requirement of the fan is changing dependent on the operating conditions. Modern fans are now generally all equipped with small, electronically commutated DC motors, also termed EC. motors. This kind of simple
  • Linear Voltage Fan Speed Control Using Microchip's TC64X Family
    of a transistor. increased and may require heatsink mounting. Also,. in series with a fan, can be small and inexpensive. most fans cannot be operated at less than half the full-. because it is either fully on or completely off. This effi-. rated supply voltage, thereby limiting the fan speed. cient control
  • White Paper: Reliability of Air Moving Fans, and Their Impact on System Reliability
    briefly discusses the role of temperature on insulation aging, the difference. between natural vs. forced air convection, reliability modeling for air-moving fans and. finally how PM increases the reliability of a UPS system. Liebert recommends replacing small. flat fans after 5 years of service
  • Universal Motors: Timeless Performance
    with a friend: Universal Motors: Timeless Performance. The universal motor, an often maligned old workhorse, is a particularly adaptable motor, and still proves very useful in many applications. When an application calls for high starting torque, power, and speed - all combined in a small, lightweight
  • Bearing Systems for Fans: Ball Bearings Or Sleeve Bearings? (.pdf)
    tight tolerances for the bore of the bearing and the shaft diameter. Furthermore the steel shafts must meet high demands with respect to the surface quality. The film of lubricating. oil in sintered bearings is only a few µm thick, so that even small degrees of surface roughness can penetrate
