Study Notes
Primary Function of an Electric Motor
- Converts electrical energy into mechanical energy to perform work or drive machinery.
Powering Electric Motors
- Can be powered by alternating current (AC), direct current (DC), or universal power supplies.
- Various voltage levels and frequencies can be applied depending on the motor design and application.
Distinction Between Electric Generators and Electric Motors
- Electric motors consume electrical energy to create motion, while electric generators produce electrical energy by converting mechanical energy from a rotating element.
- Motors operate on the principle of electromagnetism, whereas generators rely on electromagnetic induction.
Classification of Electric Motors
- Classified into AC motors, DC motors, and universal motors based on their power supply type.
- Further categorized into synchronous, induction, and stepper motors for AC and brushed or brushless for DC.
Largest Electric Motors Applications
- Typically powers large industrial machinery, ships, and compressors in heavy-duty applications.
- Commonly found in power plants, hydroelectric facilities, and large manufacturing operations.
