You could ask Dave Palmer, KB5WIA if he noted that spec., when he rebuilt his Yaesu motor last year (March 2012) http://kb5wia.blogspot.com/2012/03/yaesu-g5500-rotator-motor-repair.html

Anybody know what the rpm of the AC motors are. I know from the Yaesu specs that after all of the gear reduction they list EL as 67 seconds for EL and 58 Seconds for AZ.
I would like to experiment with an AZ and EL system but like to see what RPM the motor starts out with and how much torque to get the final results. They show Elevation at 101 FT-LBS and AZ at 44 FT-lbs.
I have looked around to see if somewhere the specs are available for the motor but have had no luck. I have seen quite a few pictures of rebuilds of that rotor with part number and have a manual that shows parts.
