Electric motors involve rotating coils of wire which are driven by the magnetic force exerted by a magnetic field on an electric current. They transform electrical energy into mechanical energy and they can be classified into direct current or DC and alternating current or AC motors. DC or AC is a very common term which refers to how the electrical current is transferred through and from the motor. Both types of motors have different utilities and uses.
This course is designed to help students to understand the constructional features and operation of motors and its interfacing to microcontrollers including linear electro-pneumatic actuators and smas (muscle wire) and solenoids.
After completing this course, students will have expert knowledge on the construction, characteristics, operation and application on various types of motors.
