I am donating 50% of the sales to the America Red Cross through ebay!
I bought this brand new controller 6 months back to power my AC24LS motor for a DIY EV (electric vehicle conversion). I was going to do a AWD plug in hybrid conversion but I just got a DMOC that came with an AT1200 that I am using instead. This is a 550amp controller with a maximum voltage of 130V and a peak of 72kW. That extra voltage give you you more power as it maintains the torque to higher RPMs when compared to the 80V (108 max) controllers on ebay. This is a controller for an AC motor and this controller does do regenerative braking.
I'll even give the option to the buyer to buy a brand new AC24LS (or a used AC24) motor with a standard 1.125" keyed shaft to work with may different adapters.
This means you could have a AC motor AND this controller for ~$2000!
The wining bidder has the option of buying the accessories I got for it after the auction:
LEV200 Contractor - $125
Curtis Wiring harness - $80
Curtis USB programmer - $480
Only Curtis AC can offer:
• Curtis VCL -Vehicle Control Language is an easy to use programming language that allows vehicle developers to write powerful logic functions and create a ‘virtual system controller’. Curtis offers customers VCL development tools and training. Curtis also provides a VCL service where Curtis engineers will work with the OEM to create any custom VCL code required.
• Indirect Field Orientation (IFO) vector control algorithm generates the maximum possible torque and efficiency across the entire speed range. Advanced Curtis IFO vector control provides superb drive ‘feel’, improved speed regulation and increased gradeability.
• Curtis Auto-Tune function enables quick and easy characterization of the AC motor without having to remove it from the vehicle. Curtis AC controllers are fully compatible with any brand of AC motor.
• Dual-Drive functionality is standard, allowing correct control of vehicles such as 3-wheel counterbalance trucks or other applications featuring twin traction motors. This function ensures smooth and safe operation, minimal tire wear and correct load sharing between the traction motors at all times.
• Configurable CANbus connection allows communication with other CANbus enabled devices. These models are CANopen compatible and can be further customized and configured using VCL.
• Integrated System Controller - More than just motor controllers, they are also powerful system controllers. They feature a comprehensive allocation of multi-function I/O pins for use as analog inputs, digital inputs, contactor coil drivers and proportional valve drivers. In addition to this local I/O, these controllers can use VCL to map and configure the remote I/O available on other CANbus devices, send messages to CAN displays and thus control and monitor the entire system.
MODEL 1236/1238
AC INDUCTION MOTOR CONTROLLERS
FEATURES
Advanced functionality, compact power
• High frequency, silent operation across the 0–300Hz stator frequency range.
• Models available for 350–800A output at 24–96V system voltages. These are true 2 minute RMS ratings, not short duration ‘boost’ ratings.
• Powerful operating system allows parallel processing of vehicle control tasks, motor control tasks and user configurable programmable logic.
• Advanced Pulse Width Modulation techniques produce low motor harmonics, low torque ripple and minimized heating losses, resulting in high efficiency.
Patents Pending
Unmatched Flexibility
• Programmable for either traction or pump applications.
• Field upgradeable software.
• Integrated Battery state-of-charge algorithm and hour meter.
• Multi-ModeTM provides user-selectable vehicle operating
profiles.
• Fully-featured generic software and VCL for typical
Warehouse Truck applications is included.
• Comprehensive programming options and VCL allow other
applications to be easily supported.
• Curtis hand-held or PC Windows programming tools provide
easy programming and powerful system diagnostic tools.
• Integrated status LED provides instant diagnostic indication.
Robust Safety and Reliability
• Insulated Metal Substrate power base provides superior heat
transfer for increased reliability.
RETURNS
• This is a very robust controller originally designed to operate in mines! But it is a complicated electronic component so there are no returns.
