Siemens 1PV5135 4WS14 AC Induction Motor

This is perhaps the most unusual AC Induction Motor in the world. Siemens makes extremely high quality heavy duty AC induction motors - mostly for yachts and busses, but some trains as well. This motor was specially produced for the Azure Dynamics Ford Transit Connect project and we obtained a large lot of these motors, brand new in the box, from the Azure Dynamics liquidation auction.

What is so unusual about these motors is that Siemens typically designs very high voltage (600-750v) three phase AC inducdtion motors. This motor was specially produced for AZD and is wound for a relatively low 215vdc.

This motor was bench tested to 297 nm, 221 ft lbs at 300v and 400a.  These motors dyno test in vehicles at 134 horsepower.

A few years ago a large lot of Siemens motors from the Ford Ranger Electric project were similarly available and they went like hotcakes. But they had a LOT of problems. It featured a very unusual and hard to deal with shaft and the front bearing was actually open to allow lubrication directly from the Ford differential it was designed to mate with.  You had to replace the front bearing with a difficult to find replacement to use the motor at all and you still had to deal with the geared shaft.

This motor needs no modification. It has a very usable 24 tooth splined shaft and is fully sealed. This is a HEAVY duty motor, like 190 lbs of heavy. IP67 sealed and features liquid coolng - glycol and water. IT withstands great abuse to the degree you cool it. And we have a great cooling kit available for just such purposes.

All the advantages of OEM quality maintenance free AC induction motors at the DIY conversion price.    

Note that Siemens does not provide any warranty or support for these motors.  They are part of a liquidation sale.

This unit is tagged at a nominal voltage of 215 volts and a continous power rating of 47kW which is somewhat at variance with the data sheet on this motor.  These appear to be specially wound for Azure Dynamics eTransit Connect program.  It was paired with the Azure Dynamics DMOC645 Inverter which is rated at up to 414 amps and 118 kW.

Liquid cooled: 50% glycol/water at 16liters/minute.
Requires a three-phase inverter/controller.

Azure Dynamics Force Drive DMOC 645 InverterAzure Dynamics Force Drive DMOC 645 Inverter

Azure Dynamics Force Drive Digital Motor Controller (DMOC) Model 645

This is the Azure Dynamics 3-phase AC Motor Inverter.   This device is controlled by CANbus messages to drive the Seimens 1PV 5135-4WS14-Z AC Induction Motor.

Azure Dynamics was liquidated in November 2012 and we acquired a quantity of these in a liquidation sale. These are orphans as  there is no product support, warranty, or repair services from the manufacturer for this inverter.  

It was specially configured for the Ford eTransit Connect vehicle, and has no software to allow a stand alone operation.  It  requires a Vehicle Control Unit (VCU) to translate driver inputs into appropriate Controller Area Network (CAN) messages to control the inverter.

This is the configuration  used in our VW THING build and it works quite well, developing about 145 horsepower with the Siemens motor..

Borg Warner 31-03 eGearDrive 8.28Borg Warner 31-03 eGearDrive 8.28
 Borg Warner 31-03 eGearDrive.

 This single speed transfer case was developed by Borg Warner specifically for electric drive applications.  It has emerged as THE drive train choice for modern electric vehicles. It was used by CODA with the UQM drive train and by Azure Dynamics with their eTransit Connect.  Aptera and the Tesla Roadster also used this gearbox. The 8.28: 1 drive ratio is perfect for single ratio electric vehicle applciations. 

Ideally suited for full performance electric vehicles on either front-wheel drive or rear-wheel drive transverse driveline applications, the BorgWarner 31-03 eGearDrive(TM) single-speed transmission delivers high torque capacity, high efficiency, and low noise, vibration and harshness (NVH) in a compact package. 

Named a finalist for the 2010 Automotive News PACE Awards, BorgWarner's eGearDrive™ transmission incorporates patented and proprietary technology as well as over 100 years of powertrain know-how. Through its high-efficiency gear train and compact, low-weight design, the BorgWarner eGearDrive™ transmission contributes to extended battery-powered driving range which in turn reduces the required amount of battery capacity needed. The transmission also achieves high torque capacity in a compact package with greater than 97% efficiency, while providing smooth, quiet operation. Approximately 99% of the materials used in the eGearDrive™ transmission are recyclable.

BorgWarner's 31-03 eGearDrive is a purpose built, high performance transmission that can be broadly adapted to a variety of electric propulsion systems," said John Sanderson, President and General Manager, BorgWarner Drivetrain Systems. "Designed for fast-to-market implementation, we expect this eGearDrive transmission to accelerate growth in the all-electric and hybrid electric vehicle segments." In addition to providing primary drive for front-wheel drive and rear-wheel drive electric vehicles and hybrid electric vehicles, BorgWarner eGearDrive systems enable launch assist, energy recovery, and AWD performance for the secondary-driven axle on any type of vehicle. Also available is an optional electronically actuated park lock system as well as various electronic driveline disconnect systems.

We acquired 16 of these from the AZD auction and they are perfectly mated to the Seimens 5135 motors and includes a shaft adapter for this motor. 

We have been able to resupplly from Borg Warner but unfortunately not at the liquidation price.
