### Description:

"Provided a good overview that gave a general understanding and appreciation of the topic. It is a good starting point for study." ~Laura Howard

This course gives you a broad perspective of DC motors, AC motors (single and three-phase), and Variable Speed Drives (for AC Induction Motors and DC Motors). Industrial applications of Variable Speed Drives for constant torque, constant horsepower, and variable torque/variable horsepower are included. Also covered are Motor Starter Circuits and Reduced Voltage Starting techniques. Stepper Motors and Servo Motors are discussed along with their advantages and applications.

### You will be able to:

• Define motor torque and horsepower
• Calculate volts per hertz ratio as related to Variable Frequency Drives
• Specify, select, and implement motors for variable torque and horsepower
• Recognize how variable frequency AC drives operate
• Determine the need for variable speed drives in industrial processes
• Interpret motor performance curves
• Differentiate between slip and synchronous speed induction motors
• Apply procedures to reverse direction of a three-phase motor
• Identify the advantages of brushless DC motors
• Discuss stepper and servo motor systems for industrial applications
• Explain the differences in various motion control feedback devices
