Hi,
New post here. Just saw something today that got me thinking whether this is practical or not. Using an ABB ACS355 variable speed drive to run a 0.75kW 3 phase motor to run an ebike.
This drive normally taking single phase in and giving 3 phase out can be powered with DC directly to the DC bus via the Brake terminals and then I assume will regen back to the battery when required. The DC bus voltage range is 270VDC - 325VDC.
It has rs232 connection that support Modbus RTU that I was thinking about interfacing to a raspberrypiw zero running node red or something like that which in turn can present an interface to a mobile phone via http. This will be able to display all the information on the VFD for example DC bus voltage (essentially battery voltage), rpm, faults, etc.
Thinking something like 80 - 100 18650's in series.
I'm a sparky and work in industrial sector so the drive and motor is easy to find which is what led me down this path.
Can anyone advise me on whether this is worth exploring further or not? I have access to an engineering workshop and was thinking this could be a fun project for the next little while.
Ideally I can get 60km/hr top speed with a range of around 50km preferred.
One of my concerns is the best way to prevent against electric shock at that voltage in the event of a winding failure to the chassis.
Thoughts?
Thanks.
