    INCREASED DURABILITY
  • SUPERIOR QUALITY OF MOTION

    ECM motors have zero cogging and smooth torque for a superior quality of motion compared to conventional machines.

    • Cogging is eliminated because ECM motors are air core machines with PCB Stators which have no iron

    Exceptional pointing accuracy and precision

    • Ability to create actuators with absolute resolution
    • 24-bit encoder = 16,777,216 discrete positions

    SUPERIOR MOTION
  • HIGH TORQUE DENSITY

    PrintStator designs electric motors that deliver more torque with less mass.
    Up to 30% of the mass of many competing designs.

    • PrintStator’s optimal use of copper and other raw materials results in extremely torque dense machines.

    Motors with high power density but minimal axial-length and weight

    • The flexible form factor of ECM motors also enables extremely compact motor+gearbox integrations.
    • Stacking multiple PCB Motors on the same shaft is also possible.

    HIGH TORQUE DENSITY
  • LOW NOISE AND ELECTROMAGNETIC INTERFERENCE

    PCB Stator Motors produce significantly less electromagnetic interference and acoustic noise
    Up to 30db quieter

    • ECM coils are fully encapsulated in composite structure, eliminating acoustic noise and reliability problems caused from vibration and other forces on traditional stator windings
    • Zero cogging motors eliminate mechanical excitation of attached structures as a source of noise

    ECM motors are considered to produce the least EMI of any competitive motor

    • Harmonics do not excite mechanical modes in the motor because it’s not used as a filter

    LOW NOISE AND EMI
  • INCREASED THERMAL PERFORMANCE

    PrintStator embeds patented thermal features in each motor design for safe continuous operation.

    • Effective thermal features enable motors that do not require active cooling
    • Utilizes a continuous copper path from the parts of the stator, where losses originate, to the case where heat can be rejected to ambient
      • These non-current-carrying portions of the PCB copper function as “heat pipes”
      • These non-hollow “heat pipes” conduct heat from the center of the stator to the outside edge, where the stator is clamped into the case
