HBL1650 current 150A was created by Trainee
Hello,

I am using a HBL1650 controller and I am a little confused with the '150A' in the user manuel. Does it means that the controller is able to output a maximum current of 150A? Or is there other explanation? Because when I tested it I saw in the Roborun+ channel section in the 'run' page that the battery amps and motor amps never exceed 10A.

Another question is that what's the difference between battery amps and motor amps? Are they suppose to be the same? Can someone explain to me please?

The user manual has the information you are looking for, page 28 and 29. Please take some time to read it.

150A max is the max current(motor amps) the controller will put out for 30s should your motor actually draw it out.

The battery current is measured and the motor amps is calculated from the battery current. At less than 1A, the motor current will not be accurate.

Thanks a lot. When I applied a motor command less than 200 out of 1000, I got 0 for both motor amps and batt amps. Why is that so?

Another question is that : Is the controller volt in the Roborun channel equals to the motor voltage? I am using a three phase dc brushless motor.

What I don't really understand is that when I change the motor command, the controller volt is always at 13.4V, even when motor command is 0. Why is that so?

I saw in the user manuel page 186 that ?V allows to read "the internal voltage at the motor driver stage". What does this phrase means?

The motor output is a PWM output. Therefore the voltage at the motor is going to x% of the input. So if a 12V battery is used, then at 0 command, the voltage is at 0. At 50%, it would be 6V, and 100%, it is 12V. The battery current is measured and the motor amps is calculated from that. Anything less than 1A is a not accurate reading.

If your motor is not loaded, then it may take a bigger command to draw the 1A or more.

If the controller is good, then controller voltage will always be 12-13V. If it is less than that, there is a problem with the controller. This is internal to the controller itself.

Your last question goes back to the said statement about the controller voltage. It is not something you need to spend any real time worrying about.

The controller does not measure the voltage at the output; that is something you can do externally with a voltmeter.

Thanks a lot. Is the motor amps equivalent to the root mean square value of the current that runs in the motor?

Take a look at page 28 and 29 of the user manual.
