Wiring an AC motor (4 wires)?

I am trying to wire up a salvaged AC motor for a lab project. It is a single phase 1/3 HP 115 volt 6.9 amp motor with four wires coming out of it and no schematic... It would seem that the wires are somehow paired as they come out of the motor, T0 and T5 are together, and T1 and T8 are together. The motor has a set of brushes so I assume it is a universal motor. Before I go hooking it up all willy-nilly like, I was wondering if anyone could shed a little insight on this problem. Also, I assume that this motor is reversible, so if anyone could give me a little help on that I would be grateful.

Answer:

ya motor might want to o.k. be a stepping motor run by technique of a chip that aspects a pulsed provide around the three wires which it reverses by technique of reversing the pulses reminiscent of a lightchaser in case you go with to flow into this further attempt googling this chip- SAA 1027
T5 and T8 would indicate, to me, that it is a split phase type motor, t5/t8 being the start winding, which you run in parallel with the run winding. Which way depends on the direction you want the motor to turn. If it has brushes, it could be a repulsive-induction start (where the brushes short the armature to start, and open to run, you adjust the position of the brushes to change rotation), a universal where the armature and field windings are series, or a straight DC PM motor (T0/T1 may be a thermal cutout).
