8s ESC on 6s Motor?

[skids929]

Researching motor and ESC combos. Got curious on this question...Is it possible to run an 8s (160a) ESC with a regular 6S Max motor?

For awhile.. haha. Very closely monitor temps.. it will get hot quickly ...

Unless you're actually running 8s, an 8s ESC is over-built for a 6s motor. But running 6s will keep the ESC cool and it might even be a bit faster if the motor has more power than the old ESC was supplying.

Basic rule, motor determines everything. You run the voltage (or less) that your motor will handle. You can run higher, but you have to know the motor, how it was built, what RPM it's rated for, and what voltage it can handle. For example, a 4600kv is a 2S motor (most motors are rated for 50k RPM). But a castle 1406 4600 is rated for 100k RPM, so you can run 3s without expecting it to explode. It will get hot, though.

Yes, that’s why I said “for awhile... haha” meaning that if you continuously run 8s through the 6s motor you’ll most likely explode it. But if you closely monitor your temps you’ll likely get some good use out of It still. Myself and many others have used the factory 2050kv on 8s for short term basis or just low Demand speed runs with small tires.

Also, to clarify.. running 6s on an 8s esc with a 6s motor SHOULD BE completely legit. But stepping up to 8s for that 6s motor you will have to be careful.

Does a max6 have an option for 7s?????????

The issue with using higher than rated voltage on ANY motor is exceeding the RPMs that a motor is built to handle. Most average motors are good for 50k RPMs. Push higher than that for extended periods and you can expect the motor to die quickly. Might be from heat melting things. Heat also reduced magnet strength. Rotor wraps also can fall apart. Bearings not designed for higher speeds can fail. Plenty of ways a motor can be destroyed.
