RC Lawn Mower/Motor Control

Victor 883

• Original MOSFET: IRL 2203N
  • TO-220 package
  • Digikey Part

Repair

• Justin's MOSFET: 07N60C3
  • Vds = 650V
  • Id = 7.3A

Plan: Figure out which legs of the MOSFETS are connected to the output pins that go to the motors. Test those with a multimeter to see if the output is what is expected.

Custom Build MC

• MOSFETS
  • IRL 2203N 13 for $24.31

• $50+ Motor Controller
• $40 Accepts PWM Input
• $20 Scooter Motor Controller
  • this can run in reverse, and has a hold position.
  • this is controlled by voltage rather than PWM
