  • Success Story: Electromechanical Assembly
    or perpendicularity of the base plate. At the same time, the tube needed to fit interference free with the electrical coil windings.
  • Stepper Motor Theory
    Motors convert electrical energy into mechanical energy. A stepper motor converts electrical pulses into specific rotational movements. The movement created by each pulse is precise and repeatable, which is why stepper motors are so effective for positioning applications. Permanent Magnet stepper
  • Dynamic sensing with LVDTs
    and displacement of a shaker head in a vibration tester. The core movement accurately represents mechanical displacement, with typical linearity of 0.025% of full range. A linear-variable-differential transformer, or LVDT, is basically a transducer that converts mechanical motion into an electrical
  • Transformer Basics (.pdf)
    in the manufacture of layer-wound transformer coils. A layer-wound coil consists of single layers of wire separated by layers of insulation. Here, the insulation serves a dual purpose: it is a support platform for the wire and electrical isolation from parts having opposite polarity and other conductive materials
  • That's a Wrap
    A creative wrapping technique builds structurally stable and well-insulated coils for a new fusion reactor. A challenge faced by Princeton Plasma Physics Laboratory (PPPL) researchers was to devise both electrical isolation and structural support for conductive coils that will see 2 kV when
  • Why Motors Fail Part 1.
    components. Contamination is never good for electrical components. Contamination can destroy motors in three ways: Some airborne particulates are very abrasive. Motor coils flex when in use and contamination with abrasive particles eats away the wire enamel. Some substances, such as salt or coal dust
  • What are Brushless DC Motors and how do they work?
    /torque properties, they are ideal for many applications. Compared to brush DC motors, brushless motors have longer life, higher efficiency, less maintenance, and low electrical noise generation. The only drawbacks are that BLDC motors cost more and require complex controls. ARC Systems, Inc
  • Coreless DC Motors
    in conventional motors is caused primarily by the release of stored energy in the armature inductance upon commutation. Excessive arcing produces electrical noise and reduces the life of brushes. Coreless motors are classified by rotor shapes as cylindrical or disc. Cylindrical rotors are further divided
  • May the force loop be with you
    control. The force is created by applying pressure to a working gas or fluid in a hydraulic or pneumatic cylinder. A piston then converts the pressure to a force applied to the load. Another open-loop method uses permanent-magnet motors. An electrical current is applied to the motor windings
