I think the two speeds quoted are for parrallel connection and series connection. That is armature in series with the field or in parallel.

Series connection has has good starting torque, and will keep on running faster and faster if on no load, possibly (even probably), fast enough to destroy itself. This is probaly what is used for spin cycle.

Parallel also has good starting, and tends to run to a constant speed, load or no load. The danger is that a field that is suitable for series operation will be too low an inductance for parallel.

Why not series connect it then wire the whole motor in series with a 500w halogen light bulb on a 5A fuse. Let it run up but be prepared to turn off if speed seems excessive.

If that works possibly try parallel motor configuration (with lamp).

The only way to know if a motor is working perfectly is to compare it to an identical one in your test rig.

One of those 'power measuring' adaptors is useful. It will tell you the amps and the watts being taken precisely.
