The maximum operating voltage of the TransWarP 9 is 170V to the armature. If the motor sees voltage higher than 170V for any period of time, it will arc incrementally worse as the voltage increases. The user can split the voltage of a 350V pack between two NetGain motors wired together in series. This will allow the maximum 170V to each motor, and they will both see the full amperage supplied by the controller.

Amps are the larger source of heat buildup. High voltage will cause poor commutation (arcing) where high current will cause more heat buildup within the motor. So additional cooling will not offset any higher voltage, but it will allow for higher current over longer periods of time. Current ratings for the TransWarP 9 (with no external cooling) are shown below:

        2000 Amps for short periods (seconds) of time...

        500 Amps for 5 minutes

        250 Amps for 1 hour

        200 Amps continuous

Here is the general rule for motor to vehicle weight:  (Please note that terrain, coefficient of drag, frontal area, tire diameter, rolling resistance, gearing, etc. also affect these #'s, and they are NOT cast in stone - your results may vary...)

 

Direct Drive Motor Selection*
Motor	Vehicle Weight	Dual Coupling Motor	Vehicle Weight
Impulse 9	TBD	TBD	TBD
TransWarP 7	1,400 lbs	WarP 7	2,800 lbs
TransWarP 9	1,750 lbs	WarP 9	3,500 lbs
TransWarP 11	2,100 lbs	WarP 11	4,200 lbs
TransWarP 11HV	1,900 lbs	WarP 11HV	3,800 lbs

 

The use of a transmission allows you to double the figures of the first table:

Transmission-ed Vehicle Motor Selection
Motor	Vehicle Weight
WarP 7	2,800 lbs
WarP 9	3,500 lbs
WarP 11	4,200 lbs
WarP 11HV	3,800 lbs

*Direct Drive assumes that a differential with additional gearing is being utilized.
