Unformatted text preview: EE 4002: Project #1 Elevator DC Motor By Carranza J. Guidry III 10/18/04 1.) Calculate the power of the motor and select (using Web Site of producer or vendor on internet, e.g. e-motorsonline.com ) the appropriate separately excited DC motor for driving the elevator. To determine the ratings of the motor use the following criteria and data: Calculation: X = 97 Mcab = 797 M 2 = 399 Mctw = M 1 = 199 Vup = 1m/s M 2 = 399 (Jp + Jg) = 9.7 kg*m^2 B = 9.7 (N*m)/ (rad/s) Ra = .103 ohms La = 9.7 mH Radius = .2m Rf = 110 ohms v = 1.5 m/s (steady state) Jm = .97 kg*m^2 W L = 2VL/R = 15 rad/s T L = R*G*(M2 – M1) + BW L T L = .2 * 9.8 (399 – 199) + 9.7*15 T L = 537.5 Nm T L(m) = T L /10 T L(m) = 537.5 /10 T L(m) = 53.8 Nm Pm = T L(m) W L Pm = 53.8 * 15 Pm = 1.08 hp MOTOR CHOSEN : Product ID: DCM00028 Horsepower: ¾ hp RPM: 1725 Armature Volts: 115 Since there were no DC motors that match the calculated supply power and armature volts, I chose the closest available hp motor. 2.) Write the voltage and motion equations for the whole system and draw the block 2....
