High-Power BLDC Driver/Controller for Transportation EV

Other Parts Discussed in Thread: UC2907Hello Expertes, I have a 6x6 using 6 BLDC Motors 24V/2kW with BLDC-Drivers from the Motor-Manufacturer in China. OK, it works, but it could be better. I am ongoing to desing a special transporter for Mobil-Homes/Offices (7,45x3m) and the transporter will have nearly 12m in lenght So I need 6/8 Full Axis using one BLDCs of 5kW/Axis or 12/16 Semi-Axis using BLDCs of 2kw/Wheel. I have choosen a Hercules Microcontrooer as Central Unit and want o use CaN to controll the BLDC-Driver/Controller. So, now when it comes to the BLDC Motors, I have 24V 2000W 36V 3000 - 5000W 48V 4000 - 7000W 72V 5000 - 17500W Also I use ONLY A SINGEL POER RAIL of 24V, 36V, 48V or 72V for the LOAD and CHARGING of batteries, which mean, the Power Rails are Bi-Directional The Power-Supply are Self-Developed "HighPower LiPoly SmartBattery", using cells of 3.7V/10Ah e.g. 24V (30cells), 36V (32cells), 48V (30cells) and 72V (30cells), geive each arround 1100Wh which can be paralelized using CAN which give in theorie up to 120 SmartBatteries or up to 130 kWh (NOTE: I do not use the TI Load Share Controller UC2907//907 or UC29002/9002) The questions are: 1) Is the "Brushless DC (BLDC) Motor RDK" (RDK-BLDC) suitable for the project? 2) Does someone have Application Notes or Reference Designs für BLDC Motor controllers which support up to 72V and 250A? 3) How to use the reverse power while "break" is active? NOTE: The motors can several minutes overloaded to 200% so the current can be twice as high. You can also contact me by E-Mail: michelle.konzack@electronica.tamay-dogan.net Thanks in advance Michelle
