Motor run capacitors maintain a charge and stay energized while a motor is operating. They improve a motor's running performance by continuously providing additional torque, whereas start capacitors exit the circuit once the motor reaches its operating speed. When replacing a run capacitor, it's important to match the shape (round, oval, or rectangle) and the microfarad rating, voltage, and dimensions of the original capacitor. Run capacitors are typically used with medium-to-high torque applications required for air conditioners, auger drives, compressors, and conveyors.
