Permanent Magnet Hysteresis Brakes and Clutch

OGURA offers a variety of sizes and configurations for hysteresis brakes and clutches.

Permanent Magnet Hysteresis Brakes and Clutches are ideal solutions for precise torque load control, maintaining low friction levels and eliminating the need for an external electrical connection. This technology leverages the hysteresis principle to provide smooth motion, immediate response, and minimal wear levels.

Operating Principle

These brakes and clutches function based on permanent magnets that generate a magnetic field, exerting a hysteresis force on the rotor. When the rotor spins within the magnetic field, a stable and uniform resistance torque is created, enabling precise control over speed or system tension. Unlike electromagnetic brakes, this system does not require an external power source, making it more reliable and energy-efficient.

Advantages of Using These Brakes and Clutches

• Precise Torque Control – Independent of rotor speed, ensuring high consistency.
• No Mechanical Wear – Since there is no direct contact between components, mechanical wear is prevented, significantly increasing product lifespan.
• Quiet and Vibration-Free Operation – Ideal for applications requiring smooth and precise motion.
• High Reliability – No need for electrical connections or sensitive components, ensuring stable performance over time.
• Minimal Maintenance – The absence of friction and wear significantly reduces the need for regular servicing.

Applications

Permanent Magnet Hysteresis Brakes and Clutches are suitable for a wide range of industries and applications, including:

• Electronics Industry – Motor testing, cable quality testing, and tension control for delicate wires.
• Industrial Printing Systems – Controlling the speed of paper rollers to prevent tearing or wrinkling.
• Automotive Industry – Testing systems for engines and rotating assemblies.
• Medical Equipment – Devices requiring precise torque control, such as adjustment mechanisms for delicate rotary instruments.
• Automated Production Lines – Torque control for semi-automatic and automatic equipment to enhance accuracy and quality.

• HB Series – (Electromagnetic Hysteresis Brake)
  Electrically controlled hysteresis brakes with an exceptionally precise hysteresis mechanism, allowing control over variable loads while maintaining stable torque even at high speeds.
  How It Works?
  In this series, the rotor and permanent magnet do not come into direct contact but instead create a varying magnetic field that induces the hysteresis effect. As the rotor spins within the magnetic field, internal eddy currents generate a stable and repeatable resistance torque. Adjusting the position of the magnets or field strength allows for torque regulation according to application requirements, making this series ideal for tension control, precise torque testing, and sensitive medical applications.
