  1. [JAC016] Analysis of a Hybrid Stepper Motor

    This document introduces how the detent torque and stiffness torque can be calculated for a hybrid stepper motor.

  2. [JAC011] Pull-in/pull-out Analysis of a PM Stepper Motor Using a Control Simulator and the JMAG-RT

    This note presents how JMAG-RT can be used to calculate holding torque and coil inductance that varies with current. The result is the JMAG-RT motor model used as a reference for …

  3. [JAC004] Sound Pressure Analysis of a Reactor

    This Application Note shows an example of an evaluation of a reactor’s sound pressure when a part of a spacer has been removed.

  4. [JAC002] Cogging Analysis of a PM Linear Motor

    This note presents how to obtain cogging torque, a cause of thrust variation, and evaluate the thrust force and attraction force during drive.

  5. [JAC001] Torque Characteristic Analysis of a Three Phase Induction Motor

    This Application Note introduces a case example of how to obtain the current density distribution of an auxiliary conductor and its rotation speed versus torque characteristics.

  6. [JAC009] Sound Pressure Analysis of a Loudspeaker

    This Application Note presents how the frequency characteristics of sound pressure can be obtained using the constant Lorenz force on the voice coil, regardless of the frequency.
