Hello,
I'm currently constructing an electric bicycle using a 500w 24v motor, 2X24v 7ah batteries (maybe 4 later on). I bought a 24v 30a dimmer switch to use as a "throttle". During the intitial test (on a table, not on the bike!) It worked absolutely fine for 2 minutes, but then began to smoke and gave out completely leaving the motor to run at full power. i purchased the same dimmer switch again, but can anyone think of a reason why it happened and how i can prevent the circuit from ruining the new switch?
Here is a list of links to the parts I'm using:

EDIT: i have seen posts saying this circuit would not work because the motor is not controlled by voltage, but by frquency. regardless, i don't see why this would cause the switch to smoke and give out.
