Motor Capacitors: Enhance the Efficiency and Reliability of AC Motors

alfatec GmbH & Co. KG offers a comprehensive selection of high-quality motor capacitors, which are essential components for optimizing the performance and service life of alternating current (AC) motors. Our product range covers various industrial and commercial applications, ensuring reliable operation and improved efficiency. We provide a wide variety of run capacitors and start capacitors. There are two main types of AC motor capacitors:

  • Start capacitors (start capacitor): These are used to kick-start the motor. They provide a temporary boost in power, enabling the motor to start with sufficient torque.
  • Running capacitors (running capacitor): These capacitors are active during normal motor operation and support the motor's performance and efficiency.
