60 volt controller & motor

Hi to everyone, I'm working on upgrading an electric scooter and wanted to know if anyone has a 1500w 60v controller and a matching motor. Or know where to get one that won't ask questions when it pertains to shipping to Canada and our laws about power ratings. The rear rim it has to fit is 16" diameter. The white one is the one I need the parts for.

Ordering Components

After talking to a fella at EV works about various components I have settled on parts for my bike.

Motor: This is the less complex and slightly more powerful out of the two 48V motors. http://www.evworks.com.au/index.php?product=MOT-MARS-ME0708

Batteries: At the moment I'm getting 11 of these cells and will update later to 16 so I get the full 48V system. These will take about 6 weeks to ship so lots of time to draw up some concepts for attaching them. http://www.evworks.com.au/index.php?product=BAT-LFP60AHA

Controller: This one gives the best acceleration for my price range. http://www.evworks.com.au/index.php?product=CTL-AXE4844

Contactor: Good economical option. http://www.evworks.com.au/index.php?product=REL-ZJW400A

Charger: KP3612EL is not currently stocked so will have to wait for that. The charger will be the only component I will need to replace when changing up to 48V.

Battery Management System: Another component I need to wait for. EV works are developing a new, more compact BMS which should be ready in a couple of weeks.

Braided Cell Interconnectors: http://www.evworks.com.au/index.php?product=BAT-EVW-BCI-60-6

Fuse: http://www.evworks.com.au/index.php?product=FUS-ANN-250

That's all I'm ordering at the moment and these parts, including shipping from Australia to NZ, should cost about NZ$3800 (US$2800). I'll be getting other things like DC-DC converter, gauges, power cable and lugs from an electronics store in NZ once the bike starts to take shape.

Mini-golf cart controller problem - help!

I've got a controller out of a fairly new 4 wheel Chinese mobility cart (has a steering wheel and looks like a tiny one seat golf cart). The part # on the controller is CID 932 B9D. It is a 10 connector controller (one connector is not used) with built in reverse - 36 volt 40 amp with the 31.5 voltage protection. The controller looks identical to a CT-660B9, but with 10 connectors. Any Idea where I could locate one if these? Is there another controller that I could use (and not have to do extensive modifications?
Any suggestions would be appreciated.

The Rezistor - controller issues clarified

On Sunday I contacted Dan at Team Delta, who sold me the motor and controller. I described what was happening with the Sevcon Millipak controller and he was able to clarify things for me.

Issue 1: I could accelerate only very, very slowly, or else the system would shut down and the controller LED gave me a 9-flash error message, or "rotor position sensor fault". Turns out that I chose one of the initial controller setup parameters incorrectly. The controller uses current sensing and Hall effect feedback to servo the motor in either speed or torque mode, and I chose the speed mode when I should have picked torque. I don't have the equipment to change the setting, but Dan said he would put another controller in the mail to me on Monday with the correct setting.

Issue 2: I turn the keyswitch and I hear no "click" from the contactor engaging, and only get a 3-flash error message from the controller LED. This indicates a MOSFET short-circuit, which is internal to the controller. Dan indicated that the failure of the contactor to close confirms that this is the case. So, it's a good thing he's sending me a new controller anyway. He also mentioned that this is only the first out of about 58 of these controllers he's sold that has failed in the field.

So while I'm waiting for the new controller to arrive, I've been working on my front turn signals, using my usual medium of LEDs, acrylic plate, and 5-minute epoxy.
