I have my synchronous motor with the rotor set-up.  How am I able to tell if
my motor is running at the correct speed and that the rotational weight of
my rotor is not slowing the motor down.  Any easy way to determine this?  I
don't have access to any type of motor tachometer whether it be a physical
connect one or ones that use a light beam and a piece of tape on the shaft.

Thanks
