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 [...]

Drone Motor Magnets Drone is an unmanned air vehicle which steered by radio equipment or pre-installed control program. Drone Motor Magnets - The world’s first drone was born in the 1920s in order to fulfil the need of war. With the advancement of technology, the performance of drone continued to be improved and widely used [...]
WIND TURBINE & GENERATOR MAGNETS wind turbine generator magnets - Wind power generation is one of the important applications of neodymium magnets. At present, the installed capacity of wind power in the world has exceeded 200 million kWh. However, due to excessive expansion and the sharp rise in rare earth raw materials and other factors, [...]
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 [...]
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 [...]
