Study Notes
Hydraulic System Pressure
- Pressure in a hydraulic system is equivalent to force per unit area, similar to how pressure is measured in other contexts.
Resistance and Current Flow
- Resistance in a circuit directly affects current flow, acting as an obstacle.
- Higher resistance leads to lower current, and vice versa.
Electrical Analogy to Fluid Power Volume
- Current in electrical systems is analogous to volume flow rate in fluid power systems.
- This means that the volume of fluid moving through a hydraulic system is analogous to the amount of electrical charge flowing through a circuit.
Direct Current
- Direct current (DC) provides a continuous flow of electrons in one direction.
- This is in contrast to alternating current (AC), which changes direction periodically.
Electrical Resistance Term
- The term for the restriction to current flow in a circuit is resistance.
- It is measured in ohms (Ω).
Voltage and High Resistance
- When voltage is applied to a circuit with high resistance, the current flow will be low.
- This is because the resistance restricts the flow of electrical charge.
Ohm's Law
- Ohm's Law describes the relationship between voltage, current, and resistance.
- It states that voltage (V) is directly proportional to current (I) and resistance (R).
- The formula is V = I x R.
Stationary Electric Motor Voltage Range
- Stationary electric motors in hydraulic systems typically operate within a voltage range of 24-48 volts (DC).
- The specific voltage used depends on the motor's design and the application.
