servo motorIt is mainly divided into two categories: DC servo motors and AC servo motors. Among them, AC servo motors can be further divided into synchronous and asynchronous motors (commonly used synchronous motors in motion control), and brushless DC servo motors can also be regarded as a special form of AC servo. In addition, according to their functions and application scenarios, they can be further subdivided into position rotation servo motors, continuous rotation servo motors, and linear servo motors.
servo motorSelection suggestion:
Clear application requirements:
Load requirements: Determine the type of load, weight, and torque requirements to be driven, and select the appropriate motor type and specifications.
Motion control accuracy: Select control accuracy according to actual needs, and for high-precision applications, choose servo motors with low error and high resolution.
Power requirement: Determine the required power range based on actual application, and high-power motors are suitable for high-speed and high load scenarios.
Consider environmental factors:
Work environment: Choose motors with good environmental adaptability, such as protection level, high temperature resistance, etc.
Temperature and humidity: In high temperature or high humidity environments, choose servo motors that can adapt to these conditions.
Understand the requirements of the control system:
Control system type: Select the corresponding servo motor type based on the type of control system (such as closed-loop control, open-loop control).
Interface type: Consider the interface type of the control system (such as analog interface or digital interface), and choose a motor compatible with the system.
Considering long-term reliability and maintenance costs:
Brand and reputation: Choose manufacturers with good brand reputation and after-sales service to reduce equipment failures and maintenance frequency.
Maintenance cost: Considering the maintenance cost of the motor, such as the cost of replacing parts and the repair cycle, choose a servo motor with relatively low maintenance cost and easy maintenance.
Technical details and parameter selection:
Encoder type: Choose the appropriate encoder type according to application requirements. For situations where long-term operation and frequent power outages are required, a battery type absolute encoder can be selected.
Inertia size: Choose the appropriate inertia type (large, medium, small inertia) according to the application scenario. Large inertia motors are suitable for high-speed operation and high load conditions, while small inertia motors are suitable for fast response and precise control.
Type of shaft: Choose the appropriate shaft type according to the actual application scenario. If long-term stable operation is required and the working environment is harsh, shafts with oil seals can be selected.
