Industrial Engineering Permanent-magnet direct-current
Chapter , Problem 2.7.23(choose chapter or problem)
Industrial Engineering Permanent-magnet direct-current motors are used in a variety of industrial applications. For these motors to be effective, there must be a strong linear relationship between the current (in amps, A) supplied to the motor and the resulting torque (in newton-centimeters, N-cm) produced by the motor. A randomly selected motor is chosen from a production line and tested, with the following results. Direct-Current Motor Data at 12 VoltsCurrent(A)Torque(N-cm)7.3 9.411.9 2.85.6 5.614.2 4.97.9 7.0 Current(A)Torque(N-cm)8.5 8.67.9 4.314.5 9.512.7 8.310.6 4.7Based on the data in this table, is the chosen motor effective? Explain.
