Our Line of Bi-Stable and Self-Restoring Rotary Solenoids
Capacity for Volume: Since we are vertically integrated, we have the ability to adjust production to accommodate prototype quantities to tens of thousands of units. Brandstrom is your one-stop rotary solenoid solution!
For standard off-the-shelf applications, Brandstrom manufactures a comprehensive line of bi-stable, self-restoring (momentary) and self-restoring 3 position solenoids. This product selector lets you view the Brandstrom product with the options you want.
About Rotary Magnetic Solenoids
Rotary solenoids are devices which convert electrical energy into rotational mechanical energy. A magnetic field is created when electricity flows through a coil of wire (solenoid) inside the device. The orthogonal component of the magnetic field relative to the poles of an internal drive magnet is what creates the rotational force (torque) used to move the shaft of the device.
Miniature rotary solenoids can be used as rotary actuators for lightweight mechanical linkages.
Rotary Solenoid Configurations
All rotary solenoids manufactured by Brandstrom Instruments operate based on the principle of a spring-free, electromagnetic system. Mechanical and electrical operating parameters can differ depending upon application, but all rotary solenoids conform to one of the three configurations described below:
Click & release the power button to test.
When the Bi-stable solenoid is energized with a pulse, the shutter rotates from the start position to the secondary position. It will remain magnetically latched in the secondary position until an opposite polarity pulse is applied, returning the shutter to its starting position
Click & hold the power button to test.
The solenoid is magnetically latched in its home position until it is energized, then the shutter will rotate to the secondary position and remain there until power is removed, allowing it to return to the home position.
Self-Restoring 3 Position Solenoid
Click & hold the positive or negative power buttons to test.
The solenoid is magnetically balanced in a center position until it is energized; then the shutter rotates to position 2 and remains there until power is removed, returning the shutter to the center position. A reverse polarity pulse is applied to rotate the shutter in the opposite direction to position 3 where it will remain until power is removed, returning the shutter to the center position once again.
