My friend and I are doing a sort of academic research about heavy electric vehicles. A sub-project involves choosing the wheel motor and defining the control method.
Aside from what currently exists on the market (this is academic research) we are interested in debating why one solution is preferred above the others (or the pro/cons of each one.)
The main design requirement is the motor power: 50kW to 100kW.
The other important factors for the motor are:
- Construction complexity
For the control unit:
- Weight (e.g. due to big heat sink)
Currently, modern technology pushes towards BLDC but we need to explain WHY it is better than other alternatives. We currently considered as a possible alternative an AC motor + inverter (or induction motor?)
My questions are:
- What are the pro/cons of one compared to the other?
- In case of AC motor + inverter, could be the inverter be a PWM generator and using the engine coil as low pass filter to optimize everything? yes/no/WHY?
- Can you please provide reference literature? I investigated myself but most are just one page sheet which just tell the generic stuff about this or that.
