Is a permanent magnet motor an AC motor or a DC motor?
A permanent magnet motor is a type of motor that can operate as either an AC motor or a DC motor.
When acting as an AC motor:
When a permanent magnet motor is powered by alternating current (sine wave or square wave), it acts as an AC motor. At this time, the current in the armature winding is driven by the alternating current to generate a rotating magnetic field. This magnetic field interacts with the magnetic field of the permanent magnet on the rotor to generate torque and drive the motor to rotate.
When acting as a DC motor:
When a permanent magnet motor is powered by DC, it acts as a DC motor. At this time, the current in the armature winding generates a constant magnetic field, which interacts with the magnetic field of the permanent magnets on the rotor to generate torque and drive the motor to rotate.
Therefore, the permanent magnet motor has the characteristics of both AC motor and DC motor, and can achieve two different working modes by changing the power supply method.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
