  • Rotor Testing with MCE (.pdf)
    around running speed and around the high frequency vibration known as rotor bar pass frequency. (RBPF). The FP and RBPF can be mathematically derived using the following equations: FP = P * FSlip. RBPF = RB * FShaft. Where: P = # of poles. FSlip = slip frequency. FShaft = shaft frequency. RB
  • Rotor Stator Mixer Design Shifts Into High Gear
    at extremely high tip speeds - up to 18,000 fpm. (Tip speed is commonly used as an indicator of shear and overall rotor/stator performance. Conventional single-stage rotor/stator mixers generally operate with tip speeds in the range of 3,000 4,000 fpm.). X-Series units are appropriate for applications

  • ESCAP (R) Ironless Rotor D.C. Micromotors and Step Motors:
    This chapter on dc micromotors is intended as a tutorial review of the major engineering considerations required for the proper selection and application of ironless dc micromotors and tachometers. Escap (R) Inonless Rotor DC Micromoters and Step Motors. Home > Reference Library > Escap (R) Motors
  • Development of Traction Motor for Fuel Cell Vehicle (.pdf)
    This motor adopted a salient pole type surface permanent magnet rotor, which enables it both to produce reluctance torque and to minimize the use of magnets. The inductance value is set at the limit value enabling output at the maximum rotor speed, which suppresses field-weakening current
