  • Generator Winding Pitch and Harmonics - Caterpillar (.pdf)
    This engine data sheet will discuss the advantages and disadvantages of various winding pitches and how it affects generator performance. It will also discuss the effects on harmonic content, waveform, paralleling, electric motors, switchgear instrumentation, and protective relaying.
  • Overheating Electric Motors: One Root Cause of Insulation Failure
    application instead of one or two components, true troubleshooting solutions become available. Maintenance experts agree that excessive heat causes rapid deterioration of the winding insulation within motors. The common rule states, for every 10oC of additional heat to the windings, the insulation life
  • AC Motors
    electric motor and consists of two basic electrical assemblies: the wound stator and the rotor assembly. The induction motor derives its name from currents flowing in the secondary member (rotor) that are induced by alternating currents flowing in the primary member (stator). The combined
  • 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
  • Brushless dc Motors in Medical Applications
    on the prescription list for a variety of applications. By definition, a brushless-dc motor is a synchronous electric motor powered by a dc-power source. While derived from the brushed-dc motor, an electronic commutation circuit takes the place of the standard commutator and brush assembly. In terms
  • Lorentz forces shrink motor size
    a 14-in. e-Torq motor can deliver more than 700 N-m torque and speeds to 6,000 rpm. Traditional brushless electric motors are designed around principles based on Faraday's Law which defines the behavior of attractive and repulsive forces between two inter-acting magnetic fields. For example, permanent
  • Sensored BLDC Motor Control Using dsPIC30F2010
    on BLDC motor details. BLDC motors are basically inside-out DC motors. In a DC motor the stator is a permanent magnet. The rotor has the windings, which are excited with a current. The current in the rotor is reversed to create a rotating or moving electric field by means of a split commutator
  • How to speed up dc motor selection
    Recent advances in electric motors and controllers improve their speed, acceleration, controllability, and reliability, while allowing designers a wider choice of power and torque. Selecting a fractional hp dc motor is easier when you know how to handle motor constant . Guidelines used by experts
  • Lamination-Free Motor Reduces Battery Power Consumption 30%
    during the past decade, electric motors, especially low horsepower motors, have had limited efficiency gains. This is largely because traditional motors utilize electromotive coils designed with copper wire windings supported by iron laminations, which have inherent inefficiencies. However, a new
  • The next step in rapid prototyping
    in the use of RP parts. The electric motor windings, shaft, and fan provide an example of parts produced on machines from Objet Geometries. The casting core for a hydraulic component was made of Z-Cast from Z-Corp. by technicians at Griffin Corp. Traditional core material would not have allowed the detail
