Pintodeluxe is on to it… the number of wraps and size of the electric coils in the motor determine how much current can run through it. Motors with more copper wrapped into the coils can handle more amperage. More amperage leads to more torque applied to the shaft. More torque at the shaft means it can resist more torque that you apply to the end of the tool. Sounds like the dremel has a beefier motor, while the no-name comes up short. Also probably accounts for the difference in sound… more power is usually noisier in motors of that design.
