Hi guys,

I have a few Tesla Drive Units that I need to sell. They are both front and rear induction drive units from ~2016 MY vehicles. They're all the ~250-300hp version.
I have hacked them and will offer them "ready-to-run," along with a basic wiring harness and supporting components (main contactor, precharge circuit, etc.)
They are hacked using Johannes Huebner's controller design with the newest firmware. The PCB was designed by Damien.
The boards are soldered myself from blank PCB's as well as flashed with the newest firmware. Wifi access is working for configuration and monitoring.

I've been holding onto these units for about a year but now need to sell them for some cash for new projects.

Huebner's motor control design has the following features:
-It just works. Sine / Slip control for smooth performance.
-Main contactor drive and precharge control.
-Basic configurable interface for universal BMS support.
-Easily programmable CAN interface where CAN parameters can be sent or received via simple configuration using the web interface
-programmable PWM drive to drive a tachometer, motor temp gauge or anything you can think of.
-Wifi interface
-RS232 interface

My goal is to make it as easy as possible for someone to integrate this into their custom project - for those who may be a little daunted by wiring or hacking their own drive unit, but don't want to go the full-on (and expensive) custom shop build.

The only thing you need to add to make the motor run is a high voltage battery and a throttle. Just hook it up and it will run. Many OEM throttles can be made to work without modification.
A BMS is obviously highly recommended but not an absolute requirement.

I have both front and rear drive units. They are identical in terms of performance. They only differ in their mounting arrangement.

For the basic package, the following things will be included:
-Motor/Inverter
-Basic wiring harness to interface with the inverter to supporting components
-Main contactor
-Precharge relay and precharge resistor
-5 hours of phone (or in-person if your PNW) support to help with your custom project
-30 day warranty

I have extensive experience withcustom EV conversions, components design, hacking drive units and multidisciplinary engineering design.

It's a no-brainer to go with one of these hacked Tesla drive units over an HPEV's setup. The performance and efficiency advantage is huge.

I'm asking $4,500 each per package. Shipping is possible @ ~$300-$500.

How can I get more info on the specs for these units, I. e. physical size, torque curves, etc. I'm pretty ignorant about them. TIA

There are some great CAD models here if you need any dimension: Tesla CAD Models - openinverter forum
If you don't use CAD, let me know if you need a specific dimension.

in terms of absolute limits, I don't think much has been published in terms of torque curves. That said, the software is fully configurable and you can tune for any torque curve you desire. You can achieve peak torque at zero speed and peak power can be maintained for a large RPM range due to the ability to control the rotor flux. Expect higher power at higher voltage (max 405V)
