Hello,
I have a 24V set up with a PWM ECM in my kids jeep powerwheels. I have run a variety of motors in the past. Stock to HPI 550's to the Titan 775's. They have all ran fine until they went up in smoke or slowed down from use. I have now made adapters to run Dewalt 802's. They are DeWalt 396505-21SV. These are big motors with replaceable brushes.
The problem I am encountering is that they have very little power. They spin up to speed then slow down. They won't move the power wheels with a kid in them. The only thing I can think of is they need a capacitor. The Titan's have a small cap soldered onto them that I have noticed. Are these big Dewalts drawing too much and the pulsing of the ECM is not enough to run them without a cap?
Do these need a capacitor too? How big and what size if so? Is my theory here sound correct or is there possibly something else I am missing?
