NeuMotors 2000 Series Professional Multirotor Motor: 200-400 watts

 

 

Neumotors 2000 series outrunner motors are designed to be professional / military grade multicopter motors.  Our experience with numerous production UAVs and top aerospace manufacturers ensures  20xx series motors are the truly the best drives in their class.

All of the 2025 motors weigh in at 3.35oz and all feature high quality NSK bearings and internal cooling fans. Magnets are N42SH grade and winding insulation is rated for over 300F. Motors support multiple propeller mounting options.
  • Premium outrunner construction
  • 6mm adapter
  • 22 poles / 24 slots
  • 20,000 rpm max

 

 


2025: Multicopter motor 200-400 watt class


 

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.

 

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.

 

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.
