2.3 Methods of Power Transfer - Direct Coupling/using Belt Drive, Gears, Pulleys
A horizontal conveyer belt moving at a uniform speed of 2.2 m/s transports material at the rate of 200 tones/hour. Belt is 100 m long and driven by a motor at 1500 rpm. (i) Determine load inertia referred to motor shaft. (ii) Calculate torque that motor should develop to accelerate the belt from standstill to fill speed in 8 second. Moment of inertia of motor is 0.1 kg-m².
