LEAD TIME

Neutronics assembles motors to order.  Most motors in this series are ready to ship from our San Diego office within 1-2 weeks.  Lead time varies with quantity, customizations, and supply chain considerations.  Rush orders may be available.

Please email us to confirm delivery estimates for your motor needs. info@neutronics.com

MOTOR KV:

The motor sizes and KVs listed above are the most common for this particular motor range. Custom sizes and  KV (RPMs per volt) are usually available.  Please contact us for more details if you don't immediately see the solution you are seeking in the tables above.

KV is the term used in the brushless motor workspace to specify the number of rotations per minute that a motor will turn for each volt applied to the motor/ESC with no load on the motor.

Neutronics specifications are +/- 5%.

For a more complete discussion of KV, please go to our KV FAQ page.  

POWER RATINGS (Watts):

  • Continuous rating is the power the motor can deliver while maintaining the external housing temperatures below 100C.
  • MAX power is achieved at max RPMs and voltage, not at a partial throttle or reduced voltage.
  • MAX power rating is the power the motor can deliver beginning with motor at a temp of 20C until it reaches it's limit temperature of 100C.
  • The ratings are therefore dependent on a number of variables including air flow, ambient air temperature, contact cooling etc. Each application will present different variables.  

MTBF RATINGS:

When used within the constraints described above, BLDC motors' primary "wear" item(s) are the bearings supporting the shaft. Bearing life is inversely affected by speed, temperature, and radial and axial loads.  While an MTBF figure can be generated, it would be rendered invalid by excursions beyond prescribed temperatures or load limits - such as prop strikes, or side loads.  MTBF must be determined on a case by case basis, and even then, it would be subject to numerous exceptions.

MAX VOLTAGE

Limited by kv (RPMs per volt) times the applied voltage.  Max voltage must be kept below the voltage which will spin the motor over max rpm for the motor series.

MAX AMPERAGE

See power ratings above.

COMPONENT SPECIFICATIONS

  • Winding temperature:  -- 180C
  • Magnet grade: - 180C UH grade
  • Bearings:  Japanese SPB bearings

CONTROLLER SETTINGS: TIMING

  • APD controllers automatically adjust timing for optimum efficiency
  • Recommend low timing for controllers that require configuration

Pole Count vs. Pole Pairs

  • Neumotors lists the number of poles in a motor rotor. Example: N S N S would be a four pole motor.
  • Some ESC manufacturers use the term "pole pairs" which refers to the number of N and S pairs.  Example: N S N S would be a 2 pole pair motor.
