An automotive engine develops maximum torque at a speed of 1000 rpm At this speed, the power developed by the engine is 25 kW. The engine is equipped with a single plate clutch having two pairs of friction surfaces. The mean diameter of the friction disk is 190 mm and the coefficient of friction is 0.35. Six springs, with a spring index of 6, provide the necessary axial force. The springs are made of patented and cold-drawn steel wires of...

A 6-pole, 50 Hz, 3-phase induction motor running on full load develops a useful torque of 160 Nm when the rotor emf makes 120 complete cycles per minute. The windage and friction loss is 1005.30 Watt. It is assumed; the core loss is lumped together with the windage and friction loss. The total stator loss is given to be 800 Watt. Compute: a) Shaft power output, b) The copper loss in the rotor winding,c) The input power to the motor, and d) The...

Please Show Work 1. A hydraulic motor provides torque to a load through a shaft turning at 632 rev/min. The motor has 29 gal/min of fluid going through it, and the pressure at the motor inlet is 2,191 psi. What torque (in ft-lb) is the motor providing? (Assume 100 % efficiency). 2. Fluid is flowing at a velocity of 2 ft/s in a 0.6 in. ID pipe. The pipe transitions to an ID of 3 in. What is the fluid...

Immediate!! An induction motor has the following parameters. Determine the maximum transient torque that can occur when the 100 hp motor is plug reversed (sudden reversal of the excitation phase rotation). Assume the machine is running in the steady state with rated load prior to the plugging and that the load torque is constant over the interval of interest. Also assume that all three phases disconnect and connect simultaneously and that the time between opening and closing can be varied....

Consider that you need to determine how to power a load that will double after 3 years of the initial operation. You have the option of buying enough DG units to power the initial load and the load increase in 3 years for $ 2M or you can buy enough for the initial load by $1M and buy the rest of the DG units in 3years. Consider that the annual inflation rate is 3%. You are financing your capital investment...

: A dc motor develops 55 N-m torque at a speed of 600 rad/s when 12 volts are applied. It stalls out at this voltage with 100 N- m of torque. If the inertia and damping of the armature are 7 kg-m2 and 3 N-m -s/rad, respectively, find the transfer function, G(s) = θL(s)/Ea(s), of this motor if it drives an inertia load of 105 kg-m2 through a gear train, as shown in the figure 11.

A motor apply power 10-hp split-phase motor speed at 1700 rpm is used to drive a rotary pump, which operates 24 hours per day. An engineer has specified a 7-in small sheave, an 10-in large sheave, and three C112 belts. The service factor of 1.2 was augmented by 0.1 because of the continuous-duty requirement. Analyze the drive and estimate the belt life in passes and hours.
