[QUOTE="oexing, post: 120439, member: 1493"] I tried one of these typical motorbike regulators on my own setup with three phase brushless 48 V servo motor, 300 W for its job as generator on the Vincent. When I did a load test exceeding 14 V with a quartz bulb the motor started to emit some unhappy sound and motor and regulator went to unacceptable temperatures from there quickly , I had no cooling in the test jig. So I did some research in Google and learned that these simple regulators just short one or two phases in the three phase permanent magnet alternator or turn all power into heat above the specified 14 V. So really no question for me to stay with this crap. So I came to the idea to let the alternator do all voltage it can produce and not cut off at 14 V - you will get some more power as well. So really the 48 V motor will turn out more than 50 V and some 300 W . For taking the job of the miserable bike regulator I had a three phase rectifier 20 A 1200 V on the motor/alternator and a voltage converter for getting the 13.8 V for battery supply, both items at € 35.- from Ali. . When you look up the old thread from last year you will see that NO extra cooling is required for these two components , nor for the alternator on the Vincent. And this at over 200 W load in half an hour no cooling in my workshop. So the Podtronics don´t impress me much if cooling is critical with them.
