ECM’s patented PCB stator technology has been integrated in motors with efficiencies as high as 96%.

• lower operating costs
• extended battery life
• lower carbon footprint

• Optimizing the copper geometries and thickness of traces in PCB stators for the targeted reduction of efficiency losses - resistance and eddy current
• Optimizing/ restraining all other design parameters for the most optimal efficiency result

Unique form factor of PCB Stators enables remarkably compact, ultra-thin and lightweight motors.

• PrintStator optimizes the use of copper and other materials to provide superior torque with less mass.
  • Up to 70% lighter
  • Up to 80% less raw materials
  • No iron in PCB stators

• PrintStator creates Low Volume Motors for Compact System Integration
  • Planar form factor: Remains ultra-thin even at large power ratings
  • Compact integration with torque multipliers

The ECM PCB Stator’s continuous coil design and fully encapsulated windings eliminate many of the failures common to traditionally wound motors and increase life expectancy.

• ECM motors have been run through HALT testing with impressive results
• Weather resistant and fine in oil and salt-water environments

Reliable, Robust Design for Longer Motor Life

• Durable design: Less moving parts, less vibration
• Durable material: FR-4 is a composite of glass fiber used in military applications, including missile/rocket PCB’s

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

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.

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

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

PrintStator reduces design cycle time and improves design flexibility, ultimately producing the most optimized solution for every application.
