Removing the speed sensor.
Aptly named, the speed sensor monitors the speed of the spinning shaft. Should things get out of hand, the sensor will shut off the motor.
The speed sensor uses inductive pickup to tell the control circuitry how fast the shaft is spinning. Inductive pickup is triggered by ferrous metal passing by in close proximity, causing a current to be induced in the pickup. This is really the same effect used by an electric guitar to pick up the string vibrations.
Blendtec informed us that the Total Blender includes what they call a "hammer-fire" system. The main microprocessor will trigger this system if it detects that the blade stopped spinning. The processor will send a series of strong electric pulses with the intent to free the blades from the obstruction. If that fails, it will shut off the motor to prevent any damage.
