9. How do you caculate the output rated torque and output rated speed? – Dongming Motor, DC gear motor manufacturing plant, dc planetary gear motor, dc worm gear motor, brushless dc motor, brushless dc gear motor, small dc gear motor, 3v/6v/12v/24v dc gear motor

Gearbox output speed = DC motor speed/gear ratio
Gearbox output torque =DC motor torque*gear ratio*efficiency
