   CONVENTIONAL VEHICLES versus ELECTRIC VEHICLES

   The idea of this video, each time I turn my ignition key..... It started with my Fendt tractor from 1963 and it ends with my Rover75 from 2006. So, what I am doing there, since 1963 until today nothing changed! Nearly all combustion engines are noisy, dirty and needs a lot of maintenance! :(...

   CONVENTIONAL VEHICLES versus ELECTRIC VEHICLES

   Maybe some things never change. Nearly all combustion engines are noisy, dirty and needs a lot of maintenance. I think, the electric motor is the better choice. The best selection is an unlimited range vehicle, but that doesn't exists or does it ??? OK, here the video..... _H34LnwuIHw

   SOLUTION FOR MORE MOTOR-AMPS

   YES, this controller is full programmable and with 8xIRPF4110 TO247AC FETs. 6 FETS are for the motor control and the other 2 FETs control the recouperation of the brake. For example, I can program via USB connection the voltage, amps, speed, pedal sensor 1/0, sinus/block, reverse gear...

   SOLUTION FOR MORE MOTOR-AMPS

   That's only a bolt!!!!! You get bolts from M3(3mm) until M40(40mm) and more, and of course in every length! What I needed was an axle with a strength category of 12.9, so it's a misappropriation of this bolt. BUT you will not find this bolt into a DIY, it's from the bridge engineering...

   SOLUTION FOR MORE MOTOR-AMPS

   NO! The showing measurement is with a electronic amperemeter pliers. The incoming AMPs to the controller are DC and the outgoing AMPs to the motor are AC. With the programmable controller I can select between block-mode or sinus-mode.

   SOLUTION FOR MORE MOTOR-AMPS

   Hi, it's me again... I've tested out, that the most loss is not in the controller or in the coils. It's in the cable of the motor!!! Ok, in the following pictures you maybe see more details...

    AIRCOOLED BRUSHLESS DC MOTOR

    @gogo I've tested the normaly 36V/500W hubmotor in a "burn out" with about 1500Watts. The battery voltage in the operation was 38.6Volts, the limited current was exactly 40Amps. The controller with the tunnel heatsink has got 46Celsius, the motor only 32Celsius. Ambient temperature was...

    AIRCOOLED BRUSHLESS DC MOTOR

    @ BiGH It's normaly for an industrial application. I think, it's not easy to find. BUT, you can use all RADIAL BLOWERs, you got these in a computer shop. The radial blower produces more pressure than a axial blower. Then it's easier to handle, there isn't a slope of the air flow(stall)...

    AIRCOOLED BRUSHLESS DC MOTOR

    Nearly everyone knows coil smell, to avoid that, an electric motor must be good cooled! The problem is the staying heat into the motor. Another problem is that the heat in coils change the resistance (ascending) and you will lost a lot of power. In the following videos I've created a little...
