Hi,
We are going to build 3 test benches for mid drive motors. My question is related to controllers with regen capabillity.
I have used controllers from Sabvoton, Kelly and TIs Instaspin FOC development boards - most have been a simple coasting regen, where the instaspin board did full variable regen.
The testing is automated using a microcontroller controlling everything, 1 battery feeding the test bench and 3 motors with separate motor controllers. 1 motor emulating the human input, 1 motor under test and 1 motor for regeneratively braking the motor under test and motor emulating the human.
Pass/fail testing is based on efficiency measurement, temperature check after extended riding and noise level.
Currently I am researching what motorcontrollers to go for. The motors used are around 1 kW at a bus voltage of 36 V. Originally I was planning external power meters - but researching the problem more maybe this measurement can be internal to the motor controllers.
Where is time researching/programming best spent? Is the VESC project the best bet - or are there simple china controllers of fair quality that will do variable regen like BMSbattery Kunteng controllers?
Appreciate any input,
