The insulation class of a motor refers to a standardized classification system used to specify the thermal capabilities and temperature tolerance of the insulation materials used in the motor’s winding and other components. This classification is essential in determining the safe operating temperature range of the motor under various load conditions. Insulation class information helps …
The Inductor Reactance Calculator is a tool to calculate the Reactance of the Inductor on one click. The reactance of an inductor is a key concept in electrical engineering and is used to describe the opposition that an inductor presents to alternating current (AC) flow. Reactance is a measure of how much the inductor resists …
The Fundamental Frequency Calculator is a tool to calculate the Fundamental Frequency of a rotating system. The fundamental frequency of rotation is a term used in physics and engineering to describe the lowest frequency at which a rotating object or system oscillates or vibrates. It signifies the rate at which a rotating system completes one …
Reactance of a Capacitor Calculator The reactance of a capacitor can be calculated using the following formula: Xc = 1 / (2 * π * f * C) Where: Xc is the reactance of the capacitor in ohms (Ω). π (pi) is a mathematical constant approximately equal to 3.14159. f is the frequency of the …
Eddy current losses, also known as “core losses” or “iron losses,” are a type of energy loss that occurs in the core of electrical machines, including three-phase induction motors. These losses are associated with the generation of circulating currents, known as eddy currents, within the core material due to varying magnetic fields. In a three-phase …
IDMT Relay Curve Formula Inverse Definite Minimum Time (IDMT) relays are used in protection systems to detect and respond to overcurrent conditions in electrical networks. The IDMT relay curve describes the relationship between the fault current magnitude and the time it takes for the relay to operate. The curve is typically characterized by its slope …
When capacitors are connected in series, their total or equivalent capacitance is not simply the sum of their individual capacitances. Instead, it is calculated using the reciprocal of the sum of the reciprocals of the individual capacitances.
When capacitors are connected in parallel, their equivalent capacitance is simply the sum of their individual capacitances.
The Capacitance Calculator calculates the Capacitance of a Parallel Plate Capacitor. The capacitance of a parallel plate capacitor is given by the formula: C = ε * A / d Where: C is the capacitance of the capacitor (measured in Farads, F) ε is the permittivity of the dielectric material between the plates (measured in …
