Direct drive The simplest drive system is a direct drive, Figure 3. Because there are no me - chanical linkages involved the load pa - rameters are directly transmitted to the motor. The speed of the motor is the same as that of the load, so the load fric-tion is the friction the motor must over-come, and load inertia is what the motor "sees."
