  Ok... what happened to the 2 wire rotor leads? Care to share the speed controller spec?

  It's connected to the 12v car battery just to energize the electromagnet, controller is a 500 watt 36/48v brushless

  @SuperFredAZ4 күн бұрын

  fundamentally a motor and generator (yes generator) are the same. A car alternator is a 3 phase motor/generator with a field winding that needs to be energized. When used as a generator the device produces 3 phase A.C. which is rectified by the diodes embedded in the device. Alternators are not especially good as motors since they require 12 V (Usually) at 1-4 amps wasting as much as 48 watts in the field winding.

  No probably be slower but might have higher torque, it has to be driven by 36v and up

  What amp output is the alternator? Do you need to match it to the controller? I'm thinking of making one for a diy, electric powered go-kart. I can get a second-hand 180amp alternator for around £40.

• 
  @rextech429 ай бұрын

  Doesn't really matter how many amps the alternator has but what matters is how many watts it can produce, so if a alternator can produce 2000 watts, that means a 2000watt controller can run it. I'll be making another homemade motor using a faulty car alternator soon so stay tuned

• 
  @Mickparrysstepdad9 ай бұрын

  @@rextech42 Ok, I've subscribed. A quick google search says - "If you want to convert amps and volts to watts, simply multiply the amps and volts." - So my theoretical 180 amp alternator x 12v = 2160 watts. Would that mean I'd need higher than a 2000 watt controller? (sorry for the stupid questions)

Do you any secret squirrel path to a quality supplier (Ebay ) of 800 W or 1000W BLDC controllers , espec those that will work without a Hall line. Do you know if it is practical to add extra MOSFETs inside of an existing controller in // to the existing ones to achieve a higher rating if I can't find that 800 W or so controller.

  If you put some capacitors between the battery and the load, with the battery looped to the capacitors and the motor looped to the capacitors, it will take the load off the Battery and not heat up the battery or motor as much I think.
