AC and DC Motors: AC Motor Maintenance CD-ROM

Duration: 4 hours (includes 1 test)

What Students Learn: This comprehensive Activ® interactive multimedia training program consists of four lessons that train participants to understand, maintain, and test AC and DC motors.

This lesson covers AC motor maintenance, including the three types of motor maintenance: preventive, periodic, and corrective maintenance. The lesson covers the various tools and instruments used to conduct motor maintenance and maintenance safety and recordkeeping. This lesson also explains why maintenance programs are important, characteristics of various types of maintenance, and maintenance tasks to be done during each type of maintenance.

After completing the lesson, the learner will be able to:

    •    Identify the characteristics of a motor maintenance program.
