Oh, I didn't measure the rotation speed of the motor during my rebuild, unfortunately. In all the research I did prior to the rebuild (=scrambling to find an equivalent motor) I didn't see any published specs on the unit either. I'd think Domenico's calculations would probably be the closest, since it is a simple 2-pole AC motor.

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.
