| BLDC | Brushless Direct Current |
| PWM | Pulse Width Modulation |
| Dead time | Buffer time between enabling transistors connected
to different voltages to avoid short circuiting the two voltage
levels |
| EMI | Electromagnetic Interference |
| Duty cycle | Used to describe the duration of the on-period of a
pulse width modulated signal |
| Hall effect sensor | Magnetic sensor commonly used for indicating the
angular position of the rotor in a brushless DC motor in order to
correctly apply current to the motor coils |
| Commutation | The act of applying current to the correct coils of
an electrical motor in order to make it turn |
| Steady state | The condition of a dynamic system when its states
(like speed, current, etc.) have stabilized |
| Open-loop control | Term used about a control scheme where information
about the system state or states that is to be controlled is not fed
back to the controller to create a closed control loop that adjusts
the controller output automatically based on the feedback |
| PCB | Printed Circuit Board |
| I/O | Input/Output. Used as collective term for input and
output signals to/from the device. |
| Shoot-through | Term commonly used about short circuiting a
transistor between supply voltage and ground, potentially damaging
the transistor |
