Product Selection | Model Naming Rules
1. Product Selection Table
This selection table is intended to provide users with detailed product selection references. Please note the following points when using it:
- Protocol Compatibility: The communication protocols of the entire product series are consistent, and different models can be used in combination.
-
Structural Compatibility: Products in the 25-50kg series have uniform appearance dimensions and mounting holes, enabling seamless replacement and upgrade.
-
Torque Description: The marked torque parameter refers to the static torque, i.e., the maximum force the product can bear in a static state. During dynamic motion, the actual bearing torque is usually 30%-40% of the static torque. In design and application, please select products reasonably according to this ratio to ensure that they can work safely and stably under dynamic conditions.
-
Power Supply Selection: Please configure a power supply with sufficient power according to the voltage and locked-rotor current of the selected product to avoid the product entering protection due to insufficient power.
-
Special Requirements: If users have special functional requirements, please contact technical support for further consultation and customized services.
