### Mixing Motors?

Posted:

**Thu, 31 Jul 2008, 18:33**Of the examples I have seen where two motors have been used; all of them have been two of the same kind of motor i.e Warp 9 + TransWarp 9. Is there any reason why two different motors couldn’t be used i.e Warp 9 + TransWarp 11?

Just elaborating on this…

The reason I was asking was I am looking to build an EV with some reasonable grunt but due to space limitations I may need to compromise of the motors used.

Since I will need to spend some reasonable dollars to get reasonable grunt I have been giving thought to the AC90 as an alternative to a DC setup.

Specifications

Peak Torque Nm 665

Continuous Torque* at Nominal Speed Nm 330

Nominal Speed Rpm 1350

Maximum Mechanical Speed Rpm 5000

Maximum Current A rms 414

Continuous Shaft Power* at 1000-2500 rpm kW 50

At a voltage of VDC 312

Peak Efficiency % 94

Peak Shaft Power kW 97

At a voltage of VDC 312

Weight AC90 Kg 189

Weight DMOC645 Kg 27.5

Diameter AC90 mm 394

Length AC90 mm 520

Length DMOC645 mm 585

Width DMOC645 mm 260

Height DMOC645 mm 310

Minimum Recommended Nominal Battery Voltage VDC 312

Maximum Nominal Battery Voltage VDC 336

Minimum Operational Voltage VDC 100

Maximum Operational Voltage VDC 400

Maximum Voltage “On Charge” VDC 450

Minimum/Maximum Operating Temperatures ˚C -40 to 60

When I first saw the weight I thought it might be a little on the heavy side until I started researching engine weights.

Obviously this would be totally in appropriate for a lighter car, but since I have always fancied the 300ZX it might make a suitable replacement for the heavy VG30DETT and gearbox.

I figure motor and gearbox has to weigh at least 300kgs…

It would have a mountain of torque but would there be sufficient power?
