Brushed motor
A brushed motor is a rotary electric machine that incorporates carbon brushes to convert electrical energy into mechanical energy (as a motor) or to convert mechanical energy into electrical energy (as a generator).
Brushed motors are the foundation of all electric motors, characterized by rapid start-up, prompt braking, smooth speed regulation over a wide range, and relatively simple control circuitry.

Brushless motor
A brushless DC motor consists of the motor itself and a driver, making it a typical mechatronic product. Because the brushless DC motor operates in a self-controlled manner,
Therefore, unlike synchronous motors with variable-frequency drives that require additional starting windings on the rotor for heavy-load starts, it does not experience oscillations or loss of synchronism during sudden load changes. Medium
High-energy-density rare-earth neodymium-iron-boron (Nd-Fe-B) materials are now commonly used for the permanent magnets in small-capacity brushless DC motors. Consequently, rare-earth permanent-magnet brushless ele
The volume of the motor is one frame size smaller than that of a three-phase induction motor with the same rating.

Servo motor
A servo motor is an electric motor used in servo systems to control the motion of mechanical components; it is an auxiliary motor that provides indirect speed variation.
Servo motors enable highly precise control of speed and position accuracy, converting voltage signals into torque and rotational speed to drive the controlled object. The rotor speed of a servo motor
It is controlled by the input signal and responds rapidly; in automatic control systems, it serves as an actuating element and features a small electromechanical time constant, high linearity, and a low starting voltage.
These characteristics enable the received electrical signal to be converted into angular displacement or angular velocity output at the motor shaft. They are broadly classified into two main types: DC servo motors and AC servo motors, with their primary
Its characteristic is that there is no self-rotation when the signal voltage is zero, and the rotational speed decreases uniformly as the torque increases.

Gear motor
A geared motor refers to an integrated assembly of a gearbox and an electric motor. Such an assembly is also commonly called a gear motor or geared motor. Typically, it is manufactured by specialized gearbox manufacturers, who integrate the gearbox with the motor and supply the complete unit as a packaged system.
