    Has anybody done any more work trying to use the stock controller(or other controller) with the eAssist motor?

    Electromagnetic retarders are used as auxiliary brakes on heavy duty vehicles. Here's one on a new bus chassis:https://www.cvnews.in/say-hello-to-bharatbenz-1623-front-engine-coach/ They're available at salvage yards: http://www.sellabus.com/bluebird_parts.html

    Did the people you talked to say why you should use the Curtis, and not the Sevcon?

    I would think the iron losses and loss of efficiency would be unacceptably high at those high of voltages. I saw somewhere a Sevcon Gen 4 G9930 controller rated at 300A peak, 120A continuous, 150V max, 500Hz max stator frequency. By my calcs., this potentially could give a max 7,500RPM. In the...

    Thank you, Great stuff! Is the 4000rpm limit because of the 300Hz stator frequency limit of the controllers? In higher voltage applications, assuming iron losses are not too big a factor, this could be a problem with this 8 pole motor. Does anyone know if other controllers have higher stator...

    Thank you for your response. If you have the cooling system set-up (radiator, hoses, pumps,etc.), could you post some photos of it so we can get some idea of what would be needed? Also, could you post a simple spread sheet of the controllers(model, voltage, and current rating) you're using (...

    What's the latest on this motor hack attempt. Were you able to get the motor up and running? I'd be interested in the potential overheating issues with the high power levels you were reaching. Great work, by the way!
