START CAP Meaning and
Definition
-
A start capacitor, also commonly referred to as a start cap, is an essential electrical component used in various types of electric motors, particularly in single-phase induction motors. It is designed to provide an initial boost of power during the motor's startup phase, enabling it to overcome high starting currents and initiate rotation.
The start capacitor is connected in series with the motor's start winding and acts as a temporary power source. It stores electrical energy in the form of an electrical charge when the motor is off. When the motor is switched on, the start capacitor releases this stored energy, providing a surge in voltage to the start winding, which creates a rotating magnetic field necessary for motor rotation.
Typically, a start capacitor has a higher capacitance compared to a run capacitor, allowing it to deliver a greater burst of power for a shorter period. This higher capacitance enables the motor to generate sufficient torque during startup, overcoming the inertia and mechanical resistance faced during initial rotation.
Start capacitors are usually designed to be disconnected automatically from the motor circuit once the motor reaches a certain speed or after a short time interval to prevent damage to the windings. They are widely used in a variety of applications, ranging from small household appliances to larger industrial machinery.
In summary, a start capacitor is an electrical component used in electric motors to assist with their starting process by providing a temporary surge of power, allowing the motor to overcome high starting currents and initiate rotation.

Etymology of START CAP
The word "start cap" is a shortened form of the term "starting capacitor". The etymology of the term "capacitor" dates back to the 19th century and is derived from the Latin word "capacitās", meaning "capacity" or "ability to contain". In the context of electrical components, a capacitor is a device that stores and releases electrical energy.
The addition of the word "start" to "capacitor" refers to its specific use in electrical motors, particularly in single-phase motors. The starting capacitor, also known as a motor-start capacitor or simply a start cap, is a capacitor that is temporarily connected to the motor during its starting phase to provide an extra boost of power. It helps overcome the initial resistance and enables the motor to start rotating smoothly.
