I've find this forum after a hard day of searching this motor.
So, I know the existence of one of its variant by this application :
More specification here :
o Four-pole induction, high frequency design with inverter-controlled magnetic flux.
o Dimensions*: 12\" dia x 15\" long (305 mm dia x 381 mm long)
o Total weight: 110 lb, 50 kg (incl cooilng blower)
o Maximum rpm: 12,000
o Insulation: Class H, double-insulated
o Cooling: Forced-air with variable speed pwm control
o Sensors: Winding temp, tachometer
* dimensions exclude blower and connectors
** up to 30 A allocated for cooling blowers
So it would exist an AC motor with an RPM max of 13.000 RPM.
3 phase AC Induction, 150 KW, 4 pole, lot of torque with a total weight of only 50kg ;p;
I'm looking for such kind of speed, but with less power (and less weight ;b; ) like between 50 and 70 KW.
My application will be electric motorisation of a Superkart.
I know it would be simple to drive it with a DC motor but the objective is to get experience for regeneration brake only avaible on 4 quarter AC drives.
Sorry for disturbance ;b; , but very long time i'm looking for this.
