The output torque of a motor is 69.2 lb-ft when it operates at 950 rpm. Calculate the losses in the machine and its efficiency if, under this condition, the power input is 10900 watts. Topic: DC MOTOR: Efficiency and Power Losses
A 12-pole, brushless, DC motor has a no-load speed of 5000rpm and a stall torque of 50 in-oz when operating at rated voltage of 60V. Testing shows that no-load speed and stall torque vary linearly with applied voltage. Also, with a constant applied voltage the speed decreases linearly as delivered torque increases. Calculate the following: Torque that the motor delivers at 2000 rpm when operated at rated voltage. T a) b) Fundamental frequency of the applied voltage waveform at this...
7. An 80 kW, 440 V, 800 rpm DC motor is operating at 600 rpm and developing 75% rated torque is controlled by 3-phase, six-pulse thyristor converter. If the back emf at rated speed is 410 V, determine the triggering angle of the converter. The input to the converter is 3-phase, 415 V, 50 Hz ac supply.
A motor is mounted on a relatively lightweight platform that is observed to vibrate excessively at an operating speed of 1,000 rpm producing a 150 N excitation force. The motor operating speed is 1 times the measured natural frequency of the combined motor/platform system. The lumped mass of the motor/platform system 5 kg. Otherwise the platform can be considered as a stiffness element.Design an undamped dynamic vibration absorber to add to the platform, tuned to the motor operating speed, noting...
