DC brushless motor operation, not only need sufficient power, but also need a high magnetic amount, only in the premise of sufficient magnetism, in order to run efficiently, then DC brushless motor to what magnetization requirements?Vacuz give you an introduction to it! Hope it can help everyone!

motor paso a paso

1. In terms of magnetic parameters, different gap magnetic field distribution shapes are required. For example, for pure output-driven DC brushless motors, their performance requires a high output power and efficiency. Therefore, the internal gap magnetic field distribution of the motor should be equal to or slightly larger than 2/3 of the flat top wave to provide the largest possible magnetic flux, so that the brushless motor has a large electromagnetic torque.

2. For DC brushless motors with low vibration, low noise, low spark, low output power and efficiency requirements, the internal gap magnetic field distribution should be flat-top or sine wave with distance less than 1/3 to ensure the applicability of such motors. Obtaining gap magnetic field waves with different distribution shapes is not only related to the reasonable design of the magnet structure shape and the magnetic orientation chosen by the magnet, but also related to the magnetization method of the magnet, i.e. design of the magnetizing technique.
