Hi all
First post here, i'm studying for my Motorsport engineering degree which is effectively just an applied mechanical course so my electronics knowledge is there but not very deep
We have a Project to implement the regenerative aspect of KERS on a r6 motorbike. We have a small 2.2kw outrunner motor as a test motor. The aim to rectify and regualate this before charging capacitors.
When you short out 2 or 3 of the leads from the motor, the motor becomes a brake and you can feel this, however when i built a bridge rectifier with 6 schottkey diodes the motor no long brakes when the two 'dc' terminals from the rectifier are shorted. I understand that the torque in the motor is proportional to current which matches up with the motor locking with a dead short. I was expecting the same behaviour by shorting the wires after the regulator.
I have 60A 600v diodes which I suspect may be the problem as they will have some leakage and 1-5% of 600V is alot for a DC system.
Hooking the output of the regulator up we get 5V which is expected from the 200kv motor hooked up to a cordless drill at 1500rpm - ish however the measly 1A is causing no noticeable braking on the motor
Any help would be greatly appreciated
Thanks
