    This doesn't look right to me gearing doesn't make a difference?

    DAVID BROWN GEARED ELECTRIC MOTOR.
    RADICON MOTOR WITH DAVID BROWN GEARBOX.
    MOTOR INPUT - 1385 RPM.
    GEARBOX OUTPUT - 60 RPM.
    MODEL - MO42022.
    3PH, 0.37KW.

    If it's 3HP = 2.23800000 KW

    If it's 0.37KW = 0.49597855 HP

    Have I got it right KW x 1.34 = HP?

    doesnt that say 3 PHASE not 3 HORSEPOWER??????????


    you are right in saying 0.37kw is a gnats cock under 1/2 horse though...

    750 watts to a horse power basically. so a 0.37kw motor is half horse. 0.55kw is 3/4 horse. 0.75kw is 1 horse. 1.1kw is a 1 1/2 horse. 1.5kw is 2 horse. 2.2kw is 3 horse. 3kw is a 4 horse etc

    Hello Justme,

    no, motors are rated as total load of all three phases, for your information is worked out by square root of three times line voltage (415v for small motors) times full load current times power factor (normally taken as 0.8)

    Is that like - KW x 1.34 = HP or HP x 1.34 = KW?

    Cause there are various HP's, Oh yes.

    There's Horsepower (Metric, DIN, PS)
    or
    Horsepower (Electric)
    or
    Horsepower (HP) [I think this one involves real horses] :D

    Hello Jaeger,

    all I was taught was that 1 H.P. = 746 watts. How the different H.P.'s came about and how they vary I don't know. You forgot RAC H.P., by the way :-),
