TransWarP 9 ™ Motor

This motor has an 9.25" diameter. It is a series wound DC motor with a double ended shaft. Our TransWarP 9 ™ motor has been designed to ease the conversion process for people who want dual motor and/or direct drive applications. It has many unique features that set it apart from any other EV motor currently manufactured.


This motor has a "shorty" tail shaft housing from a Chevrolet Turbo 400 transmission fitted to the drive end-bell (may be ordered with or without housing!) This is because the drive end shaft is not the typical 1.125" single-keyed type, but rather a hefty 1.370", 32-tooth involute spline that is identical to the tail shaft spline of a Turbo 400 transmission. In other words, this motor was designed to replace a transmission and couple directly to a drive shaft!

We have added double wide bearings on the drive end, added grease fittings (as you now have a slip-yoke assembly...). We use the industry standard 1350 universal, so you can easily adapt it to any manufacturers drive shaft! The motor also has brush wear indicators and a temperature snap switch. It has the same high efficiency fan and massive commutator and brushes as the WarP 9 motor. We even made the commutator end shaft the same diameter as the drive end of a typical WarP 9 - just in case you wanted to connect 2, 9" motors together! 

We also provide 2 lifting holes.

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
