Smoking motors

I have two different types of motors that smoke when at full throttle for 30-45 seconds. Based on my calculations, these motors are drawing about 70% amperage to their specified maximum. Is this typically a product of poor manufacturing or is this typical of brushless motors?

  • Not joking. What would cause smoking? You mention "decent setup". Can you be more specific? I have a properly rated discharge lipo, an ESC with enough amperage rating for the draw, and a motor.
    • winding errors in motors can do that, but most commonly it's too high load.

      The smoke is the enamel insulation of the copper wires and/or epoxy used.  - in any case - too much heat.

      What motors are you using (brand, model, KV)? , what propellers (size/pitch) ? and voltage (cellcount) ?  

      • Himodel AX2810-Q 900kv | 8045 | 4s (16.8 max voltage)

        NTM Propdrive 2826 1250V | 8045 | 4s (16.8 max voltage)

        • does both types smoke ?

  • Unless you are joking, it's very bad.
    Brushless have much better efficiency than brushed motors, in decent setup, you'll not feel any heat after a flight.
