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 |
