Assume that a motor has known friction and win dage losses described by the equation TFW = bω. Sketch the T -ω characteristic of the motor if the load torque, TL, is constant, and the TL-ω characteristic if the motor torque is constant. Assume that TFW at full speed is equal to 30 percent of the load torque.
The summing amplifier in Figure P14.15 has an op-amp with open-loop parameters: AOL = 2 × 103, Ri = ∞, and Ro = 0. Determine the actual output voltage as a function of vI1 and vI2. What is the percent error from the ideal value?
An auto transformer is used to reduce the starting current and to give full load torque at starting .Neglecting no load current , determine : (a) Voltage applied at starting , (b) Full load line current (c) Current drawn by the motor at starting..
The transmitting fiber has a core diameter of 80µm and the receiving fiber has a core diameter of 110µm. The transmitting fiber has n1=1.46 n2=1.40 and the receiving fiber has n1=1.48 and n2=1.46. Will this joint meet the loss restrictions
