Re: Buick Lacrosse 2012 e-assist moto-alternator

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

Re: Buick Lacrosse 2012 e-assist moto-alternator

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-bhar ... ine-coach/ They're available at salvage yards: http://www.sellabus.com/bluebird_parts.html

Re: Buick Lacrosse 2012 e-assist moto-alternator

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

Re: Buick Lacrosse 2012 e-assist moto-alternator

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 motor...

Re: Buick Lacrosse 2012 e-assist moto-alternator

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 frequen...

Re: Buick Lacrosse 2012 e-assist moto-alternator

The motor is working extremely good in the delta configuration with the 550 A Inverter (38 HP config), you can see my e-kart project here: Of course with the +50% current usage the efficiency decreases (up to 65% in worst case) and heat increases. Radiator and water pump are mandatory, but the good...

Re: Buick Lacrosse 2012 e-assist moto-alternator

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!
