Motors

Motors research:

For a deeper insight on how motors work, and when you should use each type:

1. Motors for Makers (Matthew Scarpino)

Contents:

This subcarpet contains information about ESCs (Electronic Speed Controllers), and motors themselves.

I still don't know the function for the **Robomaster Assistant**. But I included it. I hope it has controllers. As of the writing of this document, V.1.9 is the lattest release. 

Notation:

Abbreviation	Meaning
SC / ESC	Speed Controller
BLDC	Brushless DC
SWDC	Series-Wound DC
SHWDC	Shunt-Wound DC
PMDC	Permanent Magnet DC

Take into account:

For motors

For ESC

If you are researching an ESC, add this table to the description:

State/Parameter	Description	Is Present (Y/N)	Command
Auto-cutoff	Sets the voltage at wich the ESC reduces power due to a low-voltage state.
Brake	Sets the motor to braking position. The throttle is the minimum to stop rotation (But doesn't stops a load).
Coast	Let's the motor rotate until stopped by inertia.
Timing	Identifies how quickly pulses are deliverd to the BLDC
Reverse	Run in reverse direction.
Reverse delay	The amount of time defore each reverse in direction
Current limiter	Sets the masimum amount of current that can be deliered to the motor
Switching freq	Sets the PMW frequency of the motor control signal
Starting acc	Dines how quickly the motor should be accelerated during starp-up
Battery type	Sets the type of battery that supplies power to the ESC

Tips:

• Never run a motor to it's full pottential constantly.
• For a more responsive throttle, increase Switching freq.
• Motors consume more current at start-up, don't force it with a load.
