The latest evolution of our BLDC inrunner modeling has resulted in:
A motor of only 210 mm outside diameter x 250 mm long.
140 Volt 600 Amps max.
400 NM from 0 to 500 RPM and than sloping down to 130 NM at 4000 RPM !
Water cooled and specially winded.
We are now in the price negotiations for the electro steel lamination purchase and cutting.
Once we can make the motor we can measure how long this liquid cooled bomb can deliver its 60KW before overheating. We developed some very "cool" liquid cooling system for the motor, so we hope that it can have a very high power out for at least 8 seconds. By than the batteries (that we can afford) run hot too.
My latest way of thinking to make my Jaguar Hybrid, is to replace the Air conditioning pump by this BLDC-M. I live in a cold country. So it will be geared and from standstill the jag will have 400NM + about 100 NM from the IC motor. You remember our torque discussion: 500 NM geared !
I want than to regulate the throttle so that the electric motor does the hard work under acceleration and than the IC takes over ... Pitty that REG braking will be hindered by the Jags torque converter in the autobox.
