What do you need to check for when buying a used DC motor with speed control
 

I am buying a used DC motor with speed control. It's rusted and looks
like it was heavily used. What should I check for to make sure it works
properly?

Speed control is
Speed-a-matic PN2400-8000
(1/4 to 1HP for 115VAC and 1/2 to 2 HP for 230 VAC )
Input 14.5 A max Outpt 10 A max

Motor Baldor# CD3475,
3/4 HP,
volts 90A/100/50F,
amp 7.8/.6/1.2F,
RPM 1750

Looks like your getting a shunt wound motor because of the field rating on
the motor. Not a minus, at all. Rust might not be a problem if the motor
is free and bearings feel smooth and tight. You might need a heat sink for
the controller (I'm not familiar with that one). IF the price is
right........ As long as there are no apparent "smoke holes" on the
controller, you really won't know until you hook it up and run it.

Don't ever get a motor that's painted blue. Something in the blue pigment
interferes with the magnetic flux density, measured in oersteds (OE),
directly corelating to the shade of blue. Although the force due to the
magnetic field may be different in different hue values because magnetic
fields transform into electric fields under Lorentz transformations unless
the motor is alligned with magnetic north, not true north. Initial rotation
will depend on the position and phase of the moon and obviously which
hemisphere the motor will opperate in.

Keep it up, Tom and we're gonna put you on permanent troll patroll.

You know, I didn't know that.

You learn something every day!
