1700 SERIES BRUSHLESS MOTORS

1700 Series Motors:

43mm OD 1700 series innrunner BLDC motors feature a large diameter rotor in a fixed enclosure.  High diameter to length bias achieves the high torque advantages of an outrunner with the mounting and operational advantages of a non-rotating enclosure.

 

  • Inrunner construction
  • Large diameter rotor for high torque
  • High speed operation – 35,000 rpm
  • 8poles / 24 slots
  • 5mm shaft

Options:

May be mated with P32 gearboxes for very high power-to-weight drives.

May be ordered with a sealed enclosure for water and dust proof operation.

    POWER RATINGS (Watts):

    • Continuous rating is the power the motor can deliver while maintaining the external housing temperatures below 100C.
    • 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.
