    Can someone tell me whats the stalled amp. on the seat motors used in a 960?

    Thanks Michael

  2. There is no information in the Green Books covering 940, 960 and 850 models
    on stalled motor current. Generally if a motor stalls the control relay(s)
    will drop out to protect the circuitry. This will also happen if two motors
    are inadvertently selected together. I would suggest that you contact Volvo
    with a technical query, or measure the resistance of a motor, then divide
    the Voltage supply by that reading. Taking the supply as 14Volts should give
    a stalled motor current value very close to the actual value. I am intrigued
    by your reason for needing this information and would welcome the full story
    for the members of my registers.

    Cheers, Peter.

    Hi Peter
    I'm building a radio controlled submarine. It will use pumps to move it
    forward. These seat motors will provide the rotational energy for the pumps.
    The reason I need the amp. info. is due to the fact that I need to find a
    relevant battery.
    Regards Michael

    What you need to do is find a Model shop that sells and flies electric model
    airplanes. They should have what is called a Whatt Meter it will measure
    amps at various loads to help you determine which battery setup is best for
    the motor and load. Astro Flight Inc. in Marina Del Rey, CA. Manufactures
    the meter

    Sounds like a ripoff to me, just pick up a decent DMM with a 10A range, if
    that's not enough, get a precision 0.1 ohm resistor, put that in series with
    the motor and measure voltage across it, then use ohms law (simple, but
    there's calculators for it online too) to calculate the current.

    Your 100% right James, but I was not suggesting that he buy one. Second of
    all, if your in the field with 3 or 4 planes, with 6 to 8 different motors
    and 3 to 4 different props to work with its a handy little tool to have to
    tune things up and get what your looking for in performance.
