Speed Sensor
This DC motor uses an optical tachometer to provide real-time RPM feedback to the control logic. If the sensor is obstructed by grease or suffers an internal diode failure, the feedback loop is broken, causing the control board to hunt for the correct speed by varying the voltage. Replacing the sensor restores the timing signal required for stable motor operation.

Motor Control Board
The control board processes the user-selected speed and manages the pulse-width modulation (PWM) to the motor. If the logic circuit or capacitors responsible for smoothing the DC output fail, the board will deliver inconsistent power regardless of the sensor feedback. This results in erratic motor pulses and the inability to maintain a constant rotational velocity.

Speed Control Plate
The speed selector lever interfaces with a carbon-track potentiometer that sets the reference voltage for the control board. Physical wear on the resistive track or debris ingress causes signal 'jitter,' which the motor control board interprets as a rapidly changing speed command, causing the motor to mimic the unstable input signal.
