- A 208 V, 50 Hz six pole, Y-connected, 27 hp design class B induction motor is tested in the laboratory, with the following results: No load: 208 V, 22.0 A, 1200 W, 50 Hz Locked rotor: 24.6 V, 64.5 A, 2200 W, 15 Hz DC test: 13.5 V, 64 A Find the equivalent circuit of this motor, and plot its torque-speed characteristic

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
