If the mechanical load occurs on the shaft of synchronous motor than at that time torque angle decreases the back emf for a few seconds of motor or not?

when mechanical load is increased, motor needs to generate more power. so motor needs to increase the component of current in phase with voltage (u need to see this in phasor diagram). so to do this, load angle increses but this has got nothing to do with the magnitude of E. so magnitude remains the same.

when load on SM increases the torque angle increases to meet the demand but it has no effect on E
magnetic lines b/w stator and rotor pole get streched.
