Selection and Engineering Support

(1) Selection calculation process

Load analysis: Calculate load inertia, fri

ction torque, and acceleration torque

Inertia matching: The recommended ratio of motor inertia to load inertia is 1:1-1:5

Torque calculation: RMS torque=√ [(acceleration torque ² x acceleration time)+(operating torque ² x operating time)+(deceleration torque ² x deceleration time)]/(total time)

Voltage selection: Match the bus voltage of 160Vdc/320Vdc/640Vdc according to the target speed

(2) Engineering resources

Technical documents: 2D/3D CAD files, wiring diagrams, performance curves

Conversion tool: Inertia/torque/length/power unit conversion table

Compliance certification: CE/UL/cUL/BSC/RoHS/WEEE, SSBSM additionally obtained FDA food contact certification
