400W AC Servo Motor

In the model selection of AC servo motor, the motor power, revolving speed, voltage, driver with reducer or not, with brake or not, installed with encoder and so on must be taken into account. Many users are unfamiliar with these parameter requirements before model selection. As a AC motor supplier, ATO can help users to select the most appropriate servo motor. And we will introduce a high quality and low cost AC servo motor. Powerful 400 watt servo motor at good price, features 1.27 Nm rated torque, 3000 rpm precise speed control. Continuous servo motor is available in a 60mm square flange size, widely used in industrial automation, embroidery machines, printing machinery, CNC machine, wood carving and other fields.
ATO AC servo motors offer a comprehensive range of features that ensure optimal performance in various applications. With a focus on accuracy, these motors employ closed-loop control for position, speed, and torque, effectively addressing the issue of stepper motor out-of-step occurrences. Boasting excellent high-speed capabilities with a rated speed range of 1000-3000 rpm, they exhibit reliable and efficient operation. The adaptability of ATO heavy-duty servo motors is evident in their strong anti-overload capability, allowing them to withstand loads three times the rated torque. This makes them particularly suitable for scenarios involving instant load fluctuations and requiring quick starts. Ensuring stability, the AC brushless servo motors operate smoothly at low speeds, eliminating stepping phenomena commonly associated with stepper motors and proving ideal for applications demanding fast responses. Additionally, these motors demonstrate short dynamic response times for acceleration and deceleration, typically within tens of milliseconds, highlighting their timeliness.


The disparity between brush motors and brushless motors manifests in several key aspects. A brush motor, characterized by its low cost, simple structure, substantial starting torque, and broad speed range, is easily controllable and requires maintenance, involving the periodic replacement of carbon brushes. However, it comes with drawbacks, such as generating electromagnetic interference and having environmental requirements. Consequently, it finds application in general industries and private use where cost sensitivity is paramount. On the other hand, a brushless motor boasts a compact size, light weight, high capacity, rapid response, elevated speed, low inertia, smooth shifting, and stable torque. Despite its complex control system, it facilitates intelligent operation, and its electronic commutation allows for flexible options, including square wave or sine wave commutation. Notably, brushless motors are maintenance-free, ensuring high efficiency, low operating temperatures, minimal electromagnetic radiation, and extended service life. Their versatility makes them suitable for deployment in diverse environments.
