Motor Start Capacitor
Understanding Motor Start Capacitors
Motor start capacitors are essential components in the startup phase of single-phase AC induction motors. These capacitors provide the necessary torque to start the motor by temporarily storing an electrical charge and releasing it to boost the current through the start windings. Once the rotor reaches about 75% of its maximum speed, the motor start capacitor is disconnected from the circuit, usually by a centrifugal switch. This feature makes motor start capacitors crucial for applications requiring rapid cycling on and off. Their capacitance values typically exceed 70 µF, and they come in various voltage ratings tailored to specific applications.
Multiple Applications of Motor Starting Capacitors
Motor start capacitors are predominantly used in single-phase AC induction motors, which are common in domestic appliances where a single-phase power supply is more practical than a three-phase supply. Despite being less efficient—2 to 4 times less so compared to three-phase motors—single-phase motors are sufficient for less powerful applications. Typical devices that utilize motor start capacitors include power tools, washing machines, tumble dryers, dishwashers, vacuum cleaners, air conditioners, and compressors. These capacitors are vital for ensuring that these appliances start efficiently and perform reliably.
