Swap out of Warp 11 DC motor with a Hyper 9DHV 3 Phase Motor.


When the HyPer 9 initially was introduced by Netgain, it was designed for a voltage range between 60 and 130.  NetGains recent introduction of a higher voltage motor HyPer9-DHV (dual shaft high voltage) allows for operation in the voltage range of 90 to 180 volts.  This higher voltage allows the current Tesla based battery pack (6 cells), with nominal voltage of 144 volts, to be used with either the DC or the AC motor.   One of the goals of the build was to create two separate drive trains that can be swapped out with a minimum amount of effort.  In principle, one might be able to drive DC in the morning (high performance) and AC in the afternoon (in cruising mode).  To that end, each motor has now been attached to its own Getrag 5 speed manual transmission, adapter plate, racing clutch, and motor controller.  Using the components previously described in this blog for the Warp 11 drive train,  the adapter plate (8/31/12), hub adapter (8/24/12), and Stage 2 racing clutch (5/3/13)  were all used without modification when combined with the Hyper 9-DHV.  The controller mounting platform, on the other hand, will need to be different to accommodate the different motor and controller dimensions.

In this build the Warp 11 was configured to use the Soliton1 controller, but other brands of controllers could have been used just as effectively.  In contrast, the HyPer 9-DHV can only operate using the factory supplied AC controller that is matched to the motor.

DSC06607 showing the terminal and accessory plate end view.  The motor serial number label is located on the standoff that supports the terminal strip.  In older dual shaft motors (shown) the serial number is sometimes harder to read as it can be obstructed.  updated 8/21/21





In this fresh out of the box picture of a single shaft Hyper9 HV motor, the serial number is much easier to read. updated 8/21/21
