1 Victor 2 Window Motors

[Ether]

if the two motors are linked mechanically, feeding both from the same victor may prove to be too frustrating in the end. The production standards are not tight enough to allow any two motors to run at identical speeds with the same drive. Although linked together, the difference may just damage one or more motors

If the motors are linked mechanically, then they will run at the same speed. But due to manufacturing tolerances, they will not share the load (torque) exactly equally. As long as you design with this in mind and allow enough margin so that the more-heavily-loaded motor is not overstressed, there should be no motor damage.
