October 10 – Day 5: Field Oriented Control Overview & Sine Wave Excitation II
Continuing Education Center 
10/10/2014  Post a comment
This discussion continues building upon our FOC motor control introduction. We will look more closely at the basic mathematical transforms, space vector PWM modulation, position sensing, and position estimator techniques. We will introduce key mathematical concepts of FOC control and explore their implementation.
October 9 – Day 4: Field Oriented Control Overview & Sine Wave Excitation I
Continuing Education Center 
10/9/2014  Post a comment
This discussion expands our scope to the hot new area of field oriented motor control (FOC) of Permanent Magnet Synchronous Machines (PMSM) motors. These sinusoidally-driven motors provide low torque ripple and highly efficient operation. This discussion will provide an introduction and comparison of FOC drive with respect to standard BLDC drive.
October 8 – Day 3: The Brushless DC Motor: Position Sensing, Power Sensing & Control
Continuing Education Center 
10/8/2014  Post a comment
This discussion is a continuation of day two’s discussion. We continue to discuss energy input devices and topologies, but now with a focus on torque, velocity, and position control. We will discuss various power sensing, phase sensing, and current sensing topologies. We will also touch upon sensorless design techniques.
October 7 – Day 2: The Brushless DC Motor: Trapezoidal PWM Control
Continuing Education Center 
10/7/2014  Post a comment
This discussion addresses energy input circuits and components starting with the Field Effect Transistor, and working our way up to the six-FET drive circuit. We will discuss differences between energy input circuit topologies for brushless vs. brush motor topologies.
October 6 – Day 1: The Brushless DC Motor: An Overview
Continuing Education Center 
10/6/2014  Post a comment
This discussion describes the brushless DC motor as distinct from the brush-style DC motor, stepper motors, and other motor types. We’ll look at the anatomy of the brushless DC motor and review manufacturer motor specifications, speed/torque curves, motor sizing, and power ratings. We will discuss motor commutation without brushes.
August 16 - Day 5: Brush DC Motors - Making Them Do Cool Things
Continuing Education Center 
8/16/2013  217 comments
This discussion introduces feedback to our controller discussion. We will discuss position encoding and quadrature encoders, as well as constant velocity control, P and PI control loops, and microcontroller systems.
August 15 - Day 4: Brush DC Motors - Making Them Stop
Continuing Education Center 
8/15/2013  198 comments
This discussion moves our focus from energy input to braking, friction, torque control, and back EMF effects. During this discussion we will discuss what happens as we decelerate. We will discuss regenerative braking.
August 14 - Day 3: Brush DC Motors - Keeping Them Cool
Continuing Education Center 
8/14/2013  242 comments
This discussion is a continuation of Day 2’s discussion. We continue to discuss energy input devices and topologies, but now with a focus on controlling device heating, heat sinking, and EMI reduction techniques.
August 13 - Day 2: Brush DC Motors - Making Them Go
Continuing Education Center 
8/13/2013  234 comments
This discussion address energy input circuits and components. Starting with the Field Effect Transistor, and working our way up to the H-bridge, we will discuss various energy input circuit topologies.
August 12 - Day 1: The Brush DC Motor – an Overview
Continuing Education Center 
8/12/2013  295 comments
This discussion describes the brush DC motor, and how it differs from a brushless DC motor, a stepper motor, and other motor types. In this discussion, we’ll break down the brush DC motor, showing exactly how it operates. We will review manufacturer motor specifications, speed/torque curves, motor sizing, and power ratings. We will discuss motor commutation using brushes.
