[EVDL] How To Burn Up Your DC Motor
Maybe this is common knowledge for this group, but I recently learned how to burn up my motor.
I was returning home, thinking about the prospect of working on the car and bumping the accelerator. I was working under the dash recently, on the heater core. If it were in gear and on, who would win: the motor or the parking brake? Some of you see where this is headed. I parked the car in the garage, set the brake and pressed the accelerator for at least 2 seconds, probably 4 or 5 seconds. The battery delivered 25A during this. The brake won, I turned everything off and went inside. The next day, as the car began to roll, there was a tick-tick sound. I'd overheated the commutators and lifted 4 bars. A LOT of motor amps had heated it when it wasn't turning.
The Zilla has stall protection; my Soliton apparently does not.
Lesson learned. :-\
BTW, Steve and Audrey from Green Shed Conversions drove up from Florida on short notice and brought a spare motor so I could show the car for Earth Day. Wow! Kudos and a big thank you!
