    eRC 480 Brushless motor

    I am trying to find some detailed info on the eRC 480 brushless motor. What I am looking for is the current draw and thrust numbers. I appreciate any information that you may have
    Thanks
    Rick

    There are two different ERC 480 motors,
    Here are the electrical specs for the motor and you can plug those into Ecalc or Mcalc with your prop setup
    to get the information.
    Or give me the prop size and manufacturer and battery setup . I can't give you the other information without knowing how you are going to load it and prop it.

    Motor rpm/v Io Rm
    2815 02D 900 .7 171
    2815-02C 1000 .8 140

    Jay,
    Thanks for the quick response. The setup in a 30" span 21 oz 3D (Goldberg Shock 400) that I am considering is the eRC480 10X6 APC style prop 3C 1300 MAH Lipo with a 25A speed control. I am open for any sugestions as I am somewhat new to the electric field.
    Thanks again in advance
    Rick

    Rick,

    With a 10 x 6 prop and a 3S lipo and the ERC 2815-02D motor, You never said which one.
    The performance looks like 65 deg climb at about 1600 ft min.

    That may be too much, I do not know what you are looking for.
    I guessed the wing area was around 400 sq in and the flying weight is 21 oz as you said.
    The current draw is 13 amps which is as much as the motor can handle.
    Is this the performance you want.
    This is near a sky rocket, the thrust is 26 oz.

    Rick,
    I also ran it with the ERC450BL and it is a little tamer.
    climb of 55 deg at 1500 ft a min on a 10 x 5 prop amps are 11.0
    This may be a little tamer if you like.

    WOW!!! That is an amazing bit of detailed info. What did you use to come up with that? I just got a copy of MotoCalc (as you suggested above), but have not had a chance to try it out.
    Thanks Again
    Rick

    Re: eRC 480 Brushless motor

    I use a program called Ecalc to figure this out.
    And plug in the motor specs that I have.
    Plus I have been using the program for about 15 years and modeling since 1960 and flying electric since
    1985.
    So not everything is in the program.
    Sorry.
    But Ecalc helps a lot.
    We sell it:
    ElectriCalc Program, Version 2.2 for WindowsElectriCalc computer software for Windows! Shows you how your motor, batteries, gearbox and prop will fly your electric airplane!...Product# ECALC2Price: $34.99
    It will not do EDF jets, and you have to put in your own specs for newer motors.
    The fellow who wrote it does not keep it up to date with the latest motors.
    Sometimes other user will update his information on his web site for it.
    Here is the website:

    he has a Demo, give it a try.
