Unit 8 - Vocab D

a computer program that loads an operating system or some other system software for the computer after completion of the power-on self-tests. it is the loader for the operating system itself.

• capacitor
• amp/ampere
• hard cutoff
• bootloader

feature of an ESC firmware basically synchronizes the output of the ESC and the throttle signal thereby preventing synchronization issues at high RPM.

• channel
• amp hour (Ah)
• back electromotive force (back-EMF)
• OneShot

refers to the concept of reducing the motor RPM to hold the voltage at a set voltage.

• circuit
• 3-phase
• binary code
• soft cutoff

feature isolates the signal from the transmitter’s throttle channel to the ESC. Doing this can dramatically reduce the level of radio interference that can be created by very high current.

• current
• burst current
• complementary PWM
• OPTO (Optoisolator)

reduces the battery voltage to a level that can be safely used by the flight controller. The obvious disadvantage to OPTO ESCs is that you need to add an additional component to the power system.

• electron
• calibration
• Constant Discharge Rate
• UBEC (Universal Battery Eliminator Circuit)

is an electronic circuit designed to deliver electrical power to other circuitry without the need for multiple batteries.

• ESCs (Electronic Speed Controllers)
• duty cycle
• Encoding
• BEC (Battery Eliminator Circuit)

a firmware option for ESCs with a standalone GUI interface

• LED (light- emitting-diode)
• failsafe
• exponential function
• BLHeli

refers to having the property of conducting something (especially heat or electricity).

• LiPo (lithium polymer
• mAh (milliampere hours)
• FETs (field effect transistors)
• conductive

refers to updating or replacing firmware in a system.

• ohm
• ms (milliseconds)
• firmware
• flashed

a dynamo or similar machine for converting mechanical energy into electricity.

• Ohm’s Law
• PDB (power distribution board)
• flywheel
• generator
