I am planning an EV conversion and have been looking at different motor options that would be feasible to use. One possibility that i have been investigating is using a standard industrial motor. The main limitation encountered with these motors are the weight and the rated rpm and hp. On...

Forgive me for being vague. I am very aware of the danger involved with working with this level of voltage. I intend to run whatever designs i have on a spice program before actually building the componenets. I am just trying to go from this large bus voltage down to about 12-13 volts that i can...

what is the most efficient way to pull voltage off a large dc bus(230-400) to power a control board

I am now looking at an ac induction servo motor rated @18.5kw,105Nm of torque, 2000rpm, 69 amps up to peak torque of 300,8000 rpms. It is 260v motor. What is the realtionship between torque and hp. This motor wil have plenty of torque for my needs, but is it possible to use space vector control...

Do you know the formulas for figuring hp and torque for a motor if i run it at higher frequencies and voltage.

I am impressed with your knowledge of motors and their controls. It is helpful information going forward. What I am uncertain of is what can be done on this particular motor model (Marathon Black Max - 30hp - inverter duty) to achieve greater performance. From what i have read inverter duty...

The appllication will be for an EV vehicle.

I am looking at the ac induction motors that some of the major ev cars use and they weigh only 200lbs or so but are rated at 50-60kw constant and 100-125kw for short periods of time. Is there any way i can take a widely available inverter duty motor(i.e. Marathon Black Max - 30hp) and get even...

how can i get greater performance from an standard inverter duty motor( marathon black max). I am in the process of buiding an inverter/controller to use as part of an EV conversion.
