No load speed is the speed that the motor run when it has no load, i.e., the motor is separated from the engine, that speed is than greater than the rated speed, because the rated speed is the speed whwn the motor are linked to the load and it is the full load.
synchronous motor is a constant speed motor because it will only run at a synchronous speed or not at all.the speed can be changed by changiing the frequency only ns=120f/p
Dc shunt motor is constant speed motor.Its speed is constant with armature current.This shunt motor is used in paper mills and drilling machines
No, unless it is a three phase motor and you reverse only two of the phases.
by reversing the connection of the two windings

Reverse the polarity of armature windings of the motor.
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.

Motor speed is a term we often use to speak to the rotational speed of a motor. And often we talk about the speed of rotation in revolutions per minute, or RPM.
