• China ups the motor ante
  China's motor manufacturers are well versed in small, standard motors. Now they're setting their sights on steppers and servos. Chinese manufacturers have been making motors for years. The majority of these have been small ac and dc units for electric tools, toys, and other high-volume applications...
• Getting torque-to-inertia right
  The case of a pulsating-load testing machine shows how to ballpark qualities that are important for deploying electric motors. A 15-hp, E-182 frame brushless-dc motor from Powertec uses neodymium permanent magnets on the shaft and a conventional three-phase stator winding. An internal resolver...
• Modeling optimizes drive systems
  , drive electronics, and a mechanical transmission. Integrating electronics such as sensors, actuators, and power converters into a hostile automotive environment makes modeling a necessity. In the electric powertrain, the ac induction motor is driven by an inverter and controller employing a vector...
• First SOIC8-Packaged Hall-Effect Current Sensor With Integrated Current Path Introduced
  is targeted to meet the needs of the industrial, consumer, communications and automotive markets. End applications including motor control and protection, small electric vehicles, battery monitoring and charge control, power distribution and monitoring, and personal UPS systems. This newest family is priced...
• "Dad, Can I Take the Car for a Swim?"
  was picked for its open roof, small size, light weight, and good looks. The first step was replacing the engine with three electric motors in the rear. One propels the car on land. The other two supported by jet drives in front drive the screws. Louvers open and close to control water intake. The jets...
• Transparentportation: Concept car gets "all clear"
  After making his latest prototype all but disappear, Swiss automotive visionary Frank K. Rinderknecht may be the Houdini of concept cars. Rinderknecht's "eXasis" has a transparent body and floor made of polycarbonate (Makrolon) from Bayer MaterialScience (BMS) AG. The Rinspeed Inc. creation, built...
• No-static plastics
  energy created by electromagnetic fields that are radiated or absorbed by electrical components. Sources of EMI/RFI come from computer circuits, radio transmitters, electric motors, and lighting. Insulators. Partial insulators/partial conductors. Conductors. INSULATIVE. STATIC DISSIPATIVE. CONDUCTIVE...
• Ecofriendly Polycarbonate and Ecofriendly Castings
  , and other parts for several major automotive companies. How to slow the growth of electricity consumption. Energy-efficiency programs in the U.S. could slow the growth of electricity consumption by 22% over the next two decades, says the Electric Power Research Institute (EPRI), Palo Alto, Calif...
• In search of a small 42-V relay
  As cars and trucks make the switch to 42-V power, engineers are redesigning and miniaturizing the electric relay switch. Cars and trucks are carrying more electrical systems than ever, from power windows, seats, doors, and locks, to navigation modules, CD players, and Internet connections...
• 'Low-surge' inverters
  . Whitepapers. Reference Centers. 'Low-surge' inverters. October 7, 2004. New circuit topology lets ac servodrives keep a lid on surge voltages that can otherwise shorten motor life. Printer-friendly version. Rafi Wilkinson. Yaskawa Electric America Inc. Waukegan, Ill. The G7 inverter provides both open-loop...
