Power Supply to ODrive with Two D6374 Motors

1

I am looking to connect two D6374 Motors to the ODrive V3.6 56V controller. I was wondering if anybody had any suggestions for a good power supply for this setup. I am looking for torque control of the motors and a budget of $100 or less but will exceed the budget if the power supply is worth it. Let me know if anybody has any suggestions!

Hi

How fast do you need them to turn?

Cheers

More importantly than fast, how much power do you want at the motor side?

I have the same interest and the same issue.
I have the Odrive v3.6 56V connected with one odrive d6364motor and amt102-v encoder.
the power supply that i’m using at the moment is 30V and 5A.
using these parts, i can calibrate correctly the motor using the command:
odrv0.axis0.requested_state = AXIS_STATE_FULL_CALIBRATION_SEQUENCE
i can hear the beep motor sound and it turns one round in both directions.
after that, i’m trying to run 50 turns with these commands:

 odrv0.axis0.requested_state = AXIS_STATE_CLOSED_LOOP_CONTROL
odrv0.axis0.controller.input_pos = 50.0

but it only rotates one time and fail.
the dump.errors return me that:

system: Error(s):
  LegacyODriveError.DC_BUS_OVER_REGEN_CURRENT
axis0
  axis: Error(s):
    AxisError.MOTOR_FAILED
  motor: Error(s):
    MotorError.SYSTEM_LEVEL
  DRV fault: none
  sensorless_estimator: no error
  encoder: no error
  controller: no error
axis1
  axis: Error(s):
    AxisError.MOTOR_FAILED
  motor: Error(s):
    MotorError.SYSTEM_LEVEL
  DRV fault: none
  sensorless_estimator: no error
  encoder: no error
  controller: no error

I suppose that i’m having problems with the power supply. that’s why i’m asking **which kind of power supply will work with two d6374? i want to have high speed to create adiabatic movement (3000-5700) and high torque to move 10kg **
