Fatek Servo types: Precise motion control solution

Servo motors are important actuators in the automation industry, used for precise and flexible motion control for many different applications. Fatek is one of the leading reputable servo motor manufacturers in the market, providing a variety of servo types with many outstanding features and advantages. This article will introduce details about Fatek Servo types, helping you choose the product that suits your needs.

• Small Servos: These are compact servo motors suitable for applications where space is limited or where smaller loads need to be controlled with precision.
• Medium Servos: These servos are larger and more powerful, capable of handling moderate to heavy loads while still maintaining accuracy and responsiveness.
• Large Servos: These are heavy-duty servo motors designed for industrial applications requiring high torque and precision control, such as robotic arms or CNC machinery.
• Extra-Large Servos: In some cases, particularly in heavy industrial settings or specialized applications, there might be a need for extra-large servo motors capable of handling extremely heavy loads.

Fatek servos can be classified according to two main motor types: brushless DC motors and permanent magnet AC synchronous motors [source].

Brushless DC (BLDC) Motors

These are the most common type of servo motor used in industrial automation. They use a DC power source but have their brushes replaced with electronically controlled switches. This design offers several advantages over brushed DC motors, including:

• Higher efficiency and longer lifespan due to reduced friction
• Lower maintenance requirements since there are no brushes to wear out
• Improved speed control due to precise electronic commutation

BLDC motors are generally smaller and lighter than AC synchronous motors, making them well-suited for applications requiring high speed and precision control.

Permanent Magnet AC Synchronous Motors

These motors use a permanent magnet rotor and a stator with windings that are energized by an AC current. The interaction between the magnetic fields creates torque that rotates the motor shaft. AC synchronous motors offer several advantages over BLDC motors, including:

• Higher torque output, making them suitable for demanding applications
• Simpler motor construction, potentially leading to lower cost
• Higher operating speeds

Classify Fatek Servos according to controller type

Fatek servos can be classified according to two main controller types: analog controllers and intelligent controllers [source].

Analog Controllers

Analog controllers are the simpler type of servo controller. They receive an analog voltage signal as input, which corresponds to the desired position, speed, or torque of the servo motor. The controller then amplifies this signal to drive the servo motor.

Analog controllers are typically less expensive and easier to set up than intelligent controllers. However, they offer less flexibility and control over the servo motor. For instance, they cannot perform complex motion profiles or compensate for errors.

• Implementing complex motion profiles
• Compensating for errors
• Communicating with other devices on a network

Intelligent Controllers

Intelligent controllers are more sophisticated than analog controllers. They use a microprocessor to control the servo motor and can receive digital signals as input. This allows for more precise control of the servo motor’s position, speed, and torque.

Intelligent controllers can also perform a wider range of functions, such as:

• Implementing complex motion profiles
• Compensating for errors
• Communicating with other devices on a network

Here are some typical Fatek Servo types classified according to their motor type:

  • Cons: More expensive and complex to set up

Servo Fatek is widely used in many different industries, including:

• Feedback System: Decide on the type of feedback system needed for precise position control. Options may include incremental encoders, absolute encoders, or resolver feedback. Select a servo with a feedback system that meets your accuracy and resolution requirements.
• Size and Mounting: Ensure that the physical dimensions and mounting configuration of the servo motor are compatible with your application’s space constraints and mounting requirements.
• Environmental Conditions: Consider the environmental factors such as temperature, humidity, vibration, and dust exposure in your application environment. Choose a servo motor with appropriate protection ratings (e.g., IP65) to ensure reliable operation under these conditions.
• Communication and Control Interface: Check compatibility with your control system and communication protocols (e.g., EtherCAT, Modbus, CANopen). Ensure that the servo motor can be seamlessly integrated into your existing automation setup
