For guidance please look at the gearbox information sheets on pages 13-24. 2 Using the relevant selection chart on these pages, mark the intersection point of the required torque (Nm) and speed (rpm). The required motor output power (W) can be read directly from the graph. Any gearbox above the marked intersection will satisfy the torque requirement. 3 Using the brushed dc motor schedule, select a motor from the relevant power band at maximum efficiency and voltage range. The most important step lies in the accurate definition of the work that you require the motor and gearbox to perform. The selection of a suitable brushed dc motor and gearbox can only be made if the torque and speed can be defined. Of these two parameters, torque is probably the most difficult to identify – please contact us if you need help. These graphs are for continuous running for a life of 2K hours. For operation outside these bands please contact us. DC/Planetary DC/Inline Torque ( Nm) Speed (rpm) Torque (Nm) Speed (rpm)
