Proportional Magnets

Proportional magnets are used in a variety of applications where precise control of the flow of liquid or gaseous media is required.

In both sliding and seat valves

Proportional solenoid valves are ideal for use in controlled or regulated hydraulic applications, as they provide control over pressure and flow rate.

FAQs

A proportional electromagnet is an electric lifting magnet whose magnetic force is proportional to the current flowing through it. This means that as the current increases, so does the magnetic force, and vice versa. By designing the geometric shape of the transition from the magnetic field-carrying housing to the movable armature, the force acting on the armature is kept almost constant over the working stroke with constant current.
If this armature works against a linear spring, a force equilibrium is established depending on the armature position and the current applied.

Proportional electromagnets are often used in applications where precise control or regulation of fluids is needed.

When electrical current is applied, a magnetic field is created. This magnetic field attracts the piston, causing it to move. The amount by which the piston moves is proportional to the applied current strength.

Proportional magnets are more versatile than normal magnets. They can be used to create weaker or stronger magnetic fields, depending on how they are charged. In addition, they can be used to create a wider variety of shapes and sizes for the magnetic field.

Proportional magnets are used in various applications where precise control of force or movement is required.

Some common applications include:

Construction Industry or Agriculture:

Control of hydraulic control valves in industrial applications such as excavators, tractors, or concrete pumps.

Medical Technology:

Proportional magnets are used for precise control of operating tables or dental chairs.

Energy Technology:

In the field of renewable energies, proportional magnets are used for the control of solar mirrors.

Aerospace Industry:

Proportional magnets are used in the aerospace industry in various applications, such as in hydraulic flight control systems or landing gear systems.

The right proportional magnet depends on the specific requirements and applications. There are various types of proportional magnets that differ in size, performance, sensitivity, linearity, and other factors.
When selecting the right proportional magnet, the following factors should be considered:

  • Performance: The proportional magnet should be capable of generating the required force or movement for the application.
  • Linearity: The magnetic field strength should be proportional to the applied electrical energy to ensure accurate control.
  • Sensitivity: The sensitivity of the magnet should match the requirement to translate small changes in the input signal into corresponding changes in output force.
  • Environment: The proportional magnet should match the environmental conditions, including temperature, humidity, vibration, and other factors.
  • Cost: The proportional magnet should be within the budget for the application.

If a proportional magnet is not working, you can take the following steps to troubleshoot:
Check the power supply and power source to ensure that the magnet is receiving the correct voltage.
Check the connections and ensure that they are correctly connected.
Check the magnet’s input signal and make sure it is within the correct range.
Ensure that the magnet is operating linearly and has the correct ratio of input to output power.
Check the environment in which the magnet is operating to ensure it meets the magnet’s specifications.
If all else fails, the magnet may be damaged and need to be replaced.

If the proportional magnet does not receive the correct power supply or the power source is not functioning properly, the magnet will not work. A common problem, for example, is an interrupted power supply.

Loose or damaged connections: Loose or damaged connections can cause the magnet not to function properly. It is important to ensure that all connections are properly connected and have not been damaged.

Input signals outside the correct range: An input signal that is too weak or too strong can cause the magnet not to function properly. It is important to ensure that the magnet’s input signal is within the correct range.

Poor linearity: A proportional magnet should generate the correct output force in relation to the input signal. Poor linearity can indicate a damaged or faulty magnet.
