"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

  • DC Motors Theory and Construction: Series | Shunt | Compound
  • DC Motor Torque and Horsepower Control: Field Control | Armature Control
  • Single-Phase AC Motor Theory and Construction: Squirrel Cage | Induction Rotor | Split Phase and Capacitive Start
  • Three-Phase AC Motor Theory and Construction: Squirrel Cage | Induction Rotor | Wye Field Winding | Delta Field Winding | Self Starting
  • Motor Specifications: NEMA Designs and Types | Torque vs. Speed Curves
  • Motor Control Circuits: 2-Wire Control | 3-Wire Control | Magnetic Motor Starters | Soft Start
  • Motor Applications: Constant Torque vs. Variable Horsepower | Constant Horsepower vs. Variable Torque | Variable Torque vs. Variable Horsepower
  • Solid State DC Drives: Constant Torque Control | Constant Horsepower Control
  • AC Drive Characteristics: Volts per Hertz | Variable Voltage Input (VVI) | Pulse Width Modulated (PWM) | Flux Vector Drives (FVD) | Typical Control Applications
  • Servo Systems: Brushless DC Motors | Position Loop Systems | Positioners (Encoders)
  • Stepper Motor Systems: Theory of Operation | Advantages/Disadvantages | Application Selection
