ITB Throttle Bodies with Integrated Stepper Motor

Within a speed control system, a throttle body is used to regulate the supply of the gas/air mixture and thus the speed and power of a gas engine.

MOTORTECH ITB throttle bodies are equipped with an integrated stepper motor, which eliminates the use for an external actuator. The stepper motor is extremely precisely actuated by the VariStep3 stepper motor driver in combination with the SC100 speed controller.

Throttle Bodies with Integrated Stepper Motor
