Course Overview

Most of the electric appliances around us have an electric motor inside them. For example, they are used in Hoover Dam Hydroelectric plants, in wind farm power generation, watches, boats, jet engines, etc. In the petrochemical industry, motors are important because they provide rotational force or energy to the parts of equipment thus enabling effective performance of the equipment. This module covers the applications, components, working principles, types and routines checks of motors used in the process industry.

Target Audience
