  • Encoders for Brushless Motor Commutation
    The process of steering current through the appropriate motor windings in order to produce output torque is called commutation. In brush motors, commutation is accomplished electro-mechanically via brushes and the commutator. In brushless motors, commutation is performed by electronically steering
  • Sensorless Brushless DC Motor Control with PIC16
    the many advantages to a BLDC motor no speed regulation. over a brushed DC motor, we can enumerate the following: HARDWARE * The absence of the mechanical commutator The hardware for a BLDC system can be decomposedallows higher speeds into the following sections: * Brush performance limits
  • 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
  • Using Inverter Technology in the Motor Fusing Industry (.pdf)
    difficult, time consuming, and therefore, expensive, but also emitted dangerous lead pollutants into the atmosphere. Furthermore, if a soldered armature's motor stalled or overloaded, there was a chance the solder might remelt and "spit out" contaminating the commutator and damaging the armature's
  • Conducting Quality Audits in Offshore Motor Components Factories
    Many motor manufacturers are going offshore to purchase or manufacture motor components. These include commutators, brushes, armatures, magnets, laminations, etc. Offshore factories vary considerably in the robustness of their process capabilities and quality systems and visitors are at a clear
  • Reasons for Turning to Slotless DC Motor Technology
    . mechanism that would wear and eventually result in motor failure, brushless motors could be relied upon. to deliver performance over time. As for other advantages, conventional wisdom held that brushless. motors provide high speed and fast acceleration, generate less audible noise and electromagnetic
  • Proper Motor Brush Selection When Brush Life is a Concern
    One of the most critical parts of this type of motor is the interface between the brushes and the commutator. Poor material selection and improper design considerations can affect both the life and the performance of an electric motor. This post briefly covers the factors which contribute to brush
  • How To: Reduce Noise Output from a Brushed Motor
    Noise is often the single toughest challenge faced by design engineers when developing products especially in medical applications. The inherent noise issue with many types of motors is the brushes. Brushes create mechanical and electrical noise due to friction against the commutator, as well
  • Where adhesives beat mechanical fasteners
    the leads with low-mass LCMs in a hand-tool motor lets designers eliminate some postjoining finishing. Lenses of fog-light nacelles were originally bonded and sealed to the housing using silicone. However, production was slow (24 hr) because of long cure cycles. Switching to LCM adhesives not only reduced
