    var fa, b, fb, c, y = [];

        while(cont != 100){
        fa = f.length;
        fa = fa - 1;
        b  = f.charAt(fa);
        fb = f.slice(0,fa);
        c  = b.concat(fb);
        y = y +"<br>"+ c

Use the setInterval function.

function whileComIntervalo ()
{
    while (cont != 100)
    { /* Resto do código */ }
}

function rotateText(id,dt)
{ /* Declaração de variáveis */
    setInterval(whileComIntervalo, 1000);
}

setInterval receives a function and a time value in milliseconds (1000 ms = 1 second) as a parameter
