Rare Earth Sintered Neodymium Multipole Ring Magnets

Rare Earth Sintered Neodymium Multipole Ring Magnets Radial ring sintered magnet, a neodymium magnet manufactured, and its magnetic fields could be aligned in different directions then “normal” neodymium ring magnets. Under the manufacturing process several different magnetic fields can be created in a single ring, and in several directions. Radial neodymium rings makes it possible to [...]

  • The difference between electromagnet and permanent magnet

The difference between electromagnet and permanent magnet

The difference between electromagnet and permanent magnet Electromagnets (solenoids) is a kind of electromagnetic equipment, which transforms electric energy into magnetic energy, and then transforms magnetic energy into kinetic energy (electric energy → magnetic energy → kinetic energy). First of all, the core is wound with a conductive winding matching its power. Such a coil [...]

  • Why does the bonded NdFeB magnet break after it breaks

Why does the bonded NdFeB magnet break after it breaks?

Why does the bonded NdFeB magnet break after it breaks? The rectangular bonded NdFeB magnet has N and S poles at its ends. If it is broken into left and right, then does its polarity become N and S poles and S pole and N pole? Why does the bonded NdFeB magnet break after [...]

Rotor magnet shaping technologies for permanent magnet electrical machines

Rotor magnet shaping technologies for permanent magnet electrical machines Engine torque ripple is essential for the comfort of vehicle passengers. Large torque ripple may result in a harsh driving experience. Moreover, additional noise and vibration are byproducts of torque ripple. The service life of the machine and attached components can be influenced by severe vibrations. [...]

Magnetic Caculations

Magnetic Caculations - About Rules of Thumb and Quick Calculations 1. How are energy product and magnet strength related? Magnet strength needs to be defined. Magnet strength actually is a measure of total flux in the area of interest. If greater holding strength is desired, then more Br is needed, and since holding force is [...]

  • DRONE MOTOR PERFORMANCE FACTORS

DRONE MOTOR PERFORMANCE FACTORS

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 [...]

  • Orientated Magnets Direction

Orientated Magnets Direction

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 [...]

  • Magnetic Encoder Engine Technology

Magnetic Encoder Engine Technology

Magnetic Encoder Engine Technology An optical encoder uses light (optics) to identify unique positions for the encoder. A magnetic encoder uses the same principle to determine a position as an optical encoder, but it does it using magnetic fields rather than light. With a magnetic encoder, a large magnetized wheel spins over a plate of [...]
