ARM based 32bit ESC. ESC32
These ESC will increase the handling and stability of any multirotor system greatly.
some soldering may be required, see plug and play options below for solder-free. Free power harness with purchase of three or more
All units flashed with lastest firmware. and settings options below for Pnp.
- All N-FET design
- 2s-5S up to 30Amps
- Option to power logic side via UART or PWM IN +5v
- compatible with ESC32 opec source firmware
- 4KHz to 64KHz PWM out
- Current sensing / limiting with real shunt resistor
- Virtual current limiter
works Great with MWC and naza FC, make sure you have the correct settings. comes with firmware flashed.
For multiwii change #define MINCOMMAND 1000 to 900 for the esc to initiate.
Vb=power from battery
V5=power needs to come from the "servo lead"
by selecting 5V you can power up the logic side separately when
flashing firmware/settings, without o power up the motors.
When using the 5V option to you must always DISCONNECT MAIN INPUT FIRST
before disconnecting the 5V power from the logic side – disconnecting
5V while the main is still powered can damage the ESC.
PWM_MIN_PERIOD 2200 The minimum period in microseconds that the ESC will consider an input PWM waveform to be valid. Default value represents approx 450Hz. For MultiWii and ArduCopter APM this value needs to be changed to 2000! PWM_MIN_VALUE 750 The minimum input PWM pulse length in microseconds which the ESC will consider to be valid.For DJI Naza this value has to be 900!
Most standard ESCs are not designed for multirotor applications. Most ESCs are build and configured with an airplane application in mind, they are programmed to increase and decrease the throttle command towards the motor in a gentle way for obvious reasons. A motor fast accelerating and decelerating in an airplane or helicopter would either break the gears or put great stress on the prop and airframe. A multirotor is different. We would rather have a total linear curve and able to change the motor speed, and thus the thrust, as fast as possible to achieve a perfectly stable platform.
While the current ESCs used in most multrotor applications work considerably well, there is a lot of room for improvement. Using the same ESC but loading it with dedicated optimized firmware will increase the handling and stability of your multirotor greatly.
Most flight controllers will benefit from ESCs that can operate at PWM frequencies of at least 400hz and are stripped from a controlled throttle curve.
Thats where the ESC32 comes in, a superior 32 bits ESC with a lot of interfaces and room for future enhancements.
ESC32 -- OpenPilot change the motor output setting to 900 in the OP GCS
