Hi, I wasn't sure to place this question in engineering or physics, but it seemed more an electricity & magnetism question.
I am attempting to build a bicycle pedal-powered generator. A bicycle stand's roller will move the DC motor's (aka generator's) shaft. I understand I will need a blocking diode (with a large heat sink) and also a voltage regulator and a pair of 12v batteries (it's a 24v motor)...and lots of fuses in between (I am not taking any chances, but I am enjoying the attempt to build this).
However, I need to support the heavy motor / generator with a bracket. I purchased two 4-inch exhaust U-clamps to hold the motor to the platform, but the brackets have a strong magnetic attraction to the motor. Will this attraction (and the added metal of the bracket) interfere with the motor's electrical generation capabilities?
The motor is a 24volt, 22amp capable of generating a maximum 350 watts, electric scooter motor XyD-6D permanent-magnet motor, 2600rpm. Thanks!
The brackets will have little effect on the generator. They are just being attracted by the stray magnetic field from the permanent field magnets. But few humans are capable of producing 350 watts. 150-200 is likely the best you can do.
You may be better off with a single 12v battery and a 12v regulator. Permanent magnet motors can work as generators, but they're not designed for it, so they're not as efficient.
