working of 3 phase inverter in regeneration

Hi Mohit,

What are the voltage and current specifications?

Hello,
Thank you for replying.
I am having BLDC hub motor that is supplied through batteries.
BLDC hub motor is 48V, 500W and I am planning to put it in regeneration. For this I am looking an evaluation board that can allow the current to flow in both direction. Till now we have operated motor at 2.5A.

Hi Mohit,

What is the maximum battery voltage when fully charged? The margin could be reduced significantly if the fully charged battery is ~56V.

One of the applications of the DRV8301-HC-C2-KIT is E-bike.

The DRV8301 has a recommended maximum voltage of 60V and absolute maximum voltage of 65V.

Hello, 

Do the kit that you suggested work during regeneration? 

Max battery voltage is 48V. 

Thanks

Hi Mohit,

Please see post e2e.ti.com/.../306254

Hello,

I read details about DRV8301-HC-C2 kit. This kit has C2000 Piccolo F28035 MCU controlCARD that helps to control the motor speed. Is that possible to change the control card in this kit. IS there any control card that can help in position and speed control both.

This kit has sensorless trapezoidal commutation can it be done by sinusoidal commutation.

As the controlcard comes preflased, using GUI it is not possible to control the position of the motor. So, is it possible if i load my own program in the control card. If yes how it can be done?

Thanks

Mohit

Hi Mohit,

Yes it is possible to change the control card. Please look at MotorWare ( www.ti.com/.../motorware ) for additional information.
