The Magnetic powder clutches and brakes of Sunrise Group, which use magnetic iron powder for transmitting torque, offer advantages such as a smooth fluid clutch and high efficiency upon coupling of the friction plate clutches. Sunrise Group is one of the leader brands of magnetic particle clutches and magnetic particle brakes in China. The magnetic particle clutch and brakes are now indispensable for tension control as actuators for winding and unwinding long materials such as paper, thread, electric wire, various sheets, and tape. They are also suitable for buffer startup, power absorption, and overload safety devices (torque limiter).

Micro magnetic particle brake structure and Feature

1. Continuous slip operation

The powder enables continuous slip on the working surface as well as stable transmission torque regardless of the slip rotation speed.

However, the powder must be used within the permissible continuous heat dissipation.

2. Stable torque

Due to the shape of the operating surface and powder leakage prevention structure, the powder keeps functioning normally and therefore stable torque can be reproduced

3. Smooth connection and drive

With almost equal coefficients of static and dynamic friction, load-based acceleration/ deceleration can be obtained without shock at the time of complete connection

Magnetic particle Brake Feature

Easy control over a wide range

Transmission torque changes continuously in response to changes in the exciting current, and so can be easily controlled over a wide range.

Continuous slip operation

The powder enables continuous slip on the working surface as well as stable transmission torque regardless of the slip rotation speed.

Stable torque

Due to the shape of the operating surface and powder leakage prevention structure, the distribution of powder can be kept uniform and stable torque can be reproduced even if the current is repeatedly turned on and off.

Large heat capacity

The products using powder have excellent heat resistance and an ideal cooling structure, and so can be used even in harsh continuous slip operation.

Smooth connection and drive

With almost equal coefficients of static and dynamic friction, load-based acceleration/ deceleration can be obtained without shock at the time of complete connection.

Maintenance-free

Competitive advantage products will give you an edge over your competitors

Magnetic Particle Brake Mounting

(1) Fasten the fitting part of the mounting flange to the mounting plate and fix it.

(2) Always use an elastic coupling to connect the brake shaft and load shaft, and set the concentricity, perpendicularity, etc. of the shafts at this time within the allowable value of the elastic coupling to be used.

(3) When mounting a pulley or the like, ensure it is within the range of allowable shaft load.

(4) The heat dissipation area of the mounting plate should be at least 350cm².

Magnetic particle Brake Allowable connection workload

When starting or braking loads with inertia with the clutch or brake, the powder and working surface slip and generate frictional heat.

This heat generation raises the temperature of each part of the clutch/brake as well as the powder itself. If the heat generation is excessive, the temperature of the friction part rises abnormally. To prevent this problem, an allowable connection workload is determined for each model. The clutch/brake should, therefore, be used within this range.
