• Brushless DC Motors
  calling for fine surface finishes. Because they have no commutator, brushless motors are more efficient, need less maintenance, and can operate at higher speeds than conventional dc motors. High efficiency and small size are especially important for military, aircraft, and automotive applications...
• Software models motors in 3D
  the search. lt uses finite elements to model 3D fields in both translating and rotating electromagnetic devices. Claw-pole alternator/motors, for example, have highly 3D geometry and cannot be modeled in 2D. Previous analyses assumed a stationary rotor and currents that were all known and dc. Those...
• WD Bearings Application: Electric Motors
  are the brushed and brushless types, which use internal and external commutation respectively to create an oscillating AC current from the DC source. Industrial DC motors are commonly used as the drive for rolling mills to stimulate the action of hoisting up, pressing down, rolling, etc. Synchronous...
• Switch to 42 Volt Automotive Systems Brings Challenges and Opportunities
  Goldstein Group Communications, Inc. 1. SWITCH TO 42 VOLT AUTOMOTIVE SYSTEMS. BRINGS CHALLENGES AND OPPORTUNITIES. Qi Wang. Keithley Instruments, Inc. Switching to 42V automotive electrical systems almost seems like a no-brainer. But there's still a. lot of engineering and testing to be done...
• Simplifying Motor-Control Feedback Loops (epn)
  to DMC (digital-motor-control) solutions.01/07/2007. Reference: 23699. To control speed, angle or position of the rotor, a feedback loop is needed to sense the actual position during operation. Regardless of the motor type, a precision feedback loop is key for high efficiency. AC or DC motors have wide...
• 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...
• A recipe for A Slick Design
  a real vehicle. Prefix Corp., Rochester Hills, Mich., builds vehicle mock ups for ergonomic evaluations. Dc stepper motors coupled to precision linear bearings let evaluators experience dimensional representations of several different automotive interiors, even the dashboards, within a matter of seconds...
• Neo magnets boost fuel economy
  current draw and operating duty cycle. These two brushed-dc motors, using ceramic ferrite magnets, currently draw a combined continuous 35 to. Neo magnets boost fuel economy | Machine Design. Skip to Content. Home. Subscribe. Advertise. Contact. RSS. E-mail: * Password: *. Create new account...
• 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...
• Powder-metallurgy awards of distinction
  kpsi, respectively. MIM replaced an assembly made by laser-welding three wire-EDM parts. The single MIM part reduced final assembly time from 15 to just 5 min/unit. INDUSTRIAL MOTORS/CONTROLS & HYDRAULICS. Webster-Hoff Corp., Glendale Heights, Ill., and its customer, Norgren Automotive Inc., Mt...
