• WD Bearings Application: Electric Motors
  in large machineries, fans, pumps, compressors, rolling mill and some miniature equipments. Therefore, WD energy bearings, with high speed, low noise and long life, are available in synchronous electric motors. Asynchronous Electric Motor. Asynchronous electric motors, with compact design, low...
• Software Review: FEA for Electric Motors
  accuracy and precision. So we tried Opera Electrical Machines Environment, an applicationspecific variant of a general-purpose electromagnetic FEA tool. It helps speed the building of models with ready-to-use templates for common motor types. The software works by presenting a high-level frontend...
• Mathematical models for electric hydraulic drives
  of hydraulic drives in factory automation. On one hand, hydraulic drives follow basic laws of hydrostatics. On the other hand, the machines they work with often operate at high pressures and speeds, placing them in a dynamic regime. So the laws of hydrodynamics don't fully explain the machines' operation...
• Off-Road Electric Drives Gain Traction
  speeds inherent in diesel engines. "Traditionally, you have to rev up the engine to get more torque," says Rinaldo. "But the electric motor is just the opposite; from 0 rpm we get high torque. At start-up we boost the diesel engine with the electric motor, which gives us much faster machine response...
• Mighty motors
  , but not at low speeds. However, new synchronous motor designs using permanent magnets make it possible to have low speed and high torque in one package, eliminating gearboxes and other mechanical components. Traditional synchronous motors rely on rotor windings and brushes for excitation. Newer...
• Wheel may fly high
  /epoxy composites for the flywheel's rotor, low-loss magnets for the bearings, high-speed electric motors and generators for energy conversion, and computer algorithms for motion control. This particular flywheel, enclosed in an aluminum vacuum vessel, consists of a high-speed brushless dc motor, upper...
• Dynamics of Hybrid Stepper Motors
  outside diameter. A permanent magnet between each laminated stack pair creates a north and south pole oriented along the motor shaft axis. Conventional electric motors rotate continuously, but stepper motors rotate or step in fixed angular increments. One revolution involves the motor taking a specific...
• 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...
• Tiny Motors Make Big Moves
  With only one moving part, piezoelectric motors one-up conventional motors, gears, and drive screws in miniature applications. The plethora of shrinking devices spurred by new technologies need a special type of miniature electric motor that fits their small size. Instead of the typical magnet...
• Software models motors in 3D
  As an engineer working with electric motors and generators, I've kept an eye open for software that more completely analyzes these machines. The geometry is for one pole of six in a claw-pole alternator. The computed magnetic flux density shows its distribution at Maxwell Version 10 may end...
