Design and explain a series of tests in order to characterise an electric motor used in a screwdriver. The tests should measure: 1- The no load speed of the motor (rad/s) 2- The stall torque of the motor (Nm) 3- Motor coil resistance (internal resistance in ohms) Note: Please carefully explain how you would carry out a series of tests to determine the data listed above for an electric screwdrivers DC motor.

1) Explain how practical electric motors are able to produce
torque always in the same direction through 360 degrees of rotation
of the motor. (See page 482 in your text, but note that there is an
error in the diagram in the Application: Electric Motors box. The
direction of rotation is incorrect. See if you can figure out
why.)
2) If you needed to get more torque from the winch on your
pickup and you had an extra 12 V...
