Ohm’s Law and Its Application in FIRGELLI Electric Actuators

Ohm’s law, a fundamental principle in electronics and electrical engineering, is crucial in understanding and optimizing the performance of FIRGELLI Electric  Actuators. These actuators, often employed in automation systems, robotics, and other applications requiring precise motion control, operate on electrical principles that are well-described by Ohm’s law.

The Basics of Ohm’s Law

Ohm’s law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points. It is expressed mathematically as V = I x R, where:

• $V$ is voltage
• $I$ is current
• $R$ is resistance

Application to Actuators and Motors

When powering a FIRGELLI Electric Linear Actuator, understanding Ohm’s law aids in choosing the appropriate power supply, managing heat dissipation, and ensuring efficient operation. The actuator’s motor has inherent resistance, and by applying Ohm’s law, users can predict the current draw under various loads, contributing to efficient power management and performance optimization.

Implications for Performance and Safety

Knowing the relationship between voltage, current, and resistance aids in safeguarding the actuator from overcurrent scenarios, potentially resulting from low resistance or high voltage, ensuring the durability and safety of the device. By adhering to Ohm’s law, the risk of overheating and other electrical failures is minimized, ensuring consistent performance and extending the lifespan of the actuator.

Three-Phase Power and Ohm’s Law

Three-phase power is commonly used in industrial applications and large motors due to its ability to transmit more power with fewer wires and higher efficiency. In the context of Ohm’s Law, the formulas are modified to accommodate the complexity of three-phase systems, which are essential for running large FIRGELLI electric linear actuators efficiently.

Calculating Current in Three-Phase Power

In a three-phase power system, the formula to calculate the current is given by:

Current (I) = Power (P) divided by  (Voltage (V)  x Power Factor (PF)  x 1.732)

Here,

• Power (P): The total power consumed by the system.
• Power Factor (PF): It is the ratio of real power flowing to the load, to the apparent power in the circuit. It tells us how effectively electrical power is being converted into useful work output.
• Voltage (V): The voltage supplied to the circuit.
• √3 (1.732): A constant derived from the three-phase power system.
