What is a Motor Start Capacitor?
A motor start capacitor is a type of capacitor used in single-phase electric motors to provide the necessary torque to start the motor. These capacitors temporarily boost the motor’s starting power, allowing it to overcome inertia and begin rotating. Once the motor reaches a certain speed, a switch disengages the start capacitor, leaving the run capacitor to sustain operation.
Importance of NGM Motor Start Capacitors
NGM motor start capacitors are well-regarded for their reliability and effectiveness in motor applications. They are designed to handle the intermittent high current required during the startup phase of a motor. Their construction allows them to operate efficiently in demanding environments, contributing to the overall longevity and performance of electric motors.
