6 FAQs about [The battery pack can drive a three-phase motor]
How many DC batteries do you need for a speed control system?
The entire system will be powered by two large 48V dc battery packs. As the motors are powered from dc batteries we need to convert this to 3 phase ac and then transform it up to 380 and apply a speed controller. But this entire system becomes quite expensive, so instead we are thinking of creating our own conversion and speed-control system.
How much power does a DC to 3 phase inverter use?
The standard DC to three phase inverters are bog standard and not expensive, even offering masses of controllability such as max Hz settings and gearbox ratio input so the output is the shaft speed. The controller is going to be a 2 Watt 5k pot on the dashboard. Use a big knob!
