We are recommended BLDC Motor for mobile robot by Dunkermotoren.

Dunkermotoren say that if you use other driver, you should use braking chopper for brake voltage protection.

I think that most of driver include brake voltage protection system.

How about Roboteq drive system?

We want use HBL2360 and 1.1Kw BLDC Motor.

Hello thank you for your question. A braking chopper is used mainly when there are regular intervals of high regenerative current that occur from your motors during braking. The braking chopper serves to dissipate the regenerative energy as heat using a resistor. Our documentation outlines some wiring diagrams that will allow regenerative current to flow back into a battery, but this of course only works if the controller/motors are being powered using a rechargeable battery. If you are not using a battery regenerative current can be a cause for concern and other methods to remove this energy to avoid damaging the controller must be used. If needed a bake chopper can easily be integrated into your circuit. For more information regarding regen, please refer to our article on the subject.

What is your application? Keep in mind that the HBL2360 is only rated for 75A peak per channel.
