A brushless dc motor and a suitable drive unit are to be chosen for a continuous drive application. The load has a moment of inertia 0.016 kg.m², and faces a constant resisting torque of 35.0 N.m (excluding the inertia torque) throughout the operation. The application involves accelerating the load from rest to a speed of 250 rpm in 0.2 s, maintaining it at this period for extended periods, and then decelerating to rest in 0.2 s. A gear unit with step down gear ratio 4 is to be used with the motor. Estimate a suitable value for the moment of inertia of the motor rotor, for a fairly optimal design. Gear efficiency is known to be 0.8. Determine a value for continuous torque and a corresponding value for operating speed on which a selection of a motor and a drive unit can be made.
