I have 3 of these drives that were used in a R+D project a few years back. They were $6K new, looking to get $3K a piece. All are in perfect working order. Feel free to ask questions, and I will do my best to answer them.

Does it come with wiring?
Can you share what was found out during your R&D?
It does not come with the wiring. I could probably find the part numbers of the connectors and pins and order them up if that would be helpful.

They were used to drive some small BLDC pump motors from a 700V battery for a vehicle application.

You might want to mention the exact type, is it for encoder or for resolver?
The Gen4 range of motor controllers can be used across a wide range of applications, for example:

Ideal for traction applications such as mopeds and go-carts, motorbikes, city cars, fork lift trucks and aerial work platforms.
Separate operating modes allow for the unit to act as a fully fledged VCU master or as a simple torque slave unit.
Sevcon Pump Application technology allows the unit to drive a pump motor.
Specialist support for safety-critical power steer applications.
Communication:

The Sevcon Gen4 range supports configuration, calibration, control and status monitoring over a CAN bus using the industry standard CANopen protocol. In order to support a wide range of applications, the unit is able to be configured as either an NMT master or slave device.

Gen4 controllers can be configured to support limited compatibility with a J1939 bus.

To take full advantage of the features of CAN communication on a Sevcon product, an IXXAT CAN to USB device with Sevcon DVT Software subscription will be required.

Ingress Protection:

The Sevcon Gen4 range is IP66 rated, providing total protection against dust ingress and protection against water ingress during high powered pressure washing.

Motor Support:

The Gen4 range provides support for the following motor types and control modes:

PMAC
Induction machine (Openloop Slip Control)
Induction machine (Flux Vector Control)
Encoder Support:

The Gen4 range provides support for the following sensor types:

A
AB
UVW
ABUVW
Sin/Cos (Specific hardware only)
Resolver (Size 8 and 10 models only)
Connectivity:

Power connections are made through M8 terminal posts. This includes the DC link from a battery or other source via a fuse (mounted on-board) and 3-phase output to the motor.

Signal connections are made through a 35-Way Ampseal connector. Signal connections include:

1x Encoder connection (power supply and signal connections)
2x CAN bus connection (internally linked. Termination available)
8x Configurable digital inputs
4x Configurable analogue inputs
3x Configurable contactor driver outputs
1x Thermistor input
5V and 10V power supply outputs (Specific hardware only)

Does it come with dealer support? What motor is it setup for?

if with dealer support: where (about) is dealer located?

What kind of encoder do they support?

Why is the housing reworked with the extra aluminium pieces by the connectors?

These are great controllers, but getting support can be difficult.

It's a lot of money, so if you can provide support that would help a potential buyer.
