hello,
i am trying to set up 3 identical motors onto the geobrick. they are rotary brushless. here are the motor electrical specs:
continous stall torque(Nm)- 2.3
continous stall current(A)- 2.6
rated torque(Nm)- 2.1
rated current(A)- 2.3
rated speed(rpm)- 4500
max speed(300V) (rpm)- 3900
max speed(560V) (rpm)- 7300
peak stall torque(Nm)- 6.9
Max. peak current(A)- 14
resistance line-line (Ohm)- 5.8
indcutance line-line(mH)- 13.5
voltage gradient(V)- 76
motor emf(V)- 610
force constant(Nm/A)- 0.9
# of poles- 8
setting up the geobrick seems straight however, i dont believe i have done the "Motor Info Step" in geobrick setup software accurately. at the moment, the geobrick is set up as:
pwm freq- 4.52kHz
phase freq- 9.03kHz
Servo freq- 2.26kHz
Bus voltage- 245-249V
rated current (Amp rms)- 2.6
peak current (Amp rms)- 9.8
time allowed at peak current- 2 secs
motor rated voltage(Vac rms)- 395
number of poles (optional)- 0
motor resistance phase-phase- 5.8 ohm
motor inductance phase-phase- 13.5mH
i am unsure if these values used are accurate with reference to the motor electrical specs.
in the feedback channel step, i have made channel 1 for #1, channel 2 for #2 and channel 3 for #3. all use same incremental encoder with 8192 pulse per rev. aside from setting up the feedback here, it is required to set up the encoder convertion table as well so as to getting the correct readings? by the way, the halls are connected.
i hope someone could help to pin point errors being made...thank you for the help in advance.....
