A DC motor is used to lift up a weight of 1000 kg as shown in Figure (2). The motor speed is 900 rpm. Determine the load torque seen by the motor. Assume that the acceleration of gravity is 9.81 m/s2 and the gear efficiency is 100 %. a = 1:10 d = 0.6 m, Winch drum Motor Jw = 3 kg m? Ja = 1 kg.m? Gear Box do = 0.2 kg.m Load 1000 kg Y (m/sec) A DC motor is used to lift up a weight of 1000 kg as shown in Figure (2). The motor speed is 900 rpm. Determine the load torque seen by the motor.
