Permanent Magnet Stability The ability of a permanent magnet to support an external magnetic field results from small magnetic domains “locked” in position by crystal anisotropy within the magnet material. Once established by initial magnetization, these positions are held until acted upon by forces exceeding those that lock the domains. The energy required to disturb [...]
DRONE MOTOR PERFORMANCE FACTORS / quadcopter motor factors KV - Velocity Constant Theoreticly KV represents the speed at which the motor rotates for every volt applied to the motor. For example if a motor is 2300kv with a 3S quadcopter battery motor applied to its ends then the motor will spin at 2600x12.60 =32,760 rpm [...]
Plastic Bonded Pressed Magnets / Plastic Bonded Magnets Plastic bonded pressed magnets are the result of the union between thermoplastic binders and permanent magnet powders, and can be made in isotropic or anisotropic qualities. Pressed magnets are magnetic products manufactured with high precision and tailored for each application. Type of material Magnetic powders: ferrite or [...]
12 Things You Didn’t Know About Rare Earth Metals 1 They’re Not That Rare. Most of the rare earth metals really aren’t that rare. Cerium (Ce) is the most abundant rare earth metal, followed by Lanthanum (La), and then Neodymium (Nd). Cerium, Lanthanum and Neodymium are all more abundant than Lead (Pb). 2 It’s actually [...]
Orientated Magnets Direction, Direction of orientation For ‘Orientated Magnets Direction / direction of orientation’ it is understood the position of the magnetic cristals in a specific direction. In the correct direction, the magnet reaches its magnetic values and thus, should be magnetized in this direction. The direction of orientation is achieved by exposing the magnetic [...]
Bonded Magnet Materials and Processing Options Bonded magnets are an important but often overlooked group of products that magnetic circuit and device designers should consider when choosing the optimum permanent magnet type for their specific application need. In their most basic form bonded magnets consist of two components; a hard magnetic powder and a non-magnetic [...]
MPCO Magnets for TMR Angle Sensors MPCO Magnets for Tunnel Magneto-Resistance (TMR) Angle Sensors distributes a magnetic field to reduce angular errors. These magnets offer high-reliability and a magnetization to minimize the error of angle. The magnets for TMR angular sensors feature a high-robustness against the setting area between the magnet and TMR angle sensor. [...]
Applications for Magnetic Sensors Magnetic sensors are used in many industrial applications for contactless current sensing, linear and angular position, and rotation sensing. magnetic sensors are designed to provide superior performance in all of these applications. Magnetic sensor products are based on its unique MLU-patented technology. In contrast to Hall devices that generally have low [...]
TMR Sensor Magnets TMR sensor is an epoch-making magnetoresistance effect sensor which has been applied to industrial application in recent years. TMR sensor has a much higher resistance change rate compared to AMR and GMR sensor, thus obtained many merits include low cost and power consumption, high response frequency and sensitivity. SDM has also collected [...]
All About Magnetism and How it Works From your clothes to your desk, every bit of matter is made of tiny particles called atoms. Atoms have negatively charged electrons that spin around them. Most of the time, the electrons spin in random directions. When the electrons all spin in the same direction, though, they create [...]
Reed Switches vs. Magnetoresistive Sensors In a previous post we took a look at magnetic field sensors vs inductive proximity sensors for robot grippers. In this post I am going to dive a little deeper into magnetic field sensors and compare two technologies: reed switches, and magnetoresistive sensors (GMR). Reed Switches The simplest magnetic field [...]
