  • Electrolube's ER2223 Resin Protects Stator in Next Generation E-Vehicles
    Electrolube were recently approached by a manufacturer of electric motors for the next generation of electric vehicles; their requirement was specifically for a resin to electrically insulate the stator coil.
  • Reed Switch Test Coils
    All of our Reed Switches are 100 % tested in our Standard Test Coils and measured in ampere-turns (AT). Simply stated, we have coils wound in a specific coil form, with a given number of turns. We supply a ramp of current to the coil. When the contacts close, we calculate the number of turns
  • Auxiliary Coil Excitation (PMG-I)
    Cat (R) generator sets assembled at the Caterpillar facility in Piracicaba, Brazil, known as Power Systems Brazil (PSB), use alternators that feature an auxiliary coil (or auxiliary winding) and permanent magnets in the exciter stator. This provides the benefits of an alternator fitted

  • Driving a Solid-State Relay with the L100-MFR2 Series (.pdf)
    Sometimes it may be necessary to drive a relay to activate certain external devices such as electromechanical brakes or clutches. Typically electromechanical relays have a 24VDC coil voltage. In the case of the L100-MFR2 Series of Inverters, such voltage is NOT available on any of the inverter
  • Stepper Motor Theory
    motors incorporate a permanent magnet rotor, coil windings and magnetically conductive stators. Energizing a coil winding creates an electromagnetic field with a north and south pole as shown in figure 1. The stator carries the magnetic field which causes the rotor to align itself with the magnetic
  • Highly Conductive Insulation for Large, High-Speed Machines
    Silicone-impregnated fiberglass insulation has long been used as stator-coil electrical-insulation for low-voltage, direct current, traction motors. Silicone-based insulation is particularly suited for this application because its thermo-oxidative stability ensures excellent long-term resistance
  • Latching Relays, How They Work
    Latching relays are electrically operated switches that change state (switch) with a pulsed voltage input to an actuator coil. Once they have changed state, they remain in that state without continuous application of the actuator voltage. Subsequent return to the original state is caused
