In the system shown in Figure 1 , the gear ratio au =0.5,J_(m)=10kg-m^(2), and J_(L)=2.5kg-m^(2). Damping and friction can be neglected and the load torque is assumed to be constant 100 N.m). For the load-speed profile shown in the same figure, [6]
2.1. Draw the torque profile of the motor
2.2. Calculate the effective value of the electromagnetic torque required from the motor
2.3. Calculate the approximated power rating of the motor. Use the speed in region (2) as rated speed.
