Electromagnetic Clutches
Single-face electromagnetic clutches connect a drive at the flick of a switch. They’re the most common type, used in everything from office machines and conveyors to packaging, printing and food processing.
- 0.25 – 2,000 Nmtorque range
- zerobacklash armatures
- fastresponse for high cycling
- 100%torque transfer once engaged

How it works
How It Works
Engaging
Power to the coil turns it into an electromagnet. The magnetic flux crosses a small air gap and pulls the armature hard against the friction face, so the two turn together – electrically switched, but transmitting torque mechanically.
Releasing
Switch the power off and springs pull the armature back, opening a small air gap so the parts turn freely. Cycling is just switching the coil on and off; once engaged there is no slip, so torque transfer is 100% efficient.
Why Ogura clutches
Fast, Quiet and Long-Lived
Zero Backlash
The armature is mounted on a leaf spring – no backlash and no rattle.
Automatic Air Gap
On some models the gap adjusts itself as the clutch wears, so engagement time stays the same.
Fast Response
Single friction plate design for high-cycle work.
Quiet
Smooth engagement without chatter; quiet armature options.
How to choose
Choosing a Clutch
Torque
Size to the torque at the shaft, with a safety margin for starting loads.
Cycle Rate
High cycle rates need a fast-response armature and enough heat capacity.
Mounting
Shaft or flange mounted, with pulley, gear or coupling output.
Voltage
Standard coils are 24 V DC; others are available.
