TERMINAL OBJECTIVE 1.0 Given the type and application of a DC motor, DESCRIBE the operating characteristics of that motor to include methods of speed variation, advantages of each type, and torque vs speed characteristics. ENABLING OBJECTIVES 1.1 Using the right-hand rule for motors, DETERMINE the direction of the magnetic field, direction of current flow, or force on a conductor. 1.2 STATE the function of torque in a direct current motor and how it is developed. 1.3 DESCRIBE how Counterelectromotive Force (CEMF) is developed in a DC motor. 1.4 DESCRIBE the relationship between field current and magnetic field size in a DC motor. 1.5 STATE the function of the CEMF that is developed in a DC motor. 1.6 DESCRIBE how the speed of a DC motor is adjusted. 1.7 DESCRIBE the relationship between armature current and torque produced in a DC motor. 1.8 DESCRIBE the differences in construction between a shunt-wound and a series-wound DC motor with respect to the relationship between the field and the armature windings. 1.9 DESCRIBE the construction of a compounded DC motor. 1.10 DESCRIBE the torque-vs-speed characteristics for a shunt-wound and a series-wound DC motor. 1.11 EXPLAIN why starting resistors are necessary for large DC motors. 1.12 LIST the four nameplate ratings for a DC motor.
