Chapter 1, Problem 1.23P

For the linear machine of Problem 1-22:

  1. When this machine is operating as a motor, calculate the speed of the bar for loads of O N to 30 N in 5 N steps. Plot the speed of the bar as a function of load.
  2. Assume that the motor is operation with a 30 N load, and calculate and plot the speed of the bar for magnetic flux densities of 0.3 T to 0.5 T in 0.05 T steps.
  3. Assume that the motor is running at no-load conditions with a flux density of 0.5 T. What is the speed of the bar? Now apply a 30 N load to the bar. What is the new speed of the bar? What flux density would be required to restore the loaded bar to the same speed that it had under no-load conditions?
