My guess is that the motor is running on 2 poles only which may account for the higher speed. Also, when testing the mixer with bread dough, 2nd speed looses torque and is reduced to 1st speed rpm.
Yes, it has movable brushes and is set cc rotation (per manual). At the lowest rpm on speed 1, it starts at about 60 rpm. As I rotate clockwise slowly, the run rpm engages at 120 rpm. The further I turn it, the run rpm starts quicker but at the same 120 rpm.
It's still connected as 4 pole and the motor is not rewound. I replaced the original switch as it was shorting out and throwing sparks. I'm thinking maybe the wires are paired wrong at the switch.
Hello everyone,
I have an old Hobart A200 mixer that I've rebuilt and the problem is the agitator shaft is spinning twice the rated speed when the motor comes up to speed. It has a repulsive induction motor. Speed 1 starts at about the rated 60 rpm but spins at about 120 when at running speed...
