A gear box has the input power 10kw at 2400 rev/min. The gear ratio is a reduction of 2 to 1. The efficiency is 98%. What is the holding torque required?
Use Newtons Law to derive equations of motion for the system. This should be converted into transfer functions for input into MATLAB/SIMULINK. The system consists of a motorised trolley on a see-saw (see attached figure). The trolley motor is to be controlled and eventually the trolley must balance the beam. A potentiometer s
A uniform rigid disk of radius r and mass m rolls without slipping on a smooth horizontal surface. A constant force of magnitude P is applied to the rim of the disk at distance r above the horizontal surface and in the direction of motion. r,m,P are known. what is the angular acceleration in terms of known quantities, and wha
Find the starting torque, the maximum torque, and the speed at maximum torque for a 3 phase, 50 Hz, 6 pole wound rotor induction machine.
A 3 phase, 50 Hz, 6 pole wound rotor induction machine has the following per phase parameters: Rs = Negligible Ls = 0.003 H Rr = 0.3 Ohm Lr = 0.002 H Lm = 0.1 H Rc = Infinity Ns/Nr = 1.2 The voltage applied to each phase is 240 Vrms. Find: the starting torque, the maximum torque, and the speed at max
