32XX SERIES BRUSHLESS INRUNNER MOTORS

32XX SERIES QUICK LOOK:

This series’ high diameter to length bias achieves the high torque advantages of an outrunner with the mounting and operational advantages of a non-rotating enclosure.

  • 79mm OD
  • Inrunner construction
  • 10,000 RPM max
  • 12 poles / 36 slots
  • 8mm shaft

OPTIONS:

  • Finned case
  • Waterproof case
  • May be mated with P42 or P62 gearboxes for very high power-to-weight drives.
  • Finned case
  • Stator can be skewed for reduced cogging and acoustic signature
  • US component sourcing and assembly available

MOTOR SELECTION:

The motor sizes and kVs listed above are the most common for this particular motor range. Custom sizes and RPMS are usually available.  Please contact us for more details if you don't immediately see the solution you are seeking in the tables above.

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.

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.
