I’ve never heard of a 750 volt motor. What’s the deal with that? How do they even get the voltage that high?

- michael1999 5y agoTwo 12-volt sources in series yield 24 volts to the circuit.

- simonblack 5y agoHow do they even get the voltage that high? The same way as any other battery, just increase the number of cells. Most cells seem to run between 1.5-2 volts. A 12 volt car battery is usually six cells of 2 volts each.
- foxyv 5y agoFor the motor: A lot more insulation on the coil windings mostly. Higher voltage usually means less copper needed and more insulation. Boosting voltage from batteries is pretty easy. Either using a transformer on the motor controller or putting enough cells in series to get the voltage you want. There are also methods using inductors and PWM to get a boosted voltage. 750 volts is actually fairly low. Siemens makes some 3-6 kilovolt HV motors. https://hv-easy.azurewebsites.net/ https://hv-easy.azurewebsites.net/
