Motor torque curves

[chuckd83]

I was given a motor data sheet from the 90's that includes speed vs. current, power factor, average torque @ 100% and 90% V, load torque, and oscillating torque @ 100% and 90% V.

What are the oscillating torque curves? I've never heard of that.

Is this a synchronous motor?
