I have a small simple 6 V DC motor and I would like to rewind its rotor. The motor has 2 magnets. The rotor has 3 poles to wind. Normally each part has 169 turns of winding with 0.15 mm2 copper wire.

My intention is re-winding those coils, but I would like to know before winding how many turns and what thickness of wire I need. I want to make calculations, however, I don't know anything more than the information above.

  • why are you rewinding the motor? – jsotola Nov 15 '22 at 22:29
  • Are you rewinding the rotor to try to decrease inrush current? There are easier ways to go about that. – vir Nov 15 '22 at 23:35
  • Rewinding a motor and decreasing inrush current are usually two different things. When you explain why you're rewinding the motor, please don't stop at "to reduce inrush current". Please explain _what you're trying to achieve with the assembly_. – TimWescott Nov 16 '22 at 02:20
  • You can decrease stall current by increasing the number of turns, but it will also reduce speed and power output. Is that acceptable? – Bruce Abbott Nov 16 '22 at 05:06

Rather than rewinding the motor, consider using a current limiter. This can be constructed from two transistors and two resistors.
