AS 3919 Innovative Applications of Bistable Rotary Solenoids

About the bistable rotary solenoid ?

The Bistable Rotary Solenoid is protected by a solid carbon steel housing. The insulation class is IP50; an increase to IP65 is possible using additional housing. The nominal voltage is 12, 18 or 24 Volt; the torque is 1 Ncm to 1 Nm. The end positions are fixed with holding torque of up to 1 Nm. Depending on the application, a rotation angle of up to 180° can be realized. Hall sensors can be used as an option to check whether the magnet has reached the start or end position.

Working Principle

The bistable rotary solenoids are extremely fast switching rotating magnets for the optimum performance of demanding sorting and actuating tasks. With a speed of less than 10 ms, letters, banknotes or parcels can be sorted extremely fast and in the correct position. The high rotational speed is achieved by reversing the polarity of the rotary solenoid. The safe end position is realized by a permanent magnet. The so called "Polarised Rotary Solenoids" (PDM) are used in automation and logistcs as a cost-saving alternative to pneumatics or motor solutions due to their energy efficiency.

Selecting the Right Rotary Solenoid

When choosing a rotary solenoid for a specific application, several factors must be considered to ensure optimal performance and reliability. Some of these factors include:

Operating Voltage and Current: It is crucial to select a solenoid with an appropriate operating voltage and current for your application to prevent overheating and ensure proper functioning.

Rotational Angle: Depending on the application, the required rotational angle of the solenoid may vary. Ensure that the solenoid you choose can provide the necessary angular displacement.

Torque Requirements: The solenoid must generate enough torque to perform the desired task. Consider the torque requirements of your application when selecting a rotary solenoid.

Operating Environment: The environment in which the solenoid will be operating can affect its performance and lifespan. Factors such as temperature, humidity, and the presence of corrosive or abrasive substances should be considered when selecting a solenoid.

Size and Weight Constraints: In some applications, space and weight limitations may dictate the choice of solenoid. Be sure to select a solenoid that fits within the constraints of your application.

What are Rotary Solenoids used for?

Rotary solenoids were originally developed for use in defense in the past decade, but nowadays are often found in industrial machinery such as lasers and shutters, banking counting machine as they're more robust than other types of solenoids. Typically, rotary solenoids are used where space is limited and when long life is required (e.g., laser shutters). Their energized rotation (direction) is characterized as either clockwise or counterclockwise when viewed from the armature flange end. Most products have a spring return to bring the armature back to the home position when power is removed.
