A motor controller for use on a treadmill to prohibit the treadmill from operating at a high speed immediately upon energization. The controller uses solid state circuitry in a motor speed circuit with a speed setting potentiometer set by the user. The system is adapted so as upon energization a minimum speed is initially achieved. The results are obtained with the interaction of a buffer circuit, solid state circuitry, and an SCR motor speed control circuit.
