Summary

The material, remanence density, coercivity, and other performance parameters of permanent magnets are crucial to motor performance. For example, high-performance neodymium iron boron permanent magnets have high remanence and coercivity, which can generate a stronger magnetic field, improving the motor's torque and power density.

Permanent Magnet Performance The material, remanence, coercivity, and other performance parameters of permanent magnets are crucial to motor performance. For example, high-performance neodymium iron boron permanent magnets have high remanence and coercivity, which can generate stronger magnetic fields, improving the motor's torque and power density.

Winding Parameters The number of turns, wire diameter, and winding configuration affect the motor's inductance, resistance, and magnetomotive force distribution. Rational design of winding parameters can optimize the motor's electromagnetic performance, reduce copper losses, and improve efficiency.

Air Gap Size The air gap is the gap between the stator and rotor in the motor. The air gap size affects the motor's magnetic field distribution and magnetic resistance. Too large an air gap increases magnetic resistance, increases excitation current, and reduces the power factor; too small an air gap can easily cause friction between the stator and rotor, and increase assembly difficulty.

Printing industry case studies

The core demands of the printing and packaging industry for special motors are high precision, high response, and high reliability. Future development will focus on precise control, green energy saving, and intelligent operation and maintenance. When selecting motors, it is necessary to combine printing processes (such as offset printing and flexographic printing), material characteristics (such as film and cardboard), and production capacity targets. Priority should be given to the synchronous performance of the servo system, the motor protection level, and the energy efficiency level to meet the dual requirements of quality and efficiency in the high-end packaging market.
