What is magnetic coupling and magnet gear?
Magnetic coupling & gear is non-contact power transmission device by magnetic atraction & repulsion force
You may have a lot of advantage of non-contact powertransmission.
INDEX
Structure and role of magnetic coupling & gear
Structure
Multi-poles structure by alternate magnetized N poles & S poles.
Utilize attraction force between different poles,and repulsion force between same poles to transmit rotation power.
Role
Role of magnetic coupling & gear is to transmit rotation power or transfer rotational motion to linear motion without mechanical contact such as by traditional coupling, gear and ball screw.

Example solutions by magnetic coupling & gear
Magnetic products suit for those who have troubles as below.
1. We want to transmit the rotation through
the partition wall. (No sealing is required.)
[Application] Liquid mixer ( Sealed container )
Recommended for eliminating sealing and improving sealing!
[Movie] Transmission through partition wall (Water container)
2. We are in trouble of frequent parts
mount-dismount & maintanance.
[Application] Food mixing machine
Magnetic coupling promise you easy replacement & maintanance of stirring blade!
Recommended for food machine required frequent cleaning, as well as frequent attachment replacing required machine.
[Movie] Transmission through partition wall (Mixing machine)
3. We want to reduce noise & vibration.
[Application] Transportation equipment, conveyor
You may eliminate micro-step vibration or driving noise caused by mechanical gears.Recommended for presision devices handling due to less influence of vibration, no wear-out of gear.
Frequent queries for Magnetic couplings & gears
Q1.Would magnetic force be devreased?
A1. Decreased maximum 0.1% per year.
Q2. Is there any influence to sorrounding devices
by magnetic flux leakage?
A2. Almost no influece if apart 50mm from magnet .
Please feel free to contact us for magnetic field analysis service.
Q3.What is maximum operating environment temperature?
A3.Maximum torque described in website is under room temparature.
Torque decrease step by step in accordance with temparature increase.
Please contact us in case of usage under high temparature.
Q4. Is there any points of attention for assembling?
A4. Here is the points of attention for assembling.
Please fix magnetic products onto the shaft after placing the spacer which is non-magnetic, high stiffness, and high sliding nature.
Q5.Does the torque change according to the gap between
both hubs at assembling?
A5.Transmittable torque will decreased when the air-gap is wider, while increased when it is narrower.
Please confirm the maximum torque for every gap distance by the chart.
＊You can use the products as torque limitter since maximum torque (slip torque) is adjustable.
※Above data is example of CP series.
