DC MOTOR THEORY
DC motors are hugely used to drive several equipment. The torque and speed generates in a DC motor depends on a variety of factors.
- Using the right-hand rule for motors and DETERMINE the direction of the magnetic field, force on a conductor or direction of current flow.
- STATE the function of torque in a direct current motor and how it is established.
- DESCRIBE how CEMF (Counterelectromotive Force) is established in a DC motor.
- DESCRIBE the relationship among field current and magnetic field size within a DC motor.
- STATE the function of the CEMF which is developed in a DC motor.
- DESCRIBE how the speed of a DC motor is adjusted.
- DESCRIBES the relationship among armature current and torque generates in a DC motor.
