Just noticed a thread on Racechat where someone was saying they blew their brushless motor because the sensor lead was faulty and allowed the motor to over heat?
Not heard that one before. Anyone know if this is possible and does it mean we should be changing or at least checking, sensor leads more often?
"also watch your sensor leads, some are proving faulty and cooking motors.
I had a loose fitting connection on one pin (esc end) and it blew an LRP 13.5 in a GT car, so was not under excess load.
Maybe the noticable sign was the loss of all brakes in the prior heat, and the power surge when coming off power in a previous meeting (brakes had gone soft since that surge)"

Interestingly lately I have had a number of issues, which have been resolved by changing to a nice new sensor lead. Upon installation of the new lead I instantly improved my lap times and the motor came off cooler AND I experienced no more cogging (Which developed when the sensor lead was getting old.)
I brought one of those short muchmore leads, which lasted about 2 runs, and now needs a wiggle(Technical Term) to get it to work. I have now gone to the standard long cable that comes with my new motor... and Its running great . ;D

sensor lead testers will be available from the same person who brought you the amazing wet covers and shock pumps.. first products will be ready in just 10 days
order early to avoid disapointment.. Predicted RRP £10

Having looked a bit deeper into the sensor lead thing it seems it is not uncommon for a faulty sensor lead to cause all sorts of problems from low power to cogging and over heating.
Also sometimes a sudden failure of the motor to work at all or to work intermittently. Seems changing the sensor lead could be something you need to do every so often.

I must admit I have changed a few..they have given me cogging/stutter and interference probs....The wire size and pin connectors arnt really man enough for the abuse. |
