PWM controlled Motors will have a lower torque compared to a regular dc power supply, because the power supply is "chopped" into pulses...but you won't detect the chopping on your regular voltmeter because it won't pick up the fluctuation. It is basic physics, and you can test it.
Torque in a DC motor depends on the current, and current is not chopped into pulses. The inductance of the motor winding smoothes it very effectively.
If the PWM is 100%, it is the same as direct connection to the supply of course
Different decay modes with PWM (fast, slow, synchronous rectification) will map PWM duty cycle into current
very differently though (and often in a load-dependent, non-linear way).

I often wonder about the mentality of some one who brings back to life a thread that is years old. This time only two but years nevertheless. And does so to include such information that is hardly relevant to what looks like a solved problem.
