Design, improve, optimise, supply, support.

Sensor Magnets

Eclipse Magnetics understands the needs of sensing or sensor applications where cutting edge magnetic assemblies are key to reducing weight, cost, false triggers and overall improving performance. Sensors are used in a wide range of industries and applications, in particular electronic circuits. Electromagnets and permanent magnets can be used to achieve contactless magnetic sensing applications (minimising wear), ferromagnetic materials can also be applied to pull or shield magnetic fields. Whether the application is for detecting fluid levels, detecting rotor position , measuring distances or speed or angle proximity, triggering switches or security we can help provide you with a contactless magnetic solution.

We can provide magnets for Reed Switches, Hall Effect Devices and Search Coils for sensor triggering applications. We offer methods to improve DoM angle by novel production and 100% inspection. We like to use mutual NDA.

We design to meet requirements of sensor applications for field strength versus distance profiles, temperature variation, slide by, slide through, rotation, magnetic shielding (e.g. vanes), etc. Our magnetic solutions for sensors include initiatives for weight reduction, miniaturisation, improved field pathways, cost reduction and even reduction of rare earth material use. Our China Joint Venture also allows us to supply our solutions with PPAP and C of C. With an unrivalled expertise in designing value adding magnetic solutions Eclipse Magnetics is a trusted partner for reliable long-term contract manufacturing supply. This includes holding stock in UK for guaranteed fast call off supply.

Sensor Magnet Application Examples Include:

  • Magnets for electric motor rotor position
  • Seat belt sensor magnets
  • Fuel level gauge magnets
  • Magnets for safety locks
  • Magnets for engine valve timings
  • Contactless temperature estimation magnets
  • Contactless position sensing magnets
  • Speed sensing magnets
Reed Switch Sensor Magnets

Reed Switch Sensor Magnets

We can look to assist you in matching magnets to Reed Switches. Reed Switches are rated in Ampere-turns which cannot easily be linked to a Gauss or Tesla value (because each electromagnet test coil used for the rating has a specific design). We can work with you to work out the required field strength to trigger the Reed Switch and then we can re-design a magnet to meet your application requirements (so, for example, the Reed Switch can be activated further away).

We can custom design magnets to give specific field strengths at specific positions for nearly any temperature. We can match custom magnets to existing Hall Effect devices and can design magnets to activate Reed Switches.

Direction of Magnetisation (DoM) measurement

Hall Effect Sensor Magnets

These have a Gauss or Tesla value to trigger and release. They are sometimes better than Reed Switches for use in custom applications.Gauss meters use Hall Effect devices to measure magnetic field strengths. We can produce magnets to meet field strengths at specific distances.

Power Generation Solutions

Eclipse Magnetics understands the needs of power generation customers to design commercially viable PM generator solutions that have reduced weight, high power density, compact design, longer service life, reduced cost and higher efficiency.

Whether the application is for magnetically balancing rotors, designing out rare earth magnets using ferrite magnets, increasing power density by miniaturisation, enhanced flux concentration at the poles, designing pancake generators and canister generators, or reducing flux leakage, Eclipse Magnetics will help you achieve your solution.

We can magnetically balance the rotors (as well as mechanically balance the rotors) to give less back emf variation between phases to help simplify the power electronics circuitry. We like to use mutual NDA. We design to meet requirements for pull forces, torques, field strengths, temperature, sensor specifications, etc.

Principle of back emf (voltage) generation

Principle of back emf (voltage) generation

Faraday’s Law for back emf E generation is:-E = - N (dϕ/dt) shown as E = - NA (dB/dt)dϕ/dt is the lines of magnetic flux ϕ cutting through the coil over time t. But ϕ=BA so the magnetic field strength B in the coil changes with time for electricity generation (A is coil hole area). Lenz’s Law gives the minus sign.The back emf is an alternating voltage (a.c.). Rectification and smoothing is needed for d.c.

Examples Magnet Shapes available. We can custom produce magnets to nearly any shape to meet customer requirements. Factors affecting back emf generation. Number of turns – generated voltage is proportional to the number of turns per coil, N.Number of coils – more coils can mean more voltage if connected in correct sense in series (more N overall) but coil position relative to magnet position can introduce phase-shifted a.c. voltages (used for e.g. three phase a.c.).Number of Magnets – If the design can take more magnets then a coil may see more magnets per revolution passing by giving more changes in field per revolution giving a smaller dt hence a higher back emf for the same rotational speed.

But this may introduce electrical phases depending on the design.Magnet strength – a stronger magnetic field gives more field (B) in the coil. This can be achieved by stronger magnet grade or type (e.g. N45 instead of N35, NdFeB instead of Ferrite), flux concentration design, better magnetic pathways (less air gap), etc.Speed – faster rotation or movement means dt decreases resulting in a higher back emf.Losses – no design is 100% efficient - factors such as eddy current losses, heat, stray flux etc reduce efficiency. Use of thinner laminations can lower eddy current losses.Inductance – self inductance and mutual inductance affect magnetic performance.
