First of all, thank you for the great development!
I have an overheating issue with my setup:
b_g431_esc with SunnySky X2212-13 (980KV) driven by 3S (around 12V) battery in open-loop mode
I have reduced the voltage limitation on the driver and motor as mentioned [1], [2]. My code:
#include <SimpleFOC.h>
// BLDCMotor( pole_pairs )
BLDCMotor motor = BLDCMotor(7);
BLDCDriver6PWM driver = BLDCDriver6PWM(A_PHASE_UH,
A_PHASE_UL,
A_PHASE_VH,
A_PHASE_VL,
A_PHASE_WH,
A_PHASE_WL);
// the setup routine runs once when you press reset:
void setup() {
// driver config
// power supply voltage [V]
driver.voltage_power_supply = 12.0;
driver.voltage_limit = 2.4; // limit the source voltage because it heats up
driver.init();
//Link the motor and the driver
motor.linkDriver(&driver);
// limiting motor movements
motor.voltage_limit = 1.2; //half of 'driver.voltage_limit'
//
motor.velocity_limit = 15; // [rad/s]
// open loop control config
motor.controller = MotionControlType::velocity_openloop;
// init motor hardware
motor.init();
delay(3000);
}
//The loop routine runs over and over again forever:
void loop() {
motor.move(3);
}
Are there any other limitations in the configuration that might help to reduce temperature in open loop velocity mode? Or does low-speed control require sensors?
Thank you in advance and any help is appreciated!
