I am trying to get a LG brushless washing machine motor operated by Odrive PRO.
Similar as shown here: https://www.youtube.com/watch?v=g-o0L7QaY3k
The Hall sensor has only two signals, GND and +, so 4 wires
I am using a 240 W, 19V power supply.
The current setup fails:
In [1]: odrv0.config.dc_bus_overvoltage_trip_level = 24
…: odrv0.config.dc_max_positive_current = 20
…: odrv0.config.dc_max_negative_current = -0.01
…: odrv0.axis0.config.motor.motor_type = MotorType.HIGH_CURRENT
…: odrv0.axis0.config.motor.pole_pairs = 6
…: odrv0.axis0.config.motor.torque_constant = 1
…: odrv0.axis0.config.motor.calibration_current = 0.5
…: odrv0.axis0.config.motor.resistance_calib_max_voltage = 9
…: odrv0.axis0.config.calibration_lockin.current = 10
…: odrv0.axis0.config.motor.current_soft_max = 2
…: odrv0.axis0.config.motor.current_hard_max = 5
…: odrv0.axis0.requested_state = AxisState.MOTOR_CALIBRATION
In [2]: dump_errors(odrv0)
axis0
active_errors: no error
disarm_reason: Error(s):
ODriveError.DC_BUS_OVER_REGEN_CURRENT
procedure_result: ProcedureResult.DISARMED
last_drv_fault: none
internal issues: none
Any idea is welcome that help to get the motor running at low RPM (<50). Thank you!
