100W 24V DC Servo Motor

DC servo motor refers specifically to DC brushed servo motor - the motor has low cost, simple structure, large starting torque, wide speed range, easy control, requires maintenance, but is easy to maintain (replace carbon brushes). DC servo motors have good starting, braking and speed regulation characteristics, and can easily achieve smooth speed regulation in a wide range. Therefore, they are often used in production equipment that requires high speed regulation performance of servo motors.

The following describes the features of the product. The 100W DC servo motor boasts an IP55 protection grade and an F class insulation structure. Its optimized winding end structure contributes to minimized copper and iron loss, resulting in a compact design that is lightweight, exhibits low temperature rise, and attains high efficiency at 85%. Utilizing NdFe35 permanent magnet material, the ATO DC brushless servo motors exhibit super coercivity and possess a robust resistance to demagnetization, ensuring stable motor performance. Additionally, these motors offer a combination of low noise, low vibration, and low moment of inertia. With high torque, fast dynamic response, and a wide speed range, they demonstrate a strong overload capacity, capable of handling up to four times the standard load.
There are two main control modes of ATO DC servo motor: One is armature voltage control, which controls the speed and output torque of the motor by controlling the voltage signal applied on both ends of armature winding when the stator magnetic field is unchanged, the other is excitation field control, which changes the intensity of stator magnetic field by changing the magnitude of field current, thereby controlling the speed of the motor and output torque.

When adopting the armature voltage control mode, the armature current can reach the rated value because of the unchanged stator magnetic field, and the corresponding output torque can also reach the rated value, so this mode is also called constant torque speed-regulation mode.

However, When adopting the excitation field control mode, the motor speed can only be changed by reducing the magnetic field, because the magnetic field is nearly saturated under the rated operating conditions. Since the armature current is not allowed to exceed the rated value, the motor speed increases with the decrease of magnetic field, but the output torque decreases and the output power remains unchanged, so this mode is also called constant power speed-regulation mode.
