Brushless motors rely on precise magnetic field control. Bonded NdFeB magnets, as the core components of motors, can provide stable and strong magnetic force. The following is a detailed introduction to bonded NdFeB ring magnets for gimbal brushless motors.
Bonded NdFeB ring magnets are usually used in the rotor part of gimbal brushless motors. Common specifications and sizes can be customized according to motor requirements. The following are common parameters:
Inner diameter: It can be designed according to the size of the motor shaft, usually ranging from a few millimeters to tens of millimeters. Outer diameter: Determines the overall magnetic field strength of the motor and is usually designed according to the power requirements of the motor. Thickness: Bonded NdFeB magnets can be designed to be very thin, usually ranging from 0.5mm to several millimeters. The smaller the thickness, the more it helps to achieve a more compact motor design.
Magnetic field characteristics of bonded NdFeB ring magnets:
Multi-pole magnetization: Gimbal brushless motors usually require multi-pole magnetized magnets to achieve more precise magnetic field switching. Bonded NdFeB ring magnets can be designed with multi-pole magnetization through the magnetization process, which is suitable for high-resolution positioning and speed control.
Temperature resistance: The Curie temperature of bonded NdFeB magnets is usually low, but by selecting the right adhesive and optimizing the process, its operating temperature can be effectively increased to meet the temperature requirements of the gimbal brushless motor.
Application advantages:
High-precision control: Bonded NdFeB magnets are suitable for precise position control due to their stable magnetic properties and can be formed into uniform rings, which is crucial for gimbal equipment
Low weight: The bonding process makes its magnet density lower, which can reduce the overall weight of the motor and improve the response speed and efficiency of the equipment.
Low noise and high efficiency: Compared with traditional brushed motors, brushless motors equipped with bonded NdFeB magnets have lower noise and higher efficiency during operation.
