A synchronous machine always runs at synchronous speed. With loading, it would only slip through a small angle (not speed) and if the load torque is outside specification, it'd lose synchronisation and stall, but never run at a speed different from the synchronous speed i.e. 120f/p, hence the name. The speed is accurate as long as the frequency of the AC supply is equally so.
You're talking asynchronous or induction machine.

Volts and amps are at right angles, so then the motor will lock, it has to slip to get the squirrel cage effect to keep running, slip / lag is essential.
That is for AC motors, synchronous or not, I will have to check, that is slightly off this thread topic.

First, I learned all this 40 years back, and I do not have the time and inclination to learn about motor design all over again just to argue or discuss with you.
Second, I think this is going off topic, and is of no help to the person who started this thread with his problem.
The phase angle between volts and amps changes with capacitive and inductive loads, it is a well known and treated topic in electrical engineering texts.
I am a mechanical engineer, who is into plastic injection moulding, for me learning motor design is useless, if my motor fails, it goes for replacement or repair, if three phase.
Single phase motors like fans and air conditioners, replace capacitor if needed. Otherwise, off to repair shop.
Single phase squirrel cage motor running slow? Strip, lube, assemble, and if needed, send for service / repair.
Series motor on a drill or blower? Check brushes , then armature after checking switch and supply.
I do not think any average end user designs a single motor for his use, think of all the parts needed.
Check this out, really large range of motors, they are having a large production volume:https://www.mabuchi-motor.com/product/
No ties, just a heads-up.
