well, I did fry many gear motors (do’t ask me how many, but I do have spare gear heads, just in case! :)).
1Google MOV 20mm 30V – Kartman 6 hours ago. Do you know of a nice noob level h bridge brand I could use? – TheCodeNovice 6 hours ago Would it over heat with out running the motor? I do not think that worm gear motor I am using will run close close to the rated 13A that is why I thought I could slide by without it. Do you have a link of MOV so I know what I am looking for? – TheCodeNovice 7 hours ago My first impression is that it is not newbie proof, because over temperature and over current can fry the driver! 🙂 – tlfong01 7 hours ago Just now I skimmed the Pololu motor driver you are considering, to get a rough idea of your requirements: (1) Pololu G2 High-Power Motor Driver 24v13 (6.5V to 40V, cont 13 A without heat sink, no over-temperature, over current shut-off) /product/2992. Something like a 20mm 30V device. – Kartman 7 hours ago 1What is the frequency of the pwm? Generally I’d put a varistor (MOV) across the motor terminals as close to the motor as possible. Thanks in advance! mosfet motor h-bridge induction-motor ShareCite EditFollowFlagasked 7 hours ago TheCodeNovice 13355 bronze badges Help a poor ME sticking his toe in the water of electronics! Do I need to spend more money on someting like the following? I would think a motor driver board would know it would be dealing with inductive loads and protect against this but maybe I am wrong. My most recent board was working, next thing you know the ERR LED light is on and the manual says “ERR LED Indicator – Error LED Indicator, it will illuminate when fault detected in on board MOSFET driver.” This makes me suspect not my wiring but something else and possibly not protecting the components. 
I have been using the following: driver 1 and driver 2 to control the motor but they keep failing and at random times. I am a ME by trade but I remembered a smidgen about inductive loads and back EMF wreaking havoc on components. I have blown 4 h bridge motor drivers thus far and while I have been trying to keep my project price tag low I may need to step up in quality but I want to make sure something else may be going wrong. I am looking for some consultation about controlling a 24VDC worm gear moto.
