Permanent Magnets Markets and Devices / Applications

Permanent Magnets Markets and Devices / Applications Devices • Electromechanical machines and devices e.g. motors, generators, actuators • Acoustic transducers e.g. speakers,  earphones, ringers • Mechanical force and torque devices e.g.  holding, lifting, clutches • Microwave and ion beam control e.g.  TWT’s, particle accelerators • Conversion of external stimuli to electrical signal e.g. sensors • DC field generation e.g. MRI Markets and Industries • Automotive and transportation • Industrial and commercial • Consumer products • Military and aerospace • Medical Permanent Magnets Markets and Devices Applications Sensors/Encoders Hall Effect Encoder for end of shaft applications.  Available as either absolute or incremental encoders they can provide digital position, analog position, and quadrature speed outputs. Capable of rotational speeds over 20k RPM. Hall IC used for this application uses a diametrically magnetized magnet. Hall Effect through‐shaft encoder.  Requires use of Hall IC capable of off‐axis sensing using multipole bonded magnet. Low cost, speed or position sensors typically seen in automotive applications – Cam position, crank position, engine speed, ABS.  This type  of sensor can be designed for either face or lateral sensing applications and may, in addition to the Hall IC, incorporate a magnet if sensing a metal target or a pole piece if sensing an encoder multipole magnet. What is the best permanent magnet material and process? •It depends; on the weight/space limitations, application operating conditions, operating parameters of the magnetic circuit, annual quantity, device assembly mechanization etc. • Despite have lower flux output bonded magnets can offer advantages over sintered magnets for many applications. • Despite lack of breakthrough in new materials over the last 30 years there are several promising developments in bonded magnets on the horizon. • [...]

PM Motors Outperform Induction Motors

PM Motors Outperform Induction Motors Induction motors are the most common type of AC motors (about 80% of all motors) used today in industrial applications due to their simplicity, rugged construction and relatively low manufacturing cost. However, fuel efficiency of this type of motor is still not sufficiently high. Scientists and experts are try for [...]
