modulation of a torque signal over a certain number of motor revolutions ?

In vehicle seat structures a variety of motor-gear combinations are used  Rack or spindle drive for the slide adjustment, spur wheel, worm gear or planetary gear - coupling the motor over sometimes long, flexible shafts to the seat structure.  Each configuration, in particular spur gears, usually produces a modulation of the torque signal over a certain number of DC Motor revolutions.

Please explain the last sentence.

Pretty bad writing.

Each configuration  . . .  usually produces a modulation of the torque signal over a certain number of DC Motor revolutions.

Modulation is usually intentional, so there shouldn't be any usually.

I think they are trying to say that the torque required by the motor varies as the seat is moved.  Perhaps because of slight mechanical imperfections or misalignment in the gear train.

And it would be the imperfections, not the configuration, that cause the problem.
