Accelerometers and Gyroscopes
Electron Energy magnets and assemblies are used in sophisticated, performance-critical components of advanced technology systems, such as accelerometers and gyroscopes.
Accelerometers and Gyroscopes are inertial devices used primarily in aircraft, marine vessels and spacecraft navigation, control systems and down hole drilling.
Samarium cobalt magnets are a critical part of the spinning flywheel in miniature two-axis dynamically tuned gyroscopes. The magnet ring creates a magnetic field interacting with torquing coils to allow control of the flywheel. The gyro measures the rotation of the earth accurate enough to find north for a wide variety of navigation tasks.
Temperature compensated SmCo magnets provide precision control and stability for accelerometers and gyroscopes. Temperature coefficients of residual induction for magnets used in the applications can be controlled to better than 0.001% change in Br per degree C or 10 parts per million.
